    Hi,

    I am using a ST72521 MCU in my project.

    I have a problem with IAP.

    When i try to erase sectors it is successful.

    Byte write is also succesful.

    But Block Write is failing.

    What are the different reasons for this problem.

    Thanks,

    Sarav

    you have to ensure that the parameters are passed correctly i.e. the source buffer address (located in the RAM) and the number of bytes etc. You can read the error status(returned at 0xFF) and find the exact error. The information about the error status is given in the ST7 flash programming manual. You can also try with a higher FREQ value.

    regards,

    venky
