General Description: When generating an XMD Options file from the Tools menu, the "isocmDcrStartAdr" attribute is not set.
This must be taken from the "C_IDCR_BASEADDR" parameter on the "ppc405_virtex4" Core. In Virtex-4 devices, all the internal DCR regs are offset from 1 single base address. In the case of ISOCM, the offset is 0 from the C_IDCR_BASEADDR.
The correct value can be specified by opening the "xmd_ppc405_0.opt" file found in the "<project_directory>\etc" directory.
