nrfjprog program every second time didn't start the application

[Dominik Eugster]

Hi

When I use the nrfjprog with the command line:

nrfjprog --recover

nrfjprog --eraseall

nrfjprog --program testcode.hex

nrfjprog --rbp ALL

The application is starting and the code running.

If I do the same again (with the same hex or a newer one) the nrf remains in the bootloader.

The only solution is to do it again, every second time this bug is happening, why? What is the solution for this?

Regards, Dominik

this code works now:

@ECHO off

REM nrfjprog --log

set "HEX_FILE=testfile.hex"

echo **********************************************************************
echo "Recover and disable the read back protection"
echo ********************************************************************** 
nrfjprog --recover 

echo ********************************************************************** 
echo "%HEX_FILE%"
echo ********************************************************************** 

echo **********************************************************************
echo "Program and reset the Device
echo ********************************************************************** 
nrfjprog --reset --program %HEX_FILE%

echo **********************************************************************
echo "Verify the device
echo ********************************************************************** 
nrfjprog --verify --fast %HEX_FILE%

echo **********************************************************************
echo "enable the readback protection"
echo ********************************************************************** 
nrfjprog --rbp ALL
