You need to do an erase all (-e) before writing to UICR (-rbo ALL), it think that's the problem.

Du you have a log?

The error message is display in --verify --program procedure.

ERROR: The area to write is not erased.

I found it.

1. I merged all.

- mergehex -m s130_nrf51_2.0.1_softdevice.hex outer_v1.5.20_20180730_1410.hex boot_set_v1.5.20_20180730_1410.hex -o all.hex

2. program/verify and read-back protection

nrfjprog -f nrf51 -e
nrfjprog -f nrf51 --verify --program all.hex
nrfjprog -f nrf51 --rbp ALL
nrfjprog -f nrf51 -r

3. It fails sometimes.

I don't know why.

Would you let me know more why?

Thanks.

See Merging files with mergehex, and nrfjprog DLL or nRF5x pynrfjprog. You'll need to write a script that writes 0x00 to RBPCONF.PALL register in UICR at address 0x10001004 after it has flashed the merged hexes.
