witch answer is ok ?

NRF_NVMC->CONFIG=1;//FOR write --------------------------it would be due here for(int tmpi=0;tmpi<32;tmpi++) { NRF_UICR->CUSTOMER[tmpi]=dataflash[tmpi]; } NRF_NVMC->ERASEUICR=0; NRF_NVMC->CONFIG=0;//FOR READ

What is wrong with the code in the link? Please discribe your issue in more detail. Do you want to write to flash or UICR registers?
