DMA transfer using HAL

I don't understand what you mean by

"looking into the DMA rather than out of the DMA"

With Nios II 1.00 (the version I have) I have to use the ALT_DMA_RX_STREAM_ON and the ALT_DMA_TX_STREAM_ON macro's versus the new ones.

The issue I have is the confusion in regards to what they mean. You say its backwards, but the Nios II processor reference handbook for the previous version uses identical wording to describe ALT_DMA_TX_STREAM as the new version does when it describes ALT_DMA_TX_ONLY_ON

Old NIOS II Processor Reference Handbook

ALT_DMA_TX_STREAM_ON

"Sets a DMA tranmitter into streaming mode. In this case, data is written continously to a single location. The "arg" parameter specifies the address to write to."

New NIOS II Processor reference Jandbook

ALT_DMA_TX_ONLY_ON

"Sets a DMA transmitter into streaming mode. In this case, data is written continously to a single location. The "arg" parameter specifies the address to write to.

The only difference to me is just a typo with "tranmitter" in the old version of the manual.

Is the old manual just wrong based on your testing?

UPDATE - Nevermind I saw your explantion in another thread. The documentation is either wrong or just misleading.
