Errors building CM0PLUS_DEMO for STM32MP257x-EV1

[HBujanda]

I'm using en.stm32cubemp2-v1-1-0.zip plus patch file en.stm32cubemp2-v1-1-1.zip 

I'm trying to build CM0PLUS_DEMO for STM32MP257x-EV1 for the cortex-M0 core.

I got planty of errors when trying to build it with STM32CubeIDE Version: 1.17.0 Build: 23558_20241125_2245 (UTC):

Failed to generate command line.

reason: Unknown target.

I'm reviewing the 'How to use the Cortex-M0+' document for any advise on how to build the example but it does not give any expecial advise so I assume I have to use CubeIDE:

https://wiki.st.com/stm32mpu/wiki/How_to_use_the_Cortex-M0%2B#Memories_RIF_configuration_example

Other examples for the Cortex-M33 build correctly.

Thanks in advance, Hector.

Hi @HBujanda ,

Just tested and it works fine at my end on Windows. 

Are you on windows or Ubuntu station ? 

Can you share logs and screenshots ?

Hi Olivier,

Which version of en.stm32cubemp2 and CubeIDE are you using?

I'm using windows but a partner is using ubuntu 20.04 and got the same error:

My Windows verison is Windows 10 Enterprise.

As said before, other examples for the CortexM33 build fine.

Hello @HBujanda,

I have reproduce your error on my ubuntu station. 

Could you go into your project's properties then into C/C++ Build --> Settings --> MCU/MPU Settings, and tell us if you can access this menu ?

Just clicking C/C++ Build --> Settings --> MCU/MPU Settings..... produce the same errors screens as when building:

   Error during command line generation

   Reason:

   Unknown target

Hello @HBujanda,

We shared this information with the appropriate team.

We'll get back to you as soon as we have more information or a workaround.

Thank you for sharing this error.

I mates,

While I wait for the fix to be able to build the firmware image for the CortexM0,

I've been reading the documentation on how to download the (once I have it) to the CortexM0 core.

But I dont have an entry for the cortexM0 at /sys/class/remoteproc

I've the one for the cortexm33:

root@stm32mp2:~# cat /sys/class/remoteproc/remoteproc0/name
m33

But not for the cortexm0:

root@stm32mp2:~# ls -al /sys/class/remoteproc/
lrwxrwxrwx 1 root root 0 Dec 18 09:36 remoteproc0 -> ../../devices/platform/ahb@1/0.m33/remoteproc/remoteproc0
root@stm32mp2:~#

I've flashed the images described from:

https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP2_boards/STM32MP257x-EV1/Let%27s_start/Populate_the_target_and_boot_the_image

Which selects FlashLayout_sdcard_stm32mp257f-ev1-ca35tdcid-ostl-m33-examples-optee.tsv

root@stm32mp2:~# uname -a
Linux stm32mp2 6.6.48 #1 SMP PREEMPT Thu Aug 29 15:33:59 UTC 2024 aarch64 GNU/Linux

In a second step, reviewing the instructions at https://wiki.st.com/stm32mpu/wiki/How_to_use_the_Cortex-M0%2B#Memories_RIF_configuration_example

I've installed the linux kernel source code, make sure that all the pieces described there like having  STM32_M0_RPROC in the defconfig and some other entries in the device tree... build the kernel image and dtb and flashed to the module.... 

With same result: the entry for /sys/class/remoteproc/remoteproc1/firmware is not available.

Any hint?

Thanks in advance, Hector.

Hi @HBujanda 

Could you use the  FlashLayout_sdcard_stm32mp257f-ev1-optee.tsv instead ?

We'll get back to you regarding the project. We are currently reviewing the application internally.
