Thanks to everyone for the recent contributions (in particular eschwartz and jogawa, for discussing and clarifying the FW downgrade to 5.4.0) !
... And now, concerning the current CM status, specifically with regard to FW 5.4.2:
- I do have a "somewhat" working version (meaning: at least it doesn't crash immediately)
- that version handles part of the stuff correctly. And the other part is handled strangely, or it just plainly crashes.
So...: CM will most likely support FW 5.4.2. Probably sometime soon, but not right now. Just be patient
PS: @NiLuJe: merci pour les corrections!
