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?

terminal output

I also tried the following which includes the family but got the same error :

nrfjprog -f --snr <681184936> --memwr 0x10001080 --val 0xabcd0102

I managed to change the major and minor by modifying the code in the KEIL example but I would like to know why the nrfjprog is not working fully because it looks like its used alot in thedocumentation

Try removing the <> around the serial number and the family parameter:

nrfjprog -f nrf51 --snr 681184936 --memwr 0x10001080 --val 0xabcd0102
