UICR CUSTOMER erase

[Marco Pennacchietti]

hi,

my application use boot and soft device.

Is possible with the application erase only the customer register in UICR ? (of course switch off the soft device)

This because if I erase all user information I lost the address for the application and the boot does't not link the application any more?

Hi,

It is not possible to erase only parts of UICR, the entire UICR will be erased. If you have data in UICR that needs to be kept, you must read it out before erasing UICR and write it back afterwards. 

UICR is not intended for frequent updates. If that is the case, I would rather recommend you to store the user information in Flash, for instance using FDS.

Best regards,
Jørgen

I did so, now everything works fine.

I need this function only 1 time on the devices

Thanks
