Hi.Is there a way to properly power off the board without using the console's poweroff command?Tried to press wake-up button for 10 seconds with no effect...Regards,Vlad.
We have custom SOM which has been designed with STM32MP157C.We are using the OpenSTLinux 3.0.0 as of now as the distribution running on it.In case of LAN PHY interfacing we are using LAN8720.There is a strange behavior , upon I can see the below mess...
Hi,I have some doubts about how I could sample from the ANA0/ANA1 pins of an STM32MP1 CPU from inside the M4 firmware via HAL. I would like to programmatically switch between these two pins.Sampling from ADC_CHANNEL_0 seems to work, so I guess it is ...
I am trying to customize the boot script which is used to boot my STM32MP157 Avenger96 board. I want to include some u-boot variables and alter the boot process.Current boot script:if test -n "${distro_bootpart}"; then setenv partition "${distro_bo...
