DFU trigger - reinstall the out of the box demo on the PCA10059

[Michael]

Hello,

I have accidential removed the DFU bootloader on my PCA10059 dongel..... is there an image that I can write to the dongle to get it back into its out of the box condition (with a woorking DFU trigger)?   Note, I have a JTAG programmer that I can connect to P1 on the underside of the dongle to upload any require programming opperations.

Cheers

Michael

Hi Michael

It seems like this file doesn't work building directly on Segger, we just use this command: 

nrfjprog -e && nrfjprog graviton_bootloader_mbr_v1.0.1-[nRF5_SDK_15.0.1-1.alpha_f76d012].hex --reset

This should work as long as you have the nrfjprog command line tool installed.

If you still run into problems, try going through the "Recover after an accidental UICR erase" instructions as well.

Best regards,

Simon

The nrfjprog command seems to throw an error (I have shortened the name of the hex file to make typing quicker)

Note: I can use nrfjprog --help withot any problem 

Other simple nrfjprog commands seem to fail also
