  • [ABANDONED] Minimal JTAG pins

    we need a minimal number of pins to program the STM32H7xx (ARM M7) using the JTRACE/JLINK probes. I was able to program the processor successfully with just SWDIO, SCLK, GND and VTH (3.3V) connected. I'd like to eliminate the 3.3V to save space, but not sure if there is a way to force the probe to work that way. Is there something in the setup that I can change to make it work?
