Can you provide some of the C code you used to control the dispatcher. I am trying to save streaming data to SDRAM on the De0-Nano board, but even though I can write in the descriptors, the dispatcher doesn't execute them. So I'm wondering what is wrong.. I followed the same code procedure seen in the Modular SGDMA demo on alterawiki. Are you using the standard or extended dispatcher, i've tried both but neither worked for me. not sure where the error is. Thanks. My qsys set up is as follows: Transfer mode: streaming to memory Descriptor fifo: 32 Data width: 32 Length width: 20 FIFO depth: 64 Burst Enable: on Maximum Burst Count: 16 Force Burst Alignment: on Full Word Access Only
