Please check STM32MP157F-DK2 no function issue after STM32MP157F-DK2.
#1. After receiving the STM32MP157F-DK2 board, I connected a 5V/3A Type-C Power Adapter to CN6 and verified Linux boot and operation. LCD operation.
#2. Updated the Linux image on the SD card using STM32Cube Programmer on a Windows PC.
Following the procedure in the link below, successfully updated the Linux flash image to the SD card using FlashLayout_sdcard_stm32mp157f-dk2-optee.tsv via STM32Cube Programmer on the Windows PC.

#3. Turn SW1 BOOT0 and BOOT2 back ON, connect the USB Cable to the ST-LINK (CN11) on the PC, and connect the 5V/3A Type-C Power Adapter to CN6 to boot the stm32mp157f-dk2 board.
#4. UART logs output normally, but the message "ERROR USB TYPE-C connection in unattached mode" appears and Linux does not boot. - The same Type-C Power Adapter used in #1 above was used.
#5. Approximately one hour later, the stm32mp157f-dk2 board became significantly hot, and Linux still did not boot.
#4. After sufficiently cooling the board, connected the USB Cable to the PC via ST-LINK (CN11), connected the 5V/3A Type-C Power Adapter to CN6, then
No UART output from CN11, POWER IN LD2 LED GREEN, LD4 LED RED, all other LEDs OFF. No Linux boot.
