Hello Everyone,
I am using nrf51822 with S130. After completely erasing the chip, with the below mentioned code snippet in application code:
NRF_NVMC->CONFIG = NVMC_CONFIG_WEN_Wen << NVMC_CONFIG_WEN_Pos;
while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
*(uint32_t *)0x10001080 = hexData;
NRF_NVMC->CONFIG = NVMC_CONFIG_WEN_Ren << NVMC_CONFIG_WEN_Pos;
while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
I am able to write data in the UICR register. I tried subsequent writing to UICR using the same code in the application code, however, UICR data doesn't change. Based on further research I came to know that the entire chip needs to be erased for writing new data. However, I want to just erase UICR to rewrite new data to the UICR. Is there any way to erase the UICR registers in application code to rewrite new data?
Thanks
