    Hi fatima,

    I forgot to mention that you stated you are using AMBA 3 AHB-lite, but throughout your code you have references to HBUSREQ and HGRANT for multi-master arbitration, and also RETRY responses from the slave, also used for multi-master systems.

    AHB-lite does not have any of these signals as the bus only supports one master, so does that simplify your design, or are you designing to use AMBA 2 AHB ?
