Hey Danilo,
thanks for replying.
I've got the 'real' debugger. I know it works because I have tried
programming another device with JTAG and it worked fine.
At this point all I'm doing is trying to connect to target with the ST-Link
utility on windows.
Yes the SWIO and SWCLK pins are correctly connected. I double-checked as I
was writing this just to make sure.
I tried your idea connecting the TVCC pins to 3.3V vias on the board but I
sent the board to some ring of death, so I hooked a seperate power supply,
set it to 3.3V, and connected the TVCC pins to that. I even connected the
NRST pin to the ST-Link's TRST pin.
Still nothing. I was begging for a JTAG connection to just appear on the
board after all this! :D
At this point having to connect the board like this just isn't feasible so
I'm back to just programming the board with DFSU.
Thanks anyway,
