  • [SOLVED] ST-Link reflash to J-Link. VCP is not working properly. BUG ? (stm32F429I-Disco1)

    Hi,

    Data sent from STM32F429I-Disco1 to the computer - it works properly...


    Data sent from a computer to STM32F429I-Disco1 - is not working properly, is sent only a start bit frame rs232


    This is a bug in the firmware J-Link for ST-Link


    I use google translator....

  • Hi,

    @tkr: Sorry, we seem to have overlooked this thread.

    Could one of you provide us with a reproduction project for one of the boards listed in the Compatible Evaluation Boards list ?
    This would speed up reproducing / fixing the issue.

  • Hi,

    Board - STM32F429I-DISC1, 115200, 8n1

    os - Linux Mint 17.3

    In firmware J-Link TX output is an Open-Drain ? Why not Pull-Up or Push-Pull ?


    firmware ST-Link - sent from a computer to STM32F429I-Disco1 only one char "e" - is ok



    firmware J-Link - sent from a computer to STM32F429I-Disco1 only one char "e" - not ok



    Example firmware for STM32F429-DISC1 (messages appear only in Polish):
    Z002.elf.zip

    I use google translator....

  • Hi,

    this is an error on the website.
    We only tested the STM32F429I-DISC0 version of the board, but not the STM32F429I-DISC1 version.
    We just ordered a STM32F429I-DISC1 and will investigate this issue as soon as possible.

  • Hi Forum,

    the firmware has been updated in order to support the STM32F429I-DISC1 board.
    If the issue still persists when using the STLinkReflash Tool 161221 or newer, please open a new thread.
