Failed to firmware upgrade ST-LINK firmware on STM32MP157F-DK2 board using STM32CubeProgrammer version 2.12

[SThon.1]

Hi,

I am using STM32CubeProgrammer version 2.12 running on Windows 10 to connect to the STM32MP157F-DK2 board ST-LINK connector CN-11.

I managed to connect and when I click "Firmware upgrade" the STLinkUpgrade 3.4.0 window opens.

However, when I press "Open in update mode" I get the error message:

Error connecting to device ST-LINK/V2-1 (error 0x3); check USB connection and refresh the device list

At this point the connection is dropped and I have to connect again.

I also noticed that the "Current Firmware" was not listed as I expected from my experience of upgrading the ST-LINK firmware on other NUCLEO and DISCOVERY boards.

Maybe the current version of STM32CubeProgrammer doesn't yet support the STM32MP157F-DK2 board ?

Any help would be much appreciated.

Kind regards,

Steinar

Hi @SThon.1​ ,

could you please try without connecting to the target.

Note that STLINK within CubeProgrammer is useless with STM32MP1 devices as Flash programming must be issued using USB or UART(not viable due to size to be loaded). see https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Let%27s_start/Populate_the_target_and_boot_the_image.

STLINK is only there for VCP (console) and debugging using CubeIDE.

Alternatively you could also update to latest STLINK FW using dedicated tool: https://www.st.com/en/development-tools/stsw-link007.html

I got it to work when not connecting to the target as you suggested and was able to upgrade the ST-Link firmware on the board.

Thank you for the quick reply!
