Hi all, I've tested (temporary) write-protection feature of eMMC flash.
#1. set the temporary write-protection (using CMD28) #2. write data to the write-protected area (using dd or similar) -> gives no error at all. #3. checking the area confirms that write-protection is working, data is not over-written. In step #2, I expected some error return, but no. Obviously write-protection is working, but user can't see any visible output. Shouldn't write(2) return some error for above case? Jongman.
