my Electron stopped working this morning and now only D7 led is on when I turn it on with its LiPo battery. When I plug it with the USB cable, the usb led also turns on.
I can’t understand why It stopped since I’ve been using this configuration for months. I read about it may be due to flaky power supply or bad contact though and that’s probably my case since some sensors’ leds flickered a bit.
I can’t get into DFU mode anymore and I also tried holding SETUP + pushing reset one time, as I read in another thread.
I also tried SWD using a Photon as programmer. I run it 10/15min ago but it didn’t prompt anything except for:
Do you have a dead device and wish to continue? [y,N]:y
Photon’s led is solid yellow/red while their D7 led are brighter now. Can I stop them?
I went to this topic (Dim d7 blue light and jtag config help for recovery) but links there are dead. @ScruffR
Can I use other photon as JTAG programmer? If not I have also a MCS-73 TTL USART and a chinese board I used as TTL/UART but with many more pins available (In the picture. HD: https://ibb.co/cQYzywL)
Can somebody help me? Tnks
