RE: How to upload Bootloader HEX in nRFGO Studio

That should work if you remember to erase the chip before you program (i.e. nrfjprog --eraseall before nrfjprog --program NRF_CDC_DFU.hex).

Another option is to do the steps in one command by adding -f & --chiperase if you want to erase all available user flash (including UICR registers) before you program the hex file. By adding -f (family), the command should execute quicker.

nrfjrprog -f NRF52 --program NRF_CDC_DFU.hex --chiperase

See this link for more info & command options.

I found it.

In the cmd window
[c: \> nrfjprog --program NRF_CDC_DFU.hex] to make it easy to upload.
Do you mind if I do this?

I have confirmed that Softdevice, Application and DFU are all uploaded via nrfjprog --program.
