Re: [1.9.0] build broken for windows

Ok. msys2 on Windows 7 Enterprise is BSOD.

So I tried it under citrix and Works but still have the same error:

Re: Problem with echo_server / echo_client samples running in QEMU (No rule to make target 'qemu' ?)

Hi Paul


Thanks for the patch.

I tested again  /samples/net/ieee802154/qemu


Probably the issue comes from qemu <---> qemu set up and this might work on kw41z (as suggested by David).

My kernel version is 4.4.0-96-generic.


For the test with QEMU at least, echo-server / Qemu crashes (Fatal fault in ISR! Spinning...) as soon as echo-client is launched.

Need to check what is wrong at echo-server app end .

Re: IPSP bluetooth sample with QEMU (ping fails)

David Leach
 

Priyanka,

 

I have a branch on my fork that compiles the 802.15.4 echo client/server without any errors. It really is just a couple of project files though so I’m not sure what is happening with your setup. You can check what I did here:

 

https://github.com/dleach02/zephyr/tree/kw41z

 

I’m still playing around with things to get a better understanding of how things are laid out. Anas had suggested that we consider cleaning up the config files in the client/server echo sample … plus I’m not so convinced things are working that well.

Subject: Re: [Zephyr-users] IPSP bluetooth sample with QEMU (ping fails)

 

Hi Paul

 

Thank you for the details and suggestions. 

Sure, I am going to add "+1" to the PR :-)

 

In fact, what we are interested in is not really BLE, but having IPv6 over KW41Z communicating with a peer board.

So we had been exploring and testing different connectivity options.

 

1) I tested IPv6 over BLE (IPSP sample) with QEMU and it works finally :-). However, Maureen informed us about some legal issues related to enabling BLE on KW41Z. So I understand we won't be able to use the BLE connectivity option on real hardware.

 

2) Now as a possible alternative option, I started with testing "IPv6 over IEEE802.15.4" with QEMU first and then we will test with kw41z.

 

However,  with the most recent zephyr master branch (after I did "git pull" today), echo_server / echo_client failed for target QEMU. 

Nashif, Anas  has just provided a fix for this, I will test again with the fix. Thanks.

 

The fix might resolve "target 'qemu'" issue, however, another issue is that echo_client fails to compile with errors like 

(undefined reference to `net_app_send_pkt'....)

 

Thanks

Priyanka

Hello Priyanka,

Sorry for the delay with response, I was at Linaro Connect with pretty
packed local program. But we touched some questions you posed
below with Maureen Helm and David Leach of NXP (both are in cc:), so
hopefully I can bring some info.

Another note is that I appreciate that you use Zephyr "user" mailing
list - we have also the "devel" mailing, and some posts there would be
better suited for the user lists. But your posts are actually the
opposite, as they touch Zephyr development matters, so given there're
not many responses, I may suggest to post there too, maybe people
monitor it better.

See also below for more comments.

Not that I know of. And work done by Linaro on KW41Z/KW40Z revolves
around 802.15.4 instead. For example, there's a Zephyr driver
already in the tree, and 15.4-over-FSCI driver in the review:
https://github.com/zephyrproject-rtos/zephyr/pull/868 . I found a bit
strange there was no talk about BLE support, as "native" Hexiwear
support is all about BLE (and communication with smartphones), and
vice-versa, there's no sign of 15.4 support.

At the Connect, David mentioned that BLE controller/stack might have
been licensed from 3rd party vendor, and that poses additional
organizational complications to its support in Zephyr.

However, if you have a two-core system, like Hexiwear, where KW40Z is
used completely as a block box BLE controller, you might be able to run
it, if it uses the standard HCI protocol. At least we have couple of
boards in Zephyr which use a similar arrangement.

Same here at Linaro, except we want to do it over 15.4 ;-).

David (re)tested 6lowpan over 15.4 with KW41Z, it mostly works.
Reproducing that is my immediate TODO once I finish with post-travel
backlog.

Well, it works (as an "experimental technology" would, with various
requirements and caveats).

I mention previously
https://github.com/zephyrproject-rtos/zephyr/pull/1185 , which
documents steps I went thru to get IPv6 over BLE running. I'd like to
extend an invitation to add a "+1" style comment to it if you find it
useful and would like to see it in the official documentation
(otherwise, the reviewers of that patch are people who also maintain
Linux kernel side of BLE and Bluez, and they assume that everyone runs
the latest kernel and Bluez, which is of course not true ;-) ).

Reported by James Prestwood: Running using Zephyr's IPv6 over BLE seems to have been broken recently. I have tested with iotivity-constrained and do see some data but things are not working correct...

Well, great news! What kernel version do you use? The latest news is
that kernel 4.12 finally should fix all the issues (known issues) with
6lowpan/ble support:
https://github.com/zephyrproject-rtos/zephyr/commit/a4e176b6a33ebbb0732e4a1d8cb174bb57a6f510

github.com

Since 4.12 Linux kernel has fixes required to comply to RFC 7668. Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@...>



If you have below that, might as well be not too surprised with errors,
etc. ;-). I myself running 4.10, waiting while my OS vendor will issue
an (still experimental) 4.12 upgrade.

Thanks for the report. In future cases, feel free to open a bug at
https://github.com/zephyrproject-rtos/zephyr/issues .

I posted a patch to solve this issue:
https://github.com/zephyrproject-rtos/zephyr/pull/4166


This is why I had today switched to the most recent version of zephyr.

Any idea, what am I missing here? Thanks.

Re: Projects in Zephyr v1.9.0 always rebuild even no changes in source code. How to fix this?

Carles Cufi
 

Hi Alan,

 

Unfortunately I don´t think there is a fix as of yet. The transition to CMake will of course resolve this issue but in the meantime no one has seriously looked into this since it seems like most of our current users develop on Linux. I do build on Windows regularly but have not looked into this yet. If I do I will update the GitHub issue.

Carles

Hi Carles,

Yes i am working on the MSYS2 environment. I will try the fix mentioned in issue 3682.

Thanks for your help!

Hi,

 

I realized that the projects on Zephyr v1.9.0 release will always re-build when you type "make" even there is no changes in the source code. This does not happens on v1.8.0 release. 

 

It would be quite annoying during source code development and will waste a lot of time waiting. Is there a way to fix this?

Hello

 

While testing with recent zephyr (master branch),

echo_server and echo_client samples running in QEMU fail.

 

Both "make server" and "make client" fail for QEMU with error

No rule to make target 'qemu'.  

 

I did "git pull" today, after that I get the error "No rule to make target 'qemu'.

Whereas with 3 weeks older master branch, this error was not there, but even earlier the sample "echo-client" failed to compile with errors such as "undefined reference to net_app_send_pkt" as shown below.

 

I want to test IPv6 over 802.15.4 so I test the sample application

zephyr/samples/net/ieee802154/qemu

 

Here are the steps to show my test set up:

 

Terminal 1  echo_server

I modified makefile to  do "make server" else I also tried "make BOARD=qemu_x86 CONF_FILE=prj_qemu_802154.conf server"

or

Re: IPSP bluetooth sample with QEMU (ping fails)

Priyanka
 

Hi Paul

Thank you for the details and suggestions. 
Sure, I am going to add "+1" to the PR :-)

In fact, what we are interested in is not really BLE, but having IPv6 over KW41Z communicating with a peer board.
So we had been exploring and testing different connectivity options.

1) I tested IPv6 over BLE (IPSP sample) with QEMU and it works finally :-). However, Maureen informed us about some legal issues related to enabling BLE on KW41Z. So I understand we won't be able to use the BLE connectivity option on real hardware.

2) Now as a possible alternative option, I started with testing "IPv6 over IEEE802.15.4" with QEMU first and then we will test with kw41z.

However,  with the most recent zephyr master branch (after I did "git pull" today), echo_server / echo_client failed for target QEMU. 
Nashif, Anas  has just provided a fix for this, I will test again with the fix. Thanks.

The fix might resolve "target 'qemu'" issue, however, another issue is that echo_client fails to compile with errors like 
(undefined reference to `net_app_send_pkt'....)

Thanks
Priyanka

Hello Priyanka,

Sorry for the delay with response, I was at Linaro Connect with pretty
packed local program. But we touched some questions you posed
below with Maureen Helm and David Leach of NXP (both are in cc:), so
hopefully I can bring some info.

Another note is that I appreciate that you use Zephyr "user" mailing
list - we have also the "devel" mailing, and some posts there would be
better suited for the user lists. But your posts are actually the
opposite, as they touch Zephyr development matters, so given there're
not many responses, I may suggest to post there too, maybe people
monitor it better.

See also below for more comments.

Not that I know of. And work done by Linaro on KW41Z/KW40Z revolves
around 802.15.4 instead. For example, there's a Zephyr driver
already in the tree, and 15.4-over-FSCI driver in the review:
https://github.com/zephyrproject-rtos/zephyr/pull/868 . I found a bit
strange there was no talk about BLE support, as "native" Hexiwear
support is all about BLE (and communication with smartphones), and
vice-versa, there's no sign of 15.4 support.

At the Connect, David mentioned that BLE controller/stack might have
been licensed from 3rd party vendor, and that poses additional
organizational complications to its support in Zephyr.

However, if you have a two-core system, like Hexiwear, where KW40Z is
used completely as a block box BLE controller, you might be able to run
it, if it uses the standard HCI protocol. At least we have couple of
boards in Zephyr which use a similar arrangement.

Same here at Linaro, except we want to do it over 15.4 ;-).

David (re)tested 6lowpan over 15.4 with KW41Z, it mostly works.
Reproducing that is my immediate TODO once I finish with post-travel
backlog.

Well, it works (as an "experimental technology" would, with various
requirements and caveats).

I mention previously
https://github.com/zephyrproject-rtos/zephyr/pull/1185 , which
documents steps I went thru to get IPv6 over BLE running. I'd like to
extend an invitation to add a "+1" style comment to it if you find it
useful and would like to see it in the official documentation
(otherwise, the reviewers of that patch are people who also maintain
Linux kernel side of BLE and Bluez, and they assume that everyone runs
the latest kernel and Bluez, which is of course not true ;-) ).

Reported by James Prestwood: Running using Zephyr's IPv6 over BLE seems to have been broken recently. I have tested with iotivity-constrained and do see some data but things are not working correct...

Well, great news! What kernel version do you use? The latest news is
that kernel 4.12 finally should fix all the issues (known issues) with
6lowpan/ble support:
https://github.com/zephyrproject-rtos/zephyr/commit/a4e176b6a33ebbb0732e4a1d8cb174bb57a6f510
github.com
Since 4.12 Linux kernel has fixes required to comply to RFC 7668. Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@...>


If you have below that, might as well be not too surprised with errors,
etc. ;-). I myself running 4.10, waiting while my OS vendor will issue
an (still experimental) 4.12 upgrade.

Re: Problem with echo_server / echo_client samples running in QEMU (No rule to make target 'qemu' ?)

Nashif, Anas
 

Try this fix:

 

https://github.com/zephyrproject-rtos/zephyr/pull/4158

 

From: zephyr-users-bounces@... [mailto:zephyr-users-bounces@...] On Behalf Of Priyanka Rawat
Sent: Tuesday, October 3, 2017 9:03 AM
To: zephyr-users@...
Subject: [Zephyr-users] Problem with echo_server / echo_client samples running in QEMU (No rule to make target 'qemu' ?)

 

Hello

 

While testing with recent zephyr (master branch),

echo_server and echo_client samples running in QEMU fail.

 

Both "make server" and "make client" fail for QEMU with error

No rule to make target 'qemu'.  

 

I did "git pull" today, after that I get the error "No rule to make target 'qemu'.

Whereas with 3 weeks older master branch, this error was not there, but even earlier the sample "echo-client" failed to compile with errors such as "undefined reference to net_app_send_pkt" as shown below.

 

I want to test IPv6 over 802.15.4 so I test the sample application

zephyr/samples/net/ieee802154/qemu

 

Here are the steps to show my test set up:

 

Terminal 1  echo_server

-----------------------------------

I modified makefile to  do "make server" else I also tried "make BOARD=qemu_x86 CONF_FILE=prj_qemu_802154.conf server"

 

zephyr/samples/net/echo_server$ make server

or

zephyr/samples/net/echo_server$ make CONF_FILE=prj_qemu_802154.conf server

Hi,

 

I realized that the projects on Zephyr v1.9.0 release will always re-build when you type "make" even there is no changes in the source code. This does not happens on v1.8.0 release. 

 

It would be quite annoying during source code development and will waste a lot of time waiting. Is there a way to fix this?

I can't reproduce this. So, feel free to provide additional
information, steps to reproduce, etc. Actually, if you would have that
information and "always rebuilds" matter is confirmed, feel free to
open a bug with that info directly:

Re: IPSP bluetooth sample with QEMU (ping fails)

Paul Sokolovsky
 

Hello Priyanka,

Sorry for the delay with response, I was at Linaro Connect with pretty
packed local program. But we touched some questions you posed
below with Maureen Helm and David Leach of NXP (both are in cc:), so
hopefully I can bring some info.

Another note is that I appreciate that you use Zephyr "user" mailing
list - we have also the "devel" mailing, and some posts there would be
better suited for the user lists. But your posts are actually the
opposite, as they touch Zephyr development matters, so given there're
not many responses, I may suggest to post there too, maybe people
monitor it better.

See also below for more comments.

Hi

Thank you Paul for the suggestions.
We are waiting for the real hardware (KW41Z board), meanwhile I
should test IPSP with QEMU.

Unfortunately, I do not have a 96b_carbon board. Does anyone know if
IPv6 over BLE, IPSP work on FRDM boards?
Not that I know of. And work done by Linaro on KW41Z/KW40Z revolves
around 802.15.4 instead. For example, there's a Zephyr driver
already in the tree, and 15.4-over-FSCI driver in the review:
https://github.com/zephyrproject-rtos/zephyr/pull/868 . I found a bit
strange there was no talk about BLE support, as "native" Hexiwear
support is all about BLE (and communication with smartphones), and
vice-versa, there's no sign of 15.4 support.

At the Connect, David mentioned that BLE controller/stack might have
been licensed from 3rd party vendor, and that poses additional
organizational complications to its support in Zephyr.

However, if you have a two-core system, like Hexiwear, where KW40Z is
used completely as a block box BLE controller, you might be able to run
it, if it uses the standard HCI protocol. At least we have couple of
boards in Zephyr which use a similar arrangement.

Eventually, we would like to test the following scenario;
KW41Z running Zephyr + 6loble (IPv6 over BLE) with a x86 Linux +
KW41Z-FRDM / USB.
Same here at Linaro, except we want to do it over 15.4 ;-).

Any idea if IPv6 over BLE / 6lowpan works over KW41Z running Zephyr?
Has anyone tested IPv6 over BLE with Zephyr over KW41Z board?
David (re)tested 6lowpan over 15.4 with KW41Z, it mostly works.
Reproducing that is my immediate TODO once I finish with post-travel
backlog.

What is the current status on IPv6 over BLE?
Well, it works (as an "experimental technology" would, with various
requirements and caveats).


I found some links on IPv6 over BLE, but couldn't figure out much
from them. Is there any other link I should look at?
I mention previously
https://github.com/zephyrproject-rtos/zephyr/pull/1185 , which
documents steps I went thru to get IPv6 over BLE running. I'd like to
extend an invitation to add a "+1" style comment to it if you find it
useful and would like to see it in the official documentation
(otherwise, the reviewers of that patch are people who also maintain
Linux kernel side of BLE and Bluez, and they assume that everyone runs
the latest kernel and Bluez, which is of course not true ;-) ).


https://github.com/zephyrproject-rtos/zephyr/pull/1151
net: l2: bt: Make 6lowpan/BLE be compatible with Linux by default
#1151

https://github.com/zephyrproject-rtos/zephyr/issues/3111
IPv6 over BLE no longer works after commit 2e9fd88 #3111


Update on IPSP sample with QEMU (ping works, but there are errors
like fatal kernel error etc., )
Well, great news! What kernel version do you use? The latest news is
that kernel 4.12 finally should fix all the issues (known issues) with
6lowpan/ble support:
https://github.com/zephyrproject-rtos/zephyr/commit/a4e176b6a33ebbb0732e4a1d8cb174bb57a6f510

If you have below that, might as well be not too surprised with errors,
etc. ;-). I myself running 4.10, waiting while my OS vendor will issue
an (still experimental) 4.12 upgrade.

-----------------------------------------------------------------------------------------------------------------------------------------

I tested IPSP bluetooth sample with QEMU again and ping works now.
Tests with telnet and echo-client work as well.

While testing bluetooth IPSP sample (recent master branch of

I noticed that there are some old issues and bugs reported on the
IPSP sample. However, I couldn't figure out if the bugs/issues
have been resolved already.

What is the current status on the IPSP bluetooth sample? Anyone
tested IPSP sample with Qemu?
I tested it on BOARD=96b_carbon (real hardware) straight before 1.9
release, everything worked well, and I captured docs required to
set it up at
https://github.com/zephyrproject-rtos/zephyr/pull/1185 (if you
would find detailed instructions for setting up IPSP in Zephyr
useful, please add +1 comment to that pull request).

What's your usecase for working with BLE in qemu_x86 in general? I
fully understand and support the idea of being able to run it via
QEMU, so everyone can test it without a real hardware, but based on
your own experience, not everything works smooth there. So, if
you're just interested in BLE and/or IPSP, I'd suggest to try them
on some real board as an alternative to QEMU, that's known to work
pretty well (across few boards).

I myself a novice with BLE support in Zephyr (usually work on other
things), and would be interested to get it work with QEMU too, but
don't know when I'll be able to pay enough attention to it, as I'm
currently working on few other things keeping me pretty busy.


I get the following for the IPSP test:

Problem with echo_server / echo_client samples running in QEMU (No rule to make target 'qemu' ?)

Priyanka
 

Hello


While testing with recent zephyr (master branch),

echo_server and echo_client samples running in QEMU fail.


Both "make server" and "make client" fail for QEMU with error

No rule to make target 'qemu'.  


I did "git pull" today, after that I get the error "No rule to make target 'qemu'.

Whereas with 3 weeks older master branch, this error was not there, but even earlier the sample "echo-client" failed to compile with errors such as "undefined reference to net_app_send_pkt" as shown below.


I want to test IPv6 over 802.15.4 so I test the sample application

zephyr/samples/net/ieee802154/qemu

Here are the steps to show my test set up:


Terminal 1  echo_server

Projects in Zephyr v1.9.0 always rebuild even no changes in source code. How to fix this?

Hi,

I realized that the projects on Zephyr v1.9.0 release will always re-build when you type "make" even there is no changes in the source code. This does not happens on v1.8.0 release. 

It would be quite annoying during source code development and will waste a lot of time waiting. Is there a way to fix this?


Best Regards,

Thread level memory protection is a feature that is currently under development. We are targeting the MMU on x86 and ARM MPUs first. We expect to have this fully working and documented for the LTS release in Q1 2018.

Sorry i'm new.

May I know if is possible to make 2 simple task static task   in the same cpu ,

and this 2 task are protected by MPU of an cortex M4 processor? 

Those 2 task can comunicate only using a queue?

How can do that in zephyr ? is possible or not ? There is an application note?
