can't get D-shot working

[irekkin]

just installed a new F3FC board, new Aikon 30a esc's, running the latest version of Tri-flight. my tri flies better than ever. I do have a couple issues to work out though. the main one is I can't get D-shot to work properly. the copter will arm but the motors will not spin up. I've looked through the Tri-flight/Beta-flight wiki's and can't really find any relevant info. here is some CLI info that may be useful ,

here's the answer to the question I asked

Unfortunately the F3FC was designed before D-shot came around. D-shot requires hardware DMA ports, which the F3FC uses for other things. The 48pin F3 chip only has a few DMA enabled pins unfortunately. You may be able to, by heavily modifying the board to get it to work. But I have not tried it.
So you're stuck with Multishot and oneshot.
If it's speed you're after Multishot is slightly faster than D-shot600.
D-shot has other advantages though being a digital packet.
