nRF51822 cannot write data to flash

[sunnyjet16]

Hello,

I am writing some data to flash, but when it runs to storage_clear, I get the return code---0x10. It seems clear failed. And I tried storage_update, and it failed with 0x10 too. Anybody can help out for this?

Thanks Alex main.c TestAsc.c

0x10 is NRF_ERROR_INVALID_ADDR. pstorage_clear() will return this if you use an address that is not word aligned.

Hi Petter,

I read the address of the block to be cleared. Its address is 0x2000201C which seems aligned with word. And I checked the data of block. And inside the block, block_id is 0x00027000. And to test if the address is available or not, I used pstorage_store and the return value is 0. I guess probably there are other issues which cause clear fail and update fail.
