SN data in flash is lost

[visionwang]

I put SN on page0 of nRF52832's flash, page0 is protected(page 0 only has sn data);

But  SN  will be lost sometimes;

PLS help, thanks!

SN is written to flash by application code;  When SN is correct, data in page is correct,too;  some of nrf52832 cann't be read  because JLink don't know nrf52832, why?

Could you try to update your Jlink driver? v.5.12f is quite old, they are currently on version 6.46k: https://www.segger.com/downloads/jlink/#J-LinkSoftwareAndDocumentationPack
