    Hello,

    You can try to activate internal Rom Loader with BOOT0=1 and BOOT1=0 before Reset. So your firmware don't start and there is no remap of JTAG lines.

    If you connect nSYSRST out, you needn't control the BOOT0/BOOT1. the programmer like Jlink can avoid the remap by you code by control nSYSRST.

    I does so in my handy programmer--EP868, a standalone programmer used for STM32, by SWD port.
