Can not Flash STM32MP157a-dk1. with CubeProgrammer, and StarterPackage Image. First 2 files download ok, then get "Reconnecting the device...", and it never reconnects. Windows10 drops the USB-DFU device. Get Error:TSV flashing service failed. How to fix?

Hi @MDoxb.1​ ,

please provide log files

• from CubeProgrammer
• taken from the UART Console (Virtual Com Port on STLink connector).

Check that you are using the right TSV for the board (should be "FlashLayout_sdcard_stm32mp157a-dk1-trusted.tsv")

Try using command line (run it from images\stm32mp1 folder) such as :

"%ProgramFiles%\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" -c port=usb1 -w flashlayout_st-image-weston\trusted\FlashLayout_sdcard_stm32mp157a-dk1-trusted.tsv

Please also confirm you did not have a Virtual Machine opened which could 'take' the W10 USB port when uBoot is reconnecting.

Regards.

Attached is the output of the console (TeraTerm), and the log from the Cube programmer.

I am using the 157a-dk1 TSV file.

My system does the same thing when using the command line.I have even tried to 'Disabled' the Windows 10 Power Option to selective suspend USB.I've even installed CubeProgrammer on a VirtualBox/Ubuntu system and the same thing happens.

When Programmer is "Reconnecting the device ...", Windows 10's Device Manager updates its screen and the USB device "DFU in HS Mode @Device ID/0x500,@Revision ID/0x0000" disappears from the listing. After all the Errors get reported, the DFU device comes back.

And here is the log

Hi,

according to your uBoot log, your 5V power supply is not compliant to USB Type-C standard (usually CC lines not or badly connected).

This will stop the Starter Package uBoot with red led blinking.

See https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Let%27s_start/Populate_the_target_and_boot_the_image

So your issue is not due to your PC setup.

Solution could be either :

• Use a power supply driving correctly USB Type-C CC lines (see https://community.st.com/s/question/0D50X0000Bftr1ySQA/power-supply-for-stm32mp157cdk2)

or

• recompile starter Package uBoot to skip the CC lines check (see https://community.st.com/s/question/0D53W00000qvZllSAE/my-stm32mp157fdk2-is-powered-by-5v-3a-psu-but-at-the-boot-up-time-always-it-displays-the-warning)

First option is straightforward.

Regards.

I switch power supplies and now I am able to Flash the SD Card.

Good = Ultranet CX65UC002 Ultron GaN 65W Type-C PD Charger

Bad = CUI Inc. SWC15-S5-NB Wall Mount AC Adapter 15W 5V 3A

Thank you
