I burn the FW to the chip using Nordic development kit connected by "Debug out" to JTag that is connected to the boardthat we work on.
we have used this setup for both our costum board and the 4520 EVB for a few monthes now.
in the last two days, two of our boards were bricked, while working on changes UART2, we are unable to flash/erase/recover two boards.
please see NRFJPROG log attached.Can they be recovered? What can be the cause for such problem? How can we avoid it?

[Jørgen Holmefjord]

Hi,

Can you try to tie the reset pin of the nRF52832 directly to VDD and then run "nrfjprog --recover" command? This has resolved some similar issues for customers before.

Best regards,
Jørgen

thanks

I tried it but unfortunately , It does not work on our case

[Jørgen Holmefjord]

Is the chip on the board powered correctly and at the correct voltage level? How are the connections from the Debug out port of the DK connected to the custom board?

[arik1]

1. re-checked the voltage- its working corrctly.
2. the last flashed SW is stilll running, but we cannot re-flash the board.
3. we use a regular 10 pin segger between  the ISP4520 EVB to the DK (please see attached schematic).
4. the flashing worked a few weeks , but in the last two days , 2 boards were bricked (they cant be flashed).ISP4520_TB_Schematic.pdf

[Jørgen Holmefjord]

If the supply is correct (3V), and the previously flashed firmware is running, the only suggestions I have is to run recover command in a loop, test with another PC, or test with another debugger (possibly a standalone J-Link debugger).
