Thanks Xavier

TFT:

I’ll dig up the midi project and strip it down to what fails - I’ll test with 0.98b first so I dont waste your time though !

I’ll try to find time tonight to see if I can build a debug version (I’ve used openocd/gdb for debugging stm32 before so will give eclipse a go !! It’s many years since I’ve used it !)

No TFT problems for me with DC power.

I’ve been having quite a few total lock-ups though (specifically with one or two midi sequences, loaded into ableton and playing over din midi). Not seen any issues other than on those two files.
I have just setup stm32cube and plan on looking into it over the next weekend (I’ve got a few stlinks lying around so will probably set one up on my preenfm3 and see what I can find. If I can characterise the bugs better I’ll submut an issue on GitHub....

(I’m presuming all I need is stm32cube ide to build the fw - I normally use the arm toolchain directly from the command line but looking at the dot files on github, I am assuming it is stm32cube h7)

By the way - how many PreenFM3s are there in the wild now ?

I love the ui on the fm3 by the way !

(I also built an FM2 at the same time as I heeded the warnings about fm3 fw stability ! I’m very confident it will be amazing very soon !)

I’ve just noticed the preenfm3 controlboard has been revised. I was about to buy parts to build the fm3 having just received boards. Are there any hacks or different parts needed on the old boards? (I’m happy desoldering/using kynar wire on smt so if there is any benefit in hacking the old board I’m happy doing it - I havent compared the old and new schematics yet...)
