Solved, just bad luck, I got 3 broken module, the 4 is ok.
So it module's problem.
=======================================================
I am trying to flash "hello world" to my custom 52833 board, but failed. And I got this error.
PS C:\Users\canic\zephyrproject\zephyr> nrfjprog --program 'C:\Users\canic\zephyrproject\zephyr\build\zephyr\zephyr.hex' --sectoranduicrerase --verify -f NRF52 --snr 685691298 --log ERROR: [SeggerBackend] - JLinkARM.dll reported "-1", "An unknown error.".
I also try reinstall jlink, nrf, do on ubuntu, ant it all failed.
But if I flash to 52832dk or third party 52832 board (https://www.raytac.com/product/ins.php?index_id=82), it success.
That means my 52832dk's j-link is ok.(I think so.)
Here is my schematic, I use third-party module "MDBT42Q-512KV2" :
Custom board 528932dk
swclk p20 swclk
swdio p20 swdio
p20 gnd detect <> GND
p20 vtg <> 3.3vtg
Also I try pull up reset pin, but nothing change.
