We are a connecting a sensor to M4 side and reading the data through UART7. UART7 is enabled for M4 by modifying the Linux Kernel Device tree and TF-A .dtsi files. Device tree file for TF-A is generated through STM32CubeMX. and Placed the generated f...

Hi Olivier,Do mean to suggest to modify the given dts file(stm32mp157c-dk2.dts) with cubeMX generated file? I tried a different way. Placing the cubeMX generated dts file in the dts folder and adding the name in Makefile. But that seems not be workin...

Hi Olivier,There are multiple ways given to build the dts files. Earlier I used Developer Package method.Based on your feedback on DMA2 not being in m4 peripherals, now I chose to build Distribution package method.Sorry for confusion.How did you bui...

Hi Olivier, Thanks for the feedback. I am currently building a new image with generated device tree files. ( I am following a method given in How to Build your machine) I am assuming you also did the same thing. I didn't do the code...

Hi,I have sent the dmesg log file. But didn't do the logging in the code.If you have any sample project with OpenAMP and a peripheral interface, please provide us the code.Best Regards,Upendar
