How to debug what's behind a system reset because of watchdog? I tried using dynamic debug and add stm32_iwdg.c file to print debug output, but that didn't give me more info, just some pings. So what can be reason for watchdog reset? We have program ...
I found no STM boards on OSADL platform (www.osadl.org). Why ?
Hey there, I am new to STM32MP1 and this forum has been a great help. During the last week I am trying to understand the OpenAMP between the M4 and A7. The ttyRPMSG makes things quite straight forward for the M4 part. When going to the linux part, us...
I create a process A to communicate with M4, another process B every 2 min will be calculate some data cost 230ms. in this inteval, process A cant use OpenAmp to send cmd to M4, until process B complete the calculation.
