Hi,
I tried to use external energy resources in order to test the system with unstable power. On the other hand, I also need to connect the pad with computer by USB port in order to get console output. I tried to remove the jumpers in J101 (for 3V3 and 5V), but I think it is still somehow powered by the USB port because the console showed that the system keeps running in a long time. I also removed the jumper for the super cap. Now the jumper eZ-FET and the main pad is only GND, SBWTDIO and SBWTCK.
I wonder what should I do to enable console output and the external power at the same time.
Thank you in advance!
