On DK2, using devmem2 on linux I read that GPIOH->MODER/ODR (0x50009000/0x50009014) are all zeroes. The same for GPIOA. OTOH some other things can be read out like RTC clock settings. Is there a way to read the GPIO registers?
As stated in the title, I'm having trouble getting the ST-Link microUSB port connections to enumerate on the PC (Linux). I have two of the dk2 boards, and they have the same behavior. The only way they enumerate on the host is through the DFU mechani...
So it looks like Uboot supports /boot/extlinux/extlinux.conf boot menu file on STM32MP157-DK2 board? But does it support FDT entry used to specify device tree file to use? Or I have to rebuild the kernel anytime when I want to make small changes to d...
