I'm currently having a problem making the CRP work and I'm production...
I though it was working correctly, but it seems not.

I'm not sure how I must activate CRP. I'm using :

- J-Link
- LPC4357 Flash Bank A : Secondary bootloader + User application
- LPC4357 Flash Bank B : Utility User application

What I tried so far :
- Generate my bootloader.bin that will be written at address 0x1A000000. After generation, using JFlash, I manually modify address 0x1A0002FC to enable CRP1 (0x12345678)
- Power cycle
- Try to read back the chip memory using JFlash : working (and should not)

What am I doing wrong ? What's the best way to enable CRP using my setup ?
Thanks !!!
