Question about Zephyr for Jira 3.5.1
Ellen Elferink <E.Elferink@...>
Hello,
We are currently using 2 instances of Jira and Confluence which we are merging into 1 instance.
However, we encounter problems in merging the Zephyr for Jira add-on.
Can you explain to me how to export Zephyr data from one database and
import into another database?
Hope to hearing from you soon.
Met vriendelijke groet / Kind regards,
Ellen Elferink

Re: Bluetooth mesh persistent storage
Hi Johan,
Thanks for the reply. Would it not be simpler to allow access to the
bt_mesh structure by moving the definition from net.h to
include/bluetooth/mesh.h. Would this allow access to all data (keys,
sequence, ...) ? Maybe the data is a bit hidden in the structure.
Regarding the JSON format, I think this is a good idea.
Kind regards,
Jehudi

Another idea (IMO quite nice one) would to be able to use the
Provisioning Database JSON format that should be coming out as a
whitepaper from the SIG. It looks like it's not yet public, so
unfortunately we can't really put any related code upstream for now.
AFAIK Zephyr has a JSON library, so this might not be too much work to
implement.

Does the filesystem work on Qemu_x86?
Hi,
I was wondering if the file system works on the qemu_x86? I tried opening and writing to a file using fs_open and fs_write. However, no file is created.
Any help would be appreciated. Thanks.

Re: Zephyr issue tracking system moved to Github
Hi Anas,
This is not very user friendly atm. For example it is impossible to
find all networking related PR as if I select "area: Networking" I get
only some of the network related PR.
I suggest following change:
* There are too many networking labels, one "area: Networking" is
enough. Now I cannot get a full list of networking PRs because some of
them have more detailed network label applied (and missing the "area:
Networking" label). How are networking related labels tagged, is
zephyrbot automatically setting them? So if I remove (I am not sure if
I can do that) for example label "area: 6LoWPAN", will this start to
work ok or is there some special configuration needed somewhere?
* Other option would always add "area: Networking" label if some other,
more specific, network label is added.
Cheers,
Jukka

Is the http_client sample POST request working correctly?
Hi, I'm testing the POST request on the http_client sample using the board qemu_cortex_m3 on Linux and I was wondering if it is posting correctly? I'm running the http-server.py from net-tools along with everything else that is necessary to get it working (loop-socat.sh and loop-slip-tap.sh).
Everything is successful on both sides, the client successfully posts to the server and server responds with the status OK.
However, I can't seem to get any content from the request on the server side. I can't get the content-length using self.headers in the http-server.py file as it only returns the Host and nothing else.
I'm not sure if I'm getting the content of the POST request correctly from python, or Zephyr's http_client sample POST function isn't working as intended.
Any help would be much appreciated.
Cheers,
Yie

I have another question, if you dont mind.
I have an app that's taking about ~5MB of RAM and ~5.6MB of ROM judging from the 'ram_report' and 'rom_report'. Is there a way to reduce the size of those? It is much bigger because I've included other functionalities such as multi-threading and networking.
Do I remove functionalities I don't need using 'make menuconfig'?

qemu-system-arm is just a VM that can emulate, among others, Cortex-M
MCUs. `qemu_cortext_m3` board is in fact emulated by qemu. Memory
usage of a running Qemu process does not directly (or otherwise
easily) translate to the memory usage in the target system.
Haven't looked at the reports for some time, but `ram_report` is
likely a listing statically allocated data that would normally be
copied into RAM during system initialization. `rom_report` likely
lists the size of each symbol (i.e. non-inlined function in the code).
So, you're more realistically looking at ~4kB of RAM and ~7kB of
flash.

Hi Savinay,
Thanks for your help. Are you using minicom? My samples such as beacon and hello_world compiles and it is successful but I can't see any output on minicom. I did this before with the arduino_101 and minicom and I would see the "beacon demo starting" come up on minicom and such. Do you know what could be going on? I've also tried picocom, cutecom, and gtkterm, but those didn't work as well. Thank you,
Hi Tamra,
Flash sample/synchronization/ application you will be able to see the prints. Flashing via dfu-util for tinytile works fine. After flashing "hello world" sample application ,a reset is required which is disconnecting /dev/ttyACM0 not sure
Why it is happening.
Regards
savinay

Hi,
Is there an inter-process communication functionality on Zephyr running on Linux for Qemu?
I have an application on Zephyr that gets data from an external source.
However, since I do not have the actual device, I will be emulating this on Qemu. So I will have 2 applications, one solely for generating the output.
However, how can these two applications communicate? I know this can be done in C using named pipes. Is it possible to do that with Zephyr as well?
Any help would be much appreciated. Thanks.
Cheers,
Yie

We use QEMU_EXTRA_FLAGS for providing this parameter for QEMU, for example in bluetooth we may run btproxy on Linux host and QEMU_EXTRA_FLAGS like following:
QEMU_EXTRA_FLAGS = -serial unix:/tmp/bt-server-bredr

Hello all,
I am trying to flash my tinytile. When I use the commands make BOARD=tinytile flash or make flash or the dfu-util command, I get the errors below. Tinytile does not have a jtag connection and it seems like it's looking for a jtag connection. I want to flash using the dfu-util command. I was able to do this with my arduino_101. I am trying to use the same command, dfu-util -a x86_app -D outdir/tinytile/zephyr.bin. This part is successful. However, when I open minicom, minicom freezes and it appears the code is not being executed. Since I can't see anything in minicom, I am not sure how to debug this issue or what's really going on. Any ideas? It would be super great if someone could point us in the right direction. Thank you for your time!

qemu-system-arm is just a VM that can emulate, among others, Cortex-M
MCUs. `qemu_cortext_m3` board is in fact emulated by qemu. Memory
usage of a running Qemu process does not directly (or otherwise
easily) translate to the memory usage in the target system.
Haven't looked at the reports for some time, but `ram_report` is
likely a listing statically allocated data that would normally be
copied into RAM during system initialization. `rom_report` likely
lists the size of each symbol (i.e. non-inlined function in the code).
So, you're more realistically looking at ~4kB of RAM and ~7kB of
flash.

Re: Zephyr File System Not Working
Thank you so much! I tried building it on qemu_x86 and it works fine. However, if you don't mind, I have another question regarding the file system. This is my code:
I'm currently trying to open the file to write to it. It seems to be opening fine, but I cannot call the fs_write/fs_seek don't seem to be working for me.. The only output I am getting is "Done opening file".
Can I get any help on this? Thanks once again.
Cheers.

If you are looking at emulation, you probably should try qemu_x86 which has more storage configured, this will build just fine.

Do you require the attachments of my app or the hello_world sample?
Here's the pastebin of the reports and config file for my app:

Re: Is it possible to have two processes communicate in ARM Qemu?

Thanks for your reply. Are there any other QEMU_EXTRA_FLAGS that allows

We use QEMU_EXTRA_FLAGS for providing this parameter for QEMU, for
example in bluetooth we may run btproxy on Linux host and
QEMU_EXTRA_FLAGS like following:
QEMU_EXTRA_FLAGS = -serial unix:/tmp/bt-server-bredr

Re: How to reduce footprint and size of applications in Zephyr
Hi Yie, That seems really weird. Could you attach the output of ram_report and rom_report in a pastebin/gist/attachment? And if that's not a problem, please provide your .config file. You can find it inside your build's output folder.
Best regards,
Thiago
I see. That makes a lot of sense. Thank you Maciek!
I have another question, if you dont mind.
I have an app that's taking about ~5MB of RAM and ~5.6MB of ROM judging from the 'ram_report' and 'rom_report'. Is there a way to reduce the size of those? It is much bigger because I've included other functionalities such as multi-threading and networking. Do I remove functionalities I don't need using 'make menuconfig'?
Cheers,
Yie

Re: How to include C library that is not in Zephyr
Hi Hui,
Newlib is included in zephyr. To enable newlib, just add CONFIG_NEWLI_LIBC=y to prj.conf file. The conf file can be found in the same directory that your makefile is. Then your zephyr environment should simply switch from miminal to newlib. Best, Jie
