flash programming issue

[air]

Hello,

I'm preparing production.

My development environments are : 

 - SDK : V12.3.0, IDE : miniJLink, Softdevice : s130_nrf51_2.0.1_softdevice.hex

 - OS : Windows

I'm programming SD / application / boot seperately using nRFgo Studio now.

It's a little cumbersome.

So, I want to program them at once with the Lock and Protection on.

Would you let me know if it is possible?

 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.

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.

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

ERROR: The area to write is not erased.

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?
