[SDK11][GCC][LINUX] Error 127 for nrfjprog [closed]

[Lalit Kumar]

Hi,
I'm using GCC with SDK11 on linux. I'm able to build successfully. When I try to run "make flash" or "make flash_softdevice", I get error nrfjprog command not found, error 127. I have double checked that nrfjprog is in my path, and I am able to flash the softdevice if I copy the command from Makefile to terminal in the same directory. I am using command line tools 8.4.0 64bit.
Any suggestion would be helpful.

Regards
Lalit

Hi,

When running "make flash" it should output something like this:

Flashing: _build/nrf52832_xxaa_s132.hex
nrfjprog --program _build/nrf52832_xxaa_s132.hex -f nrf52  --sectorerase

If it does not properly detect the .hex file, the output would be like this:

Flashing: _build/.hex
nrfjprog --program _build/.hex -f nrf52  --sectorerase

I suspect that you're seeing an output where "make flash" is unable to find the .hex file properly. You can fix this by manually running nrfjprog, or altering the makefile to provide (assuming that you're using nRF52832 in this scenario):

flash: nrf52832_xxaa_s132
	@echo Flashing: $(OUTPUT_BINARY_DIRECTORY)/*.hex
	nrfjprog --program $(OUTPUT_BINARY_DIRECTORY)/*.hex -f nrf52  --sectorerase
	nrfjprog --reset -f nrf52

Since you're using linux, it will use the wildcard "*" to find the only .hex file in your _build directory.

I'm able to flash the softdevice and program from terminal by typing the command as provided in the makefile, but am unable to do so using "make flash_softdevice" command. The output is

Flashing: s130_nrf51_2.0.0_softdevice.hex
nrfjprog --program ../../../../../nordic/nRF5_SDK_11.0.0_89a8197/components/softdevice/s130/hex/s130_nrf51_2.0.0_softdevice.hex -f nrf51 --chiperase
make: nrfjprog: Command not found
make: *** [flash_softdevice] Error 127

Ok, it was my mistake in adding the path. I added the path using "~" as my home directory, but when I use /home in the path, everything works fine. I guess I need to brush up my linux skills. Thanks for the help anyways.

What do you mean by adding the path? I think I run into the same problem.

[Lalit Kumar]

In bash.rc, while changing the path, you should use absolute path like

$PATH = $PATH:/home/<username/<your dir location>

What I was doing was this: $PATH = $PATH:~/<your dir location> The latter one gives the error I mentioned. Hope it is clear :)
