Issues With Getting Started Zephyr Build Steps

[mgeeIOL]

Overview

The three provided samples (mini, demo, supervisor) all fail to either run or build with the steps provided in the README.md. (Specifically the "Quick Zephyr build with our West project" steps)

All attempts were with a b_u585i_iot02a board.

How to Reproduce / Error Messages

Specific issues listed below:

Demo Sample

West build fails, exact command was west build -p always -b b_u585i_iot02a ocre-runtime/src/samples/demo/zephyr

Mini Sample

Successfully builds and flashes, but the container runs out of space on the board and cannot run. See logs:

Attempted to mass erase the board separately before flashing the container but had the same result

Supervisor Sample

Successfully builds, flash fails with the following error:

This looks related to missing a component for the STM32_Programmer_CLI program, this was run on the same system CI was done with ocre legacy so all os / system dependencies from ocre legacy should still be intact.

Expected Behavior / Additional Context

As mentioned above all of these attempts were done on the CI system used with ocre legacy so to my knowledge, despite the widespread changes with the recent refactor, the new build process should still work. as the system requirements should be the same.

For mini and demo, we are missing the board configuration b_u585i_iot02a. These will be added shortly.

For the supervisor sample, the board support is there, and it works for me.

I believe there might be something wrong with your setup as it looks like it is using the system openocd, not the one from Zephyr.

Can you try west -v flash with the supervisor sample and share the full output?

Thank you.

The STM32 Programmer bug is indeed interesting, because the following was working on your machine:
https://github.com/project-ocre/ocre-runtime/pull/109/changes

The CONFIG_STM32_MEMMAP config includes the proper memory map of the external flash for this board, from this cmake:
https://github.com/zephyrproject-rtos/zephyr/blob/main/boards/st/b_u585i_iot02a/board.cmake

While you did this step manually before, somehow through Zephyr it doesn't work anymore right now - maybe due to some installation specifics or path specifics. For example, on my machine STM32 tools are added to my PATH so I can refer to them from whenever. Maybe something like this might be the case, that Zephyr expects this?

After some debugging I was able to get the supervisor sample to work by using overwriting the ExternalLoader path to what we were using previously.
https://github.com/project-ocre/ocre-runtime/pull/109/files

Command used: west flash --extload=/usr/local/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/ExternalLoader/MX25LM51245G_STM32U585I-IOT02A.stldr

After this I was able to get into the runtime fine and use shell commands.

I will wait until the board configurations for the demo and mini samples are implemented before continuing testing.

With added configs, all samples shall build; Known issues for demo sample:
It only runs hello-world and blinky, after it fails because there isn't enough RAM. That will be fixed here: #135
