So, TX DMA works (from SDRAM to USB FIFO), but I must have messed up somewhere because it repeats stuff a looooot of times. (I'm testing with USB serial and this is very obvious when sending text haha)

Good news again! USB DMA TX works, at least for small transfers!
<iscle>
Florianclume: Why are you specifically looking for boot1?
<iscle>
DMA works in both directions, but for some reason some transfers get truncated (or the usb serial gadget is not working, which I doubt). Basically, when sending 1, 2, 3, 4, or 5 bytes, it works just fine. Then, 6 and 7 get truncated. Then, 8 bytes start working again.
