Im trying to transport DATA to my ethernet TMAC using the Build in SDMA. The Problem is that I have also an XPS Central DMA controller in the system performing other tasks ... both are running on the same PLB bus and thats seems to cause problems. Is there an way to add an second PLB bus to the Microblaze core? Or an way to use the Hard ethernet Mac with XPS central DMA instead of the build in SDMA???
