Hi all,

This week we will look at GPIO:

- GPIO: Update on progress
- Look at the PRs with driver conversion (https://github.com/zephyrproject-rtos/zephyr/issues/18530)
- Check users of GPIO APIs: https://github.com/zephyrproject-rtos/zephyr/issues/20017
- Tips for converting users can be found here: https://github.com/zephyrproject-rtos/zephyr/issues/20017#issuecomment-549315497 (thanks Peter!)
- Any additional outstanding PRs to topic-gpio

Additional items in the "Triage" column in the GitHub project may be discussed if time permits.
If you want an item included in the meeting, please add it to the GitHub project.

Hi,
I have nrf52840 on my custom board (Based on IMX6, Running Yocto linux) which is connected over UART.
I want to do an OTA of zephyr OS on that chip over serial/ble and for that i had already tried following things.
1) I have build smp_svr and flashed it to nrf52840 so that i can use 'mcumgr' command line tool for the flashing.
Referred https://docs.zephyrproject.org/1.14.0/samples/subsys/mgmt/mcumgr/smp_svr/README.html?highlight=build%20smp_svr to know how to use 'mcumgr'.

Now, when i use mcumgr to communicate 'hello' message over serial/UART, It shows error of connection timed out. (Also tried with -t switch, but no luck).
Command used are :
sudo mcumgr --conntype serial --connstring='dev=/dev/ttymxc0,baud=115200' echo hello
--> So it's not able to open the connection using mcumgr and not getting any reply (Getting timeout).

Hi,

I think the https://github.com/BobBuildTool/bob-example-embedded
example is the most interesting one to the Zephyr community (even
though it's using FreeRTOS+Linux at the moment).

If you guys have a particular example that already builds multiple
dependent Zephyr images then we can try to setup some Bob recipes
that builds the same thing...

/Jan

You can take a look at the open-amp sample, it creates 2 zephyr images:

https://github.com/zephyrproject-rtos/zephyr/tree/master/samples/subsys/ipc/openamp

I'm currently preparing some recipes. It will post them with some
instructions how to build in the next days once I got it working...

Ok, here it is: https://github.com/jkloetzke/zephyr-example-recipes

There is a README.md with a short overview. Basically you just have to
clone the recipes and build it:

$ git clone https://github.com/jkloetzke/zephyr-example-recipes.git \
--recurse-submodules
$ cd zephyr-example-recipes
$ bob dev demo::zephyr -j

Make sure that you have the latest version of Bob. The demo recipes use
the "layers" feature that has not been released yet. It's best to
install Bob via:

$ pip3 install [--user] git+https://github.com/BobBuildTool/bob

Otherwise have a look at

https://bob-build-tool.readthedocs.io/en/latest/installation.html

for further options.

Note that the recipes do not use west but clone the involved
repositories directly and calls cmake itself. This has the advantage
that there is only one tool that fetches/updates sources.

Seems like zephyr.yaml is the file controlling this in a map called
checkoutSCM. (I haven't read the bob docs, but I'm sure that's covered
there.)

I made a quick hack west extension to convert the upstream zephyr
manifest into the format used there, in case it's useful:

https://github.com/mbolivar/tree/bob-the-builder

Example:

$ west gen-bob-checkout
checkoutSCM:
- commit: 07380358424edecdefeb28ed7cb43e27b530014d
dir: zephyr
scm: git
url: https://github.com/zephyrproject-rtos/zephyr

dir: modules/lib/civetweb
scm: git
url: https://github.com/zephyrproject-rtos/civetweb
[...]

Just in case it's useful to anyone who wants all the projects but
doesn't want to do the paperwork themselves.

Additionally
the OpenAMP sample was put into a dedicated repository because some
refactoring was needed, namely removing the "ExternalProject" link
between the images.

The recipes also show how a toolchain is defined in the recipes. There
is no need for the user to install a toolchain but the right one is
brought in by the recipes automatically. Usually this is done with all
involved tools to maximize reproducibility but this would have just made
the example more complicated.

Sounds great!

Please be aware of this in that case:

https://github.com/zephyrproject-rtos/zephyr/issues/19918

It would be good to see a solution that doesn't have this issue.

This is handled well by Bob. The explicit goal of Bob is to feel like
"make" even though Bob controls the build of whole packages.

Have fun.

Hi Kees and Jan,

Zephyr links the code for a code partition specified in the dts as shown above by Jan by specifying in the proj.conf file:

Hi,

I want to add support for my Sodaq boards. These are SAMD21, Arduino Zero compatible boards with the Arduino bootloaders on them. So, I want the code (flash) to be located at an offset of 0x2000. How do I specify this offset?

Hi all,
I would like to add support for NXP frdm_kl46z evaluation board, starting from what already done for frdm_kl25z.

If useful I will move forward.

Hi Giri,
currently we have multicast group support only implemented for IPv6.
It would not be a big task to implement mcast listener support for
IPv4 if you want to do that. As always, patches are welcome.

For reference, there already exists a ticket for this feature:
https://github.com/zephyrproject-rtos/zephyr/issues/2336 , so
interested parties are welcome to "watch" it to stay in loop on updates
and/or coordinate work.

Cheers,Jukka

Hi,

I am trying to implement IPv4 based multicast listener application.
Please let me know, if there are any sample applications in Zephyr
that involve joining to a multicast group and listening on a port.

Thanks & Regards,

Hi Sebastian,

On Thu, Oct 31, 2019 at 09:17:01AM +0000, Sebastian Boe wrote:

AFAICT it heavily integrates with bash making it a no-go.

IMHO this depends on what Bob should be used for in the context of
Zephyr. At the BoF session most people agreed that the Multiimage
problem goes beyond Zephyr alone. If Bob (in the current version) is a
viable alternative really depends on the use case.

To what degree does Bob require Linux tools like bash?

At the moment bash is still a hard requirement. There are some other
unix tools required but this is going away in the future.

It is not an option to introduce bash as a dependency for Windows users.

You can use Bob on Windows via MSYS2, though. But I agree that this may
not be an option for everybody at the moment.

Can it be used without bash?

This is in the works. Windows support is definitely on the agenda
because there are a bunch of people that have the same requirement. The
(currently stale) PR

https://github.com/BobBuildTool/bob/pull/258

will be updated in the coming weeks. This requires some amount of
refactoring internally so its taking some time. The idea is to make Bob
independent of the acutally used scripting language. The first step is
to support PowerShell on Windows and then maybe Python for
cross-platform scripts.

Regards,
Jan
