    Hi,

    I am trying to read the flash content of the Main-Flash during boot-up (IAP - boot code is located in Boot-Flash).

    Purpose of my question: I need to create some sort of check sum for the content of the Main-Flash.

    I managed to switch from Boot-Flash to Main-Flash and vice versa, erease of the Main-Flash is also working. If I write a byte to the Main-Flash using the Polling-Mechanism for verifying it seems that the writing was ok.

    But if I try to read a byte manualy I only read ''trash''.

    Any hint is welcome.

    Best regards

    Sebastian
