Hello, is it possible to chain QDMA and EDMA? I want EDMA to reload SRC and DST of QDMA. What I want to do is transfer 134 blocks of 8 words to different locations in memory. There is no patern in this blocks so can not use a 2D EDMA. So I configured QDMA to transfere 8 words and chained it to a EDMA. EDMA reloads SRC and DST and should trigger a new QDMA cycle. The 1st QDMA is triggered manualy and is performed. The 2nd one should be triggerd by EDMA, but isn't. EDMA is run one time and write a value to QSRC and QSDST. A write to QSDST should trigger a QDMA cycle. Manually it works but not by EDMA. Any help would be appriciated. regards Gustl |
