How do you know that the writing is ok, if the reading doesn't work?
It is normally possible to have the other situation, i.e. that you may read, but fail to write. But to say that the read step fail means that you must have managed to prove that you actually have managed to write valid data into the flash. But such validation requires some form of read... You only write "This function isn't ok". What function? And how do you know if you have a problem writing data to flash, or reading the data back from flash, or copying the read data to the serial port? What have you tested, and have you managed to eliminate any lines where you can prove that the lines are not responsible for your bug? How did you prove it? |
