I want to thank you for continuing to post your mSGDMA progress here even though you're getting very little if any help or feedback. I'm in the process of folding the mSGDMAs into our A10 SoC dev kit design to DMA between HPS memory and FPGA memory. I'll share any problems and/or solutions we find.

As we're running on custom hardware, I've also contacted my FAE and Altera directly through support. It's very frustrating as nothing seems to be performing in a deterministic/expected manner.
On a related note, it is fascinating, but I can't figure out how to get an mSGDMA out of park mode. I'm obviously doing something in the wrong order, but nothing in the documentation is providing strict guidance.
It also is odd that the first capture that I do fails, but the second always works. I'm thinking there is something distinctly wrong here. It might make sense to switch to the Altera scatter-gather from the mSGDMA if this continues. Considering the mSGDMA is used in all the Altera components (TSE), something else is probably going on.
