There's probably a better place to continue discussing this, but just thinking that for word read/write (without block locking), we can do something like this: * read will do the read, check the flash ECC error register, and use a return code to indicate the error * write will first do a read, and only attempt a write if the read returns 0xFFFF _and_ an ECC error Read can return one of `OK`, `ERR_UNWRITTEN`, or `ERR_BAD_ECC` Write can return one of `OK`, `ERR_ALREADY_WRITTEN` That should hopefully prevent data corruption in most use cases? -- This is an automated message from the Apache Git Service.
