    I'm trying to write a BSP for the Starterkit. When I connect to the Starterkit with a JTAG debugger and let the bootloader initialize the board then I don't get any access to the internal registers at 0x80000000. The debugger and even my software always read 0, even if the registers are RW. I can successfull read and write the RAM 0xC0000000 and the board registers at 0x70000000.
    Is there any trick? MMU is on and mapped but Cache is off.

    Thanks.

    towie,

    This might seem a bit simplistic but I would check to make sure your JTAG jumpers are set correctly on your App Board.

    Yes, it was really a matter of correct JTAG setting. Now it works fine.

    Thanks.
