Thanks Tomchy for the tip and the makefile. Will try it out.

I'm not sure you have to convert anything to *.bin files. JLinkExe (for sure in V4.98c version) has also command called "loadfile" which accepts *.hex files too. If you want to - you could also adjust makefile, which was created by my team for IoT contest: gity.sznup.se/.../makefile It's based on Nordic's makefiles and has some extensions like SDK path variable, board settings etc. Currently it works only with nRF51 boards.

:) Thanks for looking into this Hung. So you say that we should convert the complete Softdevice S110 version greater than v7 hex to bin with arm-non-eabi-objcopy and then program this with loadbin softdevice.bin 0? This gives me the error mentioned in the question. If it works for you I'll double check everything. I'm not looking to program a bootloader by the way.

The new Softdevice from v7.x doesn't need data to be written to UICR. So you don't have to program UICR binary if you simply want to flash application and softdevice. Just have to loadbin each of them. Mind the start address of the application.

But if you want to flash bootloader, you would need to write to UICR. What you need to do is to open the bootloader hex file and copy the data at the end of the hex file where we write to address 0x10001014. Something like this:

:020000041000EA
:0410140000C0030015
:040000050003C0C173
:00000001FF

And create a separate hex file, then you can convert it to bin and flash to UICR using loadbin filename.bin 0x10001014

Ha ha, didn't know that the answer in that case was actually from you :) I guess the issue now is that the UICR.bin is not generated. Give me few minute to check what could be the solution here.

@PrithviRaj: I'm sorry that I'm expert in Linux. But could you try to follow this ? : https://devzone.nordicsemi.com/question/44412/firmware-flashing-using-jlinkexe/

We currently don't have support for gcc on Linux, but I was thinking that it shouldn't be too tricky to port.

These are the make targets available in the latest SDK 9.0.0 -

## Program device
.PHONY: flash
flash: $(OUTPUT_BINARY_DIRECTORY)/$(OUTPUT_FILENAME).hex
	nrfjprog --reset --program $(OUTPUT_BINARY_DIRECTORY)/$(OUTPUT_FILENAME).hex

.PHONY: reset
reset:
	nrfjprog --reset

.PHONY: erase
erase:
	nrfjprog --erase

But nrfjprog being a Windows program I can't use it in Linux. Yes, I was using JLinkExe tool by SEGGER for Linux. Is there GCC support for Linux, not only Windows by NordicSemi? When I upgraded from 6.0.0 Softdevice S110 to 8.1.0, I am not able to use the same method that I was using earlier, similar to github.com/.../nrf51-pure-gcc-setup

@PrithviRaj Narendra : Please use the latest SDK which we support GCC out of the box. The github example is very old. You can download the SDK here.

How do you flash the hex/bin file ? I assume you have the Jlink tool for Linux ?

Earlier the softdevice hex file was used to generate two bin files, one for the main part and one for the UICR part using arm-non-eabi-objcopy. Now I think after SoftDevice S110v7 there is no UICR part in Softdevice. I'm using Linux, so I won't be able to use nrfprog.exe Could you check if the make targets in this repo works - github.com/.../nrf51-pure-gcc-setup Thanks!

@PrithviRaj Narendra: What do you mean by "generate only one bin file from the softdevice hex file" ? Do you have trouble when flashing our example's compiled hex file ? Could you try using nrfjprog.exe to flash the hex/bin file ?
