Hi
I'm currently working on the 10028 DK board, which was working flawlessly until I used the J-link RTT Viewer, and pushed the IF BOOT/RESET-button. Now, when I try to flash the MCU I get this in Keil:
*JLink Info: Device "NRF51422_XXAC" selected. JLink info:
DLL: V5.12f, compiled May 17 2016 16:03:35 Firmware: J-Link OB-SAM3U128-V2-NordicSemi compiled Nov 14 2016 16:58:29 Hardware: V1.00 S/N : 681151478
**JLink Warning: RESET (pin 15) high, but should be low. Please check target hardware. ***JLink Error: Communication timed out: Requested 20 bytes, received 0 bytes ! Could not read hardware status! Error: Flash Download failed
- Target DLL has been cancelled
I've tried to update to the newest J-Link bootloader, with no luck I've tried to recover the device as explained here, but get this output:
nrfjprog --recover --family NRF51
Recovering device. This operation might take 30s. ERROR: Cannot connect to any nRF device. Please make sure a device is ERROR: connected to the debugger and supplied.
Using nRFgo Studio, does not work either, nRFgo is crashing if i try to connect to the debugger.
Also, I know that the MCU is still running because the LED 1-4 are flashing as expected.
