13 years ago --- Quote Start --- actually i have my sgdma Tx and sgdma Rx mapped on a DDR , the same DDR where the CPU data an instruction is mapped. --- Quote End --- I'm almost positive that this can't work. Every example I've seen has SGDMA writing to onchip memory. --- Quote Start --- Now imagine i want to use an onchip ram for sgdma tx and sgdmarx instead of DDR. (but CPU still mapped to DDR) --- Quote End --- I would agree with this too. :-) --- Quote Start --- I tried direclty but this is not working. if you have any idea . --- Quote End --- Maybe it's not working for a non-SGDMA or memory reason. Compare to an example (e.g. the Altera NEEK development kit Ethernet code) and see if you're in the ballpark setting-wise. Bill A.
