I want to know the difference of device tree compiling the with the Developer Package and Distribution Package.
I understand that when I create my own machine, I can create device tree by following 2 method.
Method 1) Building device trees with Developer Package (separately from bitbake)
This method is described in following Wiki page.
https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_Package
Method 2) Building device trees with Distribution Package (included in bitbake)
This method is described in following Wiki page.
https://wiki.st.com/stm32mpu/wiki/How_to_create_your_own_machine
When I checked the operation with the device tree created by above two methods, the behavior was different even though the device tree source before compiling was the same.
Specifically, with device trees build with Developer Package I can use remoteproc to exchange data with Cortex-M4, but with device trees build with Distribution Package I can not use remoteproc to exchange data with Cortex-M4.
If I want to Building device trees with Distribution Package (Method 2), is there anything else I have to do other than what is written in above wiki page?
For example, in Method1, I have to execute following command etc. Are these commands required for Method 2 too?
PC $> for f in `ls -1 ../../sources/arm-ostl-linux-gnueabi/linux-stm32mp-*/fragment*.config`; do scripts/kconfig/merge_config.sh -m -r -O $PWD/../build $PWD/../build/.config $f; done
Best Regards.
