Hi,

Yes, you can perform "nrfjprog --eraseall" command to erase all and "nrfjprog --program new.hex --verify" to program a new image with the nRF Command Line tool.

Hey Amanda,

We are currently working on a test version of our device. I would be happy to erase everything on the device and install new firmware. Is that possible via SWD?

Hi,

Do you mean to perform the nrfjprog --recover command over SWD? It needs to install the nRF Command Line tool. However, the recover command is used to Erases all user available non-volatile memory and disables the read back protection mechanism if enabled. It would not work as you expect to put the device into bootloader mode.

Are you working on DFU? With nRF5 or NCS?

Amanda
