I am trying to program my custom board with Nrf52832 chip on it, by using nrf52 Dk as Programmer. I have rechecked the Hardware Connections everything seems to be OK. I still have a feeling its a Software Problem. I tried writing this in my command Line

U:>nrfjprog -f NRF52 --recover

Recovering device. This operation might take 30s. ERROR: Recover failed. Please make sure that the correct device family is given ERROR: and try again.

U:>nrfjprog -f NRF52 --eraseall

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.

This seems it cannot DK access JLink to my Customboard at first instance but when i use JLINK command line i can easily connect with the Custom Board as shown in window below and at the same time when i say erase in Jlink CMD Line it says " Failed to prepare RAMCode using RAM". "Erase returned with error Code -1"

Does this Show any relevance to what can be wrong in Programming or the Chip itself?

Hi, Did you try the command with the --log argument? Can you updated your question and attach the log file?

[kunal]

i recently updated my question with Log data

[MartinBL]

Have you been able to program the board before or is this the first time you try to do anything with this chip?

There is a new version of nRF Command line tools (v9.7.0). Can you try that?

[kunal]

Hi i have the latest Version of Commandline. Sorry for late Reply. Actually everything is fine with the Current measuring Pins P22. I wanted to ask you. can you please explain me why is th error showing "JLinkARM.dll ReadMemU32 returned error -1". does that mean anything. Also I have 32 Khz Crystal with 2X 10pf capacitors around it. Is this value of Capacitor right and is it effecting the Programming ports?

[MartinBL]

What does the current measuring pins have to do with this? The -1 error is a generic JLink error. It could be caused by a lot of things, but it is most likely a connection issue.
