Hello,I have developed a custom board using the STM32MP157DAA1. When I try to write the boot image, the process stops after writing fsbl-boot and does not proceed to the next step.I checked the output from the debug port and received the following lo...
Hello ST community,I’m an embedded software beginner working with the STM32MP257-DK board and OpenSTLinux (Yocto). I need help getting USART6 working on the external GPIO connector (PF13 = TX, PF14 = RX — CN5 pins). I have rebuilt device trees and co...
Hello. I'm trying to configure the otm8009a 800x480 display panel from the stm32mp157f-dk2 dev kit on the Seeed Studio's stm32mp157c-odyssey board.The issue is that by probing display with modetest -M stm I'm getting:failed to open device 'stm': No s...
Dear All,I have a total of 8 boards with eMMC from Alliance Memory. All of them boot from SDCard and work well. On 4 of them eMMC is detected correctly and boots fine with 50Mhz/8bit/ddr speed.4 boards are failing in exactly the same manner, that is:...
I am trying to drive a 5 inch 800x480 touch display from waveshare using my STM32MP257F-DK development board. My Linux distro is a custom one built using Buildroot via bootlin support.When running `modetest -M stm -c`, I don't get any resolutions pri...
