    • OpenOCD where to set SWD speed?

    Posted by admin@micro-nova.com on 2016-02-03 23:41

    Hello All,
    I have a custom board with a STM32F030R8T6 processor, I am debugging using a ST-Link V2-1 on a nucleo board. For some reason I am only able to connec to my board at speeds up to 480 KHz using the ST-Link app. OpenOCD appears to always attempt to connect at 950 KHz and therefore always fails to connect. How do I go about requesting it connect at a lower speed?
    Thanks!
    Jason

    Hello Jason,

    You can use nucleo_f030r8.cfg placed in C:\Ac6\SystemWorkbench\plugins\fr.ac6.mcu.debug_1.6.0.xxxxxx\resources\openocd\scripts\st_board

    and add the following command
    adapter_khz 480
    after this line
    source [find target/stm32f0x_stlink.cfg]

    Regards,
    TarekB
