nRF52832 chip erase failed

[Anunnaki]

Hello,

After i uploaded a program on my nRF52832 i couldn't enter debug or reprogram the chip. This is the error i get when trying to erase the chip using Segger J-Flash Lite (I get the same error while trying to erase the chip using keil).

Any idea on how i can erase the chip?

I have figured out that in my while loop i left _WFE() from the example i used and that is probably the problem why i cant reprogram or erase my chip, is there a way to wake up the chip with hardware?

Then it seems that the debugger is not getting enough time to halt the cpu, try this using nrfGo studio and if it does not work, then most probably you have bricked your chip

what is the reason why the microcontroller is briked. I have the same problem, the reset pin is down continuously and there is no way to get it out of that state. With nfrjprog or nfrGO studio I can reprogram it. The only solution is to weld a new microcontroller, but there's no guarantee that it will be briked again.

normally the reason the microcontroller is bricked after programming it is that if you make it go to sleep too early after the wakeup without configuring a source to wakeup. You say that the reset pin is low continuously? is this a pin reset you are talking about? why is pulled low continuously?
