Flashing with nRFjProg

[pavan]

Hello All ,

I was Using nRFgo studio for flashing chipsets , now we are asked to use nrfjprog for flashing , i have downloaded the command line tools . but issue i am not getting how to start and how to program the SOC's using nrfjprog ? can anybody suggest me basic initial steps for programming using nrfjprog ?

For the first time try to execute:

nrfjprog -i

It should list all devices You have connected.

To program devices You have to point proper family (nrf51 or nrf52) with -f switch. To program for example nRF52832 try this command:

nrfjprog -f nrf52 --program HEXFILE_PATH --sectorerase

Remember that nrfjprog does not provide reset after program procedure. You have to click reset button or perform:

nrfjprog -f nrf52 --reset

Try also nrfjprog --help to know more :)

Hello Thanks for information.

Can i flash the softdevice merged firmware using nRFgo studio?

[kl-cruz]

I have never done it, but only if hex file has valid addresses then everything should (or rather has to) work well. Nrfjprog has no logic about programming softdevice or software. It just sends image to nRF microcontroller

Thank you sir.

And also how and where to install RTT terminal to figure out the unicast address of the Thingy. ?

You welcome. Oh, RTT is not question for me. I think someone else could help You with that question
