I’m trying to extend the DAP-Link firmware on the Particle Debugger to support flashing my other devices but i don’t know which HIC to use since the GD32F103CBT6 controller on the debugger doesn’t seem to be supported by the DAP-LINK source code of arm-mbed.
Have you implemented your own support for the GD32F103CBT6?
My apologies to hack into this thread, but thought use context of the discussion.
Like you just suggested to @Bladeking, I did checked-out and built the DAPLink, and tried to flash the .bin file’s of all variants of k20dx_bl* and k20dx_if*, but none of them made the device to get back into interface mode, but your firmware, always works perfectly
