Ohk. I have raised query to Nordic. I will post here if I found anything substantial.

Unfortunately not, I just have a jumper to cut the power once I finish programming it.

Hi,

I am facing same issue.

I have combine hex file of bootloader + application (SDK 14.1.0) + softdevice (S132 5.0.0).

When I program it with nRFgo Studio, after programming, device start executing code but it hang after around 1 to 2 second. However, after power cycle, device starts working normally.

In addition, when I remove watchdog init code from application. It is working fine even after programming. So I am suspecting issue is related to watchdog of nRF52832.

Have you found any solution for this?

Doing a nrfjprog -r -f NRF52 does unlock it

@Dajgoro: Please try to do a pin reset with nrfjprog.

I set the timeout to fairly long. I tried with 10 sec. Also it can happen on NVIC_SystemReset() but I have to test that more to be sure.

Hi Dajgoro,

I suspect that when you program the chip using Keil, there is a short period between programming and verifying that can cause an issue because the chip can run for a short period of time there. My suggestion is to trigger a reset using nrfjprog after your program with Keil if you don't want to do power reset. Or simply use nrfjprog to program the chip.
