  • [SOLVED] Error during reflashing ST-Link


    Hello!

    I have tried to reflash St-Link by J-Link on STM32F407G-DISC1 board.
    But has got an error: Timeout: ST-LINK/V2-1 did not enter DFU mode. Now ST-Link is not detected.

    Is there any way to reflash st-link or j-link on the board by another board or so?

  • Hi,


    on the back of the board, you can solder to the pads SB2, SB4, SB6, SB87 and SB1 in order to get a debug interface which can be used to debug the ST-Link (a STM32F103).

    I just gave the ST Reflash tool a quick try with a STM32F407G-DISC1 board and "unfortunately" could not reproduce any issues.
    Flashing the ST-Link with the J-Link firmware and afterwards restoring the ST-Link firmware both worked fine.
