I'm trying to connect SWD to a 11C22 M0 chip with crossconnect original + SWD adapter without any luck.
CPU appears to be running - I can erase / program it with flash magic
On CrossStudio, I get 'Cannot set debug register'. Explore window shows no devices..
Any ideas what I'm doing wrong? Are there any other pins I should be controlling to enable SWD??
Connections are (on the 10w SWD)
Pin1 = 3.3V
Pin 3/5 = GND
Pin 2 = SWDIO (pin 39 on cpu)
Pin 4 = SWDCLK (pin 29 on cpu)
Pin 10 = reset (pin 3 on cpu)
Also have an external 6MHz clock into the CPU, but I believe that this CPU will use its internal 12Mhz RC clock until told otherwise.
I've double checked cabling. I can see 4 bursts of SWD data using an logic analyser, but being single wire I can't tell where it's coming from.
