    2727Some bugs and workarounds we've figured out for Xilinx SDK 13.4 on the WARP FPGA Board v2.2 (Virex-4 FX100 FPGA).

    30 '''XMD: Unable to decode ELF start address'''

    3231When using the SDK "Run" launch process targeting a PPC design on the Virtex-4, we get an XMD error "Unable to decode ELF start address (), assuming 0x0."

    49 '''PPC ISOCM access via XMD'''
     47=== PPC ISOCM access via XMD ===

    5149The PowerPC instruction side on chip memory (ISOCM) interface is a useful feature- a memory block for code which the PPC can access without occupying the main PLB. But, because the ISOCM memory is not on the main PLB, the debugger cannot access it directly. The PPC405 core provides special instructions and registers for accessing the ISOCM interface via the PLB. The debugger (XMD) can use this passthrough, but it requires specific flags be passed during XMD initialization. Unfrotunately Xiilnx did not automate the process of setting these flags, even in projects which use the ISOCM.
