Hi,I am debugging the STM32MP257F-EV1 board with a debugger via JTAG/SWD. The kernel version is 6.1.82.Since the A35 cores are in break state/stopped during debugging, I want to disable the watchdog timer on U-Boot/Linux.I have tried the following wa...
We have a custom STM32MP157 board running Linux that is not booting over eMMC. The STM32MP157 image boots from SD card on SDMMC1 but not from a Toshiba THGBMNG5D1LBAIL eMMC chip connected to SDMMC2. We have confirmed the Boot pins are correct, and th...
Hi i am struggling in how to boot from the EMMC not from the SD card , i used the custom board where my emmc is connected to SDMMC2 port , i did changes into the device tree i enable the sdmmc2, but i do not know how to boot from the emmc ?,actually ...

Hello,I am using the STM32MP257x-EV1 board with version 2022.10 of u-boot-stm32mp (with patch 0001-v2022.10-stm32mp25-beta.patch from commit dc5d7824 made on April 12, 2024).When compiling u-boot + stm32mp257f-ev1.dts, only the eth2 interface is func...
I'm still trying to get a fully error free bootup on the stm32mp151 based board. I'm using ST git's for the bootstages and kernel/rootfs are build using the ST yocto layers.But because i'm unsure which are actually errors and which are just warnings ...
We have a custom board based on STM32MP157C-DK2. U_boot shows a splash image(logo). Then U-boot starts the kernel from a fip image. I the same fip image there is a ramfs partition in cpio.gz format which is used as rootfs by the kernel. When kernel s...
Hello,i'm currently trying to boot a custom board which has the bare minimum of STPMIC1, SDRAM and USB closely resembling the STM32MP15-DISCO evaluation board except on power delivery (VBUS from USB-C is switched via STUSB4500 but _not_ connected to ...
