Hi,
I bought the J-Link supply adapter from digikey to use with my J-Link ULTRA+ on boards that do not expose the VTREF (3.3V) on the debug header.
However it does not seem to work like I thought it would, the debugger does not recognize any device, the LED on the Supply Adapter does not light up and there is no voltage on the Vsupply pin of the J-Link ULTRA+ with or without the Adapter (measured with a multimeter). The J-Link ULTRA+ works if I test on a board that does expose the VTREF (not using the J-Link Supply Adapter).
Is there anything I have to do on my computer so that there is 5V at the V-Supply pin of the ULTRA+? I have tested multiple USB ports with no success.
