Hi,
I'm using stm32mp157a-dk1 and I would like to use rpmsg_sdb for exchanging data buffers with the coprocessor (https://wiki.st.com/stm32mpu/wiki/How_to_exchange_data_buffers_with_the_coprocessor).
I built the image for the A7 following the "STM32MP1 Distribution Package" tutorial without problem (https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package#Flashing_the_built_image).
But in the dev folder I can't find the rpmsg_sdb device.
Is there a prebuild image for A7 with this driver?
If not, how can I add the recipe rpsmg-sdb-mod Yocto recipe to the image of the distribution tutorial using bitbake?
In case, is there other ways to get the device rpmsg_sdb?
Thank you in advance.
Best regards,
Andrea Segalla

Dear @Community member ,
Thanks for the reply.
I tried this morning to add the layer meta-st-stm32mpu-app-logicanalyser following the tutorial you suggest to me but it returns me errors in the last command:
bitbake-layers add-layer ../layers/meta-st/meta-st-stm32mpu-app-logicanalyser
the errors returned:
NOTE: Starting bitbake server...

Do you have the same problem or probably I made some mistake?
Thanks in advance.

Hi @ASega.1​ ,
The add-layer steps works properly at my end.
Double check all the procedure and eventually retry on a clean environment.
