West flash command not work.

[Dinkar]

Hello,

We have a custom board for nRF52805. We have one LED connected to the GPIO. I wrote the FW for Blink LED every second.

I build the FW using the command "west build -b my_board -p always". it generates the zephyr.hex file. I flashed that file with various methods as follows.

1.  Using west flash
   1. command: "west flash --reset"
   2. result: LED did not blink.
2. Using west flash with erase
   1. command:
      1. "nrfjprog --eraseall"
      2. "west flash --reset"
   2. result: LED did not blink.
3. Using nrfjprog command
   1. command
      1. "nrfjprog --eraseall"
      2. "nrfjprog -f nrf52 --program build\zephyr\zephyr.hex --verify --reset"
   2. result: LED blinks every second.
4. Using nRF connect for desktop application
   1. use zephyr.hex and select "Erase&Write" options.
   2. result: LED blinks every second.

Can anyone explain why West Command is not working? how to solve this issue?

Thanks,

Hi Dinkar,

Are you flashing the same exact firmware every time? If so it is odd that you see a different pattern in the LED blinking. Can you share full console log showing the commands you use to program and all the output?
