Hi,
I need to power my external board while debugging with the DK52. Therefore I don't use the VDD connection from the DK52, I only connect the external VDD to SH_VTG.
I use Pin19, as follows:
P19 External Board 3 (SH_VTG) <-> VDD 4 (SH_SDWIO) <-> SDWIO 5 (SH_SWCLK) <-> SWCLK 6 (SH_SWO) <-> SWO 7 (SH_RESET) <-> RESET 8 (SH_GND_DETECT) <-> GND GND PIN of DK52 <-> GND
Is this correct? Because I connected it like this, and it worked. I can program, debug etc. But I also destroyed my DK52 with this, because while I was working later I forgot to connect the supply GND of my external board to the DK52 and suddenly the DK52 was not working anymore. How can it be destroyed like this?
So to be sure, is this the right way to connect it?
