I need to program 8 boards with SWD interface device but I have one programmer with 4 channels.
Is it sufficient if I connect SWD lines in parallel permanently to all 8 boards and just toggle the power in groups? First four powered on, then program. Switch off first '4 group' and power on the 2nd '4 group(5-8)' and program 2nd group?
Do I need to keep the RESET low for 2nd group when 1st is being programmed or power on/off is enough?
