XAPP1078

Former Member

I downloaded the ZedBoard version of the XAPP1078 reference design and copied the generated files to a SD Card. CPU0 runs Linux fine, but CPU1's bare-metal application does not. I have to connect XMD and send  'con 0x18000000' to get CPU1 to run. The FSBL copies the .elf file into memory okay, but something goes wrong after that. There is a Xilinx wiki page for XAPP1078 that indicates the Xilinx ZC706 board has version 2.0 silicon with a different ROM bootloader requiring changes for the reference design to work. Could this be my problem as well? How do I know which chip version is running on the ZedBoard?

    The Rev D ZedBoard has the newer, production silicon. A Rev C. ZedBoard has the earlier ES silicon.

     

    You could also read the MCTRL register (see UG585, the Zynq Technical Reference Manual for bit definitions) by launching an XMD console in the SDK with the JTAG cable connected and connect to the ARM by entering "connect arm hw" at the XMD% prompt.

     

    Then enter mrd 0xf8007080 at the next XMD% prompt to read the MCTRL register at 0xF8007080.
