Hi, I'm using the nrfjprog (Ver. 5.2.0.45231) to program the board.
I wanted to insert
SoftDevice S110 +
Bootloader Hex file (provided from SDK 7.2 example) +
ble_hrs example hex file(with DFU).
So I wrote this at the CMD.
nrfjprog.exe --eraseall --programs s110_nrf51822_7.1.0_softdevice.hex --program ble_hrs.hex bootloader.hex --dfu --verify --reset
However, the program counter could not step into the hrs example.
At the bootloader, it told me that the apps inside bank 0 and 1 were invalid.
I cannot understand why this shows the apps as an invalid app.
If I program the board with ble_hrs.hex and s110 using nrfjprog.exe, the example works well.
What could be the problem?
