nrf_fstorage_erase returns invalid address error

Hi, 0x007F004 is not aligned to a page boundary. 0x007F000 is. Erase operations should be aligned to a page boundary. Try starting the erase at 0x007F000.

I've figured out the problem and it was an error on my behalf because i didn't fully understand how the fstorage system worked. Because I only want to use one page in flash I should only be erasing that one page and not fiddle around with the other pages unless I am planning on writing to those pages. The problem was that I was providing an address to the erase function which was an address inside the page I was using. This meant that it wasn't the address of the next page hence it was not at the page boundary. I fixed the problem by always providing the address of the first page to the nrf_fstorage_erase() function.

Yeah, it seems that way. Although I'm not entirely sure where this un-alignment is happening, because I think the addresses and pages I'm providing to the function have all been aligned.

The information you asked for, right before the system returns the error is:

p_fs->p_flash_info = 0x00031920 (&m_flash_info), page_addr = 0x007F004

It seems you are trying to do an erase operation beginning from an address that is not aligned to a page boundary.

Could you check what are the values of p_fs->p_flash_info and page_addr?
