I see that some significant changes have been made to packages in the latest bios packaged with EZSDK 5.04.00.11. In building my code I have linked in the EDMA package ti.sdo.edma3.drv.sample which still requires the bios.ipc package. Consequentially I have been forced to back to both the xdc and bios of the previous EZSDK to get my code to build, the newer Syslink and Ipc do not present any problems.
