Problem to flashing immage to STM32MPF-DK2

[MMarc.11]

I cannot load the image into the SD card of the STM32MP157F-DK2 board.

I set the switches to OFF

I start the board that starts in BOOT FOR FLASCHING (only the LD4 led is on steady red)

Through the terminal or graphical STMProgrammer I start the download of the image (file: FlashLayout_sdcard_stm32mp157f-dk2-trusted.tsv)

It loads Partition ID 0x001 correctly, finishes loading Partition ID 0x003, then the board exits the BOOT FOR FLASHING mode (the blue LD8 LED lights up and the LD6 LED flashes red) and the software returns to me Reconnecting the device ...

Hi @MMarc.11​ 

Blue led mean uBoot started, and led6 flashing is probably an USB Type-C compliance issue.

To confirm, could you share the board Console log (available thru ST-Link VCP) ?

[MMarc.11]

and after the timeout time you add this:

 10:37:42 : Error: Unable to reconnect the target device: time out expired

 10:37:42 : Error: Start operation failed at partition 0x03

 10:37:42 : Error: TSV flashing service failed

 10:37:42 : Warning: Connection to device 0x500 is lost

 10:37:42 : Disconnected from device.

if instead I press reset and reconnect the cycle repeats itself indefinitely

Hi @MMarc.11​ 

I was meaning the UART console log using a serial terminal on STLink Virtual Com Port.

This is an example on Linux Ubuntu PC : https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Let's_start/Execute_basic_commands#Serial_terminal

On W10 or W11 it is very similar, you could use any terminal application like putty or teraterm or else.

Setup is 115200,n,8,1

I solved the problem, in the logs it showed me the supply current was too low.

Thank you
