Hello ST team,I’m working on a custom board based on STM32MP135F SoC, with GigaDevice GD5F4GM8UExxG (512 MiB SPI-NAND) connected on SPI1 interface.I’ve successfully integrated this NAND flash in U-Boot and Linux (Yocto build), but the board fails to ...
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. 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:...
Hi,I'm working on enabling USB 3.0 support for the STM32MP257 in U-Boot and need a suitable driver. I’ve attempted to modify the U-Boot kernel driver to support USB 3.0, but I’m running into issues with the PLL configuration.The problem seems to stem...
I am connecting my STM32MP257F-EV1 board to rpi Hailo 8 board via Mini Pcie to M.2 key M adapter. The board is not getting detected even though clock and reset signals are coming properly.I am using the stm32mp257f-ev1.dts (default device tree) and a...
Hello all, I am following the following guide: https://wiki.stmicroelectronics.cn/stm32mpu/wiki/STM32MP25_Discovery_kits_-_Starter_Package In order to bring up a STM32MP257F-DK board and am running into a problem when I try to use the Programmer to f...
Hello everyone,I’m currently developing a custom board based on STM32MP151A, and I’ve successfully built my Open ST Linux (Yocto Scarthgap / v6.6) image using my own Device Tree generated from STM32CubeMX and further customized for our hardware.The ...
Hi ST Community,I’m using the STM32MP257F-DK board and successfully followed this guide: Modify, rebuild and reload the firmware Everything worked fine during the initial setup and firmware modification. Now I’m trying to flash a new image to the SD ...
Hello,we have product based on a STM32MP157 running Linux. The distribution is based on Yocto kirkstone and we are using a 6.1.82 Kernel. For the MP1s' GPU we use the open source entaviv driver that ships with this kernel. The device has a graphical ...
