Hi!
I've been using PCA10028 for a long time and I had some bricking issues but I've managed to un-brick it with "nrfjprog --recover" and everything would work again.
I've beed developing some new software and I managed to brick it totally somehow. When PCA1028 is connected and powered on, power led of segger jlink is not lit on, it's off all the time. I can't do anything with the board, when trying tp use "nrfjprog --recover" it says "ERROR: There is no debugger connected to the PC." Seems like software on nRF51422 is crashing and holding the on board j-link in some weird state(or something like that...)
I can press and hold the boot/reset button and power it on which enters the bootloader (also PC shows that bootloader is active) but other than that, I can't do anything with it...
Help!
Thank you!
EDIT: I also have an external j-link, maybe I can unbrick the the chip on PCA10028 with it? Not sure where to connect the pins...
EDIT2: Managed to fixed it. This helped: devzone.nordicsemi.com/.../
