how to install python submodule on stm32mpu

[NashHsu]

Hi 

I used pip3 install python submodule.

The submodule inclued xxx.c files.

The install processing be use 'arm-ostl-linux-gnueabi-gcc' compiler tool, The processing be fail.

I can't find gcc-arm-aarch32-arm-none-linux-gnueabi tool for The STM32MPU157-DK2.

I find out tools are 'gcc-arm-aarch64-arm-none-linux-gnueabi', But it can't use on the STM32MPU157-DK2.

I use STM32-SDK provider comliler tools, it is don't working too. 

The other question,

Hello @NashHsu 

The image installed on STM32MP boards doesn't contain any toolchain nor *-dev or *-src packages hence the errors you may face when trying to install python modules which need to be built on the board.

To add the python module which requires a compilation, you need to create the corresponding recipes into your Yocto environment.

To add a new recipe, please follow this wiki page: https://wiki.st.com/stm32mpu/wiki/How_to_add_a_customer_application

To build the recipe for your Python module, you can use the pipoe utility (https://pypi.org/project/pipoe/) from your host PC:

$> pip3 install pipoe
$> pipoe -p <your python module> --python python3

And then just copy the generated .bb file to your layer.

For your next question, I don't have any idea. Please open a new thread for this specific item so the community will help you.

Hi @NashHsu 

Yes, you can install a python sub-package into your image. Once you have written the recipe for your python module, please refer to this wiki page to add it to your image: https://wiki.st.com/stm32mpu/wiki/How_to_add_a_customer_application#Quickly_add_the_recipe_to_an_image
