Hi,
Just today my J-link EDU mini - NRF52 donlge combo stopped working. I do the following:
1. nrfjprog.exe --recover
2. nrfjprog.exe --eraseall
3. I use J-Flash lite to program the bootloader for NRF52-Dongle
Normally now the device should be available for programming from the uVision software. Now I can program, there are no errors, but after programming, the device is silent. When I take it off the usb port, and disconnect the debugger, and connect the dongle back in - it's in the bootloader mode (i think) - the red led is slowly blinking.
To make the program work I have to start the nRF Connect - Programmer and transfer the hex file onto the device manually. Then it works.
If I try to program the device from the uVision again or start a debug session, the device goes back to being silent (red led blinking after removal and reinsert to usb).
Also sometimes when I reconnect my RTT viewer on an already working app it also causes the dongle to go to the "red blinking" mode. But not alwayd. Go figure.
There was no physical damage to either dongle or the debugger and it all worked perfectly until today.
Can I try anything to fix it? Is something permanently broken?
I don't have another set (dongle+debuger) to play with and find the faulty elelement :(
