I only want to erase one page(no.254 or no.255) using NVMC !

Now, I can write the data to flash(but only once),and I can read data from the flash. Those all be OK. But I want to write data more than one times. So,I use the NVMC to erase the flash page, but always false. Now, I only need several sentense code to erasing one pages for example no. 254.

I use nordic 's lib ,but always error. so, I want to write some code to op the flash follow the guide nRF51_Series_Reference_manual v3.0.pdf .

I try some code, but alway faile when I erasing the flash. Now , I think that maybe some detail was lost in the documents, the nordic provide.

Are you using a SoftDevice? How are you erasing flash? What function? What arguments? What does the function return?
