nrfjproj ERROR: JLinkARM DLL reported an error.

[itiancai]

Hello .

I try to connect my JLink to my nrf51422QFAA cunstom board. And I use J-Flash to test ifg it can readback and it is OK. But When I try to use nrfjprog, I got some error.

Here is my command : nrfjprog -e -f nRF51  --log

And I got some error.

ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.

the content in log file is :

It hint my problem generate at GetSN phase.

Any idea?

Just in case. If someone else will hit it. Explanation :)

Chinese clones report "-1" (or 0xFFFFFFFF to be precise, but this is "-1") as serial number. And nrfjprog ( "libjlinkarm_nrfXX_nrfjprog" libraries, to be precise ) check returned serial for negativeness (assumption is that serials are positives and errors are negatives), and therefore assume that GetSN function returned error.

SEGGER flasher has no problem with those clones. So, if you need to flash, erase of whatever else, you can do it from J-Link programmer. If you need to use nrfjprog specifically, then you need to either patch those libraries (DLLs, SOs or DYLIBs) to exclude that check, or patch your J-link firmware.

Thanks for your summary. I midify the sn and it works.
