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.

For one project we would want to use only de M4 core of the SM32MP157 MPU. We want this because we have no time to learn how to develop the whole application using linux and the whole potential of the MPU, but we would want to have the hardware ready...
If I order from st, how many days does it usually take to get to Korea?I placed an order last week... it's only for processing.
