Hello:
Why do I erase SDK5.2 version of flash and read not, in SDK4.2 can. I tested nrf51_sdk_v5_2_0_39364\nrf51822\Board\nrf6310\flashwrite_example is a good example.However...
before i write the flash, it has been erased.so ,its value is all 0xff.
when i write 0x00 to flash address 0x0001,the value read out is not 0x00 but 0x01,and the value in...
