Nrfjprog Error : the system cant find the file specified

[Tiger]

Hello ,

I'm trying to change the major and minor values on the nRf51 DK . I installed the command line tools and was able to use the following command to identify the serial number of the connected device : nrfjprog -i which work fine and returns the serial number .

However , when I use the following command to change the major and miro values of the beacon : nrfjprog --snr <681184936> --memwr 0x10001080 --val 0xabcd0102

I get the following error : The system cannot find the file specified.

any ideas on how to resolve this ? I'm using nrf51822 with the S130 installed on it and it is running the beacon example program .

Are you able to run nrfjprog -i from any directory? Can you upload an image showing the error, or an exact copy of the terminal output?

I seem to be facing a similar problem.

Unfortunately, I am not getting any output from `nrfjproj -i` with an `nRF52840` connected to the computer. Instead, I obtained the serial number from the `Programmer` in `nRF Connect for Desktop` and I tried the following command:
```
   $ nrfjprog --snr CD21B872F31E --memwr 0x10001080 --val 0xabcd0102 --log
   ERROR: Argument provided has a wrong value. Memory access not aligned, value
   ERROR: outside of range or similar.

```

I do have `nrfjproj` installed, though:
```
$ nrfjprog -v
nrfjprog version: 10.23.2 external
JLinkARM.dll version: 7.92o

```

Could it be that I still need to configure something in nrfjproj?

Please post your question in a new ticket, this is soon 7 years old.

If nothing is listed by "nrfjprog -i", there is no J-Link debugger connected to the PC. Note that only the DKs contain debugger, not nRF52840 Dongle or other boards. The serial number you listed is not a J-Link serial number, but it looks like it could be a USB serial number for a bootloader.
