UART DMA for 2024

ArduCopter Copter 4.4
1

Matek H743-WLITE with TBS Crossfire on UART6/Serial7 per the Matek instructions. AC4.4.4

This build hasn’t flown yet, but so far it looks like everything is working as expected. No issues there. However I’m getting that old error “CRSF on Non-DMA Serial Port”. Feels like a blast from the past…

As far as I understood this wasn’t an issue on H7 boards. Is this a warning I need to be concerned about? I’ll probably upgrade to 4.5 very shortly to take advantage of the new CRSF parser updates, will that clear up the issue?

Not sure you’ll avoid the warning, but @andyp1per assured me it’s a non-issue on the H7 boards.

I ran that way for quite a long time on 4.3 and 4.4 without issue using ELRS.

If Andy says it’s a non-issue then I’ll happily move on. Thanks!
