Hm, it's indeed plausible that one of your components is faulty. I guess you can try to check the 3.3V rail and the EPD voltages, but ideally you'd have an Oscilloscope to see how the TPS65185 behaves. Or some diode in the switchover circuit is fried, etc. Hard to tell from just the logs :/
I've been developing with the V7 for a few months without a problem using a USB-c connected to my laptop, now that I had my prototype working for the first time I tried to connect a 3.7V battery while connected to the usb-c, I could see the RED LED lighting once I connected the battery meaning is charging, the problem is that it got stack in that mode, the battery connection was not very reliable and it got connected and disconnected a couple times, with the red led lighting on and off. Then the red led stayed on even when I disconnect the battery.
If I disconnect the USB-C and connect the battery the board seems to work since the display gets updated.
But with the USB-C the red LED always stays on even without battery, I can re program the board, but the board does not seems to work , on the
idf.py monitor
I either get nothing after I do aepd_poweron();
(on the dragon demo) and on my program I get an infinite restart loop. So I have lost any capability to debug my code on the boardIs there anyway I can fix this problem? Maybe one of the components got fried? Any guesses?
This is the loop itself on my program:
The logs on the dragon demo:
And it just stays like that forever
