I replied in that other Logging Failed thread. I see you’re on 4.0.4 already, try doing the bootloader update.

Hello,
I use for my drone the autopilot MAMBA H743v2, all components work well.
The problem is that I can’t get DATA FLASH LOG to download. And if I manage to get a log and download it, I can’t visualize it and it shows me an error message saying when I can’t open it because the FMT message is missing. and sometimes the message “logging failed”.
Someone has had this kind of problem! or knows how I could solve it please!
