After linux bootup on STM32MP157C custom board with kernel build 5.4.31, I load and start M4 with remoteproc successfully, but every time when linux access uart8@40019000, M4 side firmware stopped, the two command i used to test is "echo 123 > /dev/t...
I am trying to record instruction traces on-chip via ETF on a stm32mp157a-dk1 board, but the data read from FIFO through RRD is always 0. During the debugging process, I found the value of ETM_AUTHSTAT is 0x08, which means non-secure non-invasive deb...
Hi everyone, hope everything is OK. We are trying to use the STM32MP157-DK1 board for a project, but we notices that the ST-LINK included in the board consumes current even if we are not using it. There is a way to disable the ST-LINK by software? o...
Hi I have list of unused pins need to configure as a GPIO, and some as a AF's, do we have any driver which shall facilated unused pins by default set pins state., we have in imx6 IOMUX which does that job in kernel., in mp1 i didnt find that.
