After downloading a DF log, when I tried to open it in MP, I got the error message saying “Missing FMT message”. The FC is Open Pilot Revo with no SD card. I have other Revo in my fleet and they work without problem.
I posted this question in Dec 2023 and was asked to use plot.ardupilot.org to check, but still not work. Attached is the setting of the LOG param.
Seems no one can give an answer to this problem in the forum.
Anyone who has clue, pls help.
Update to ArduPlane 4.5.7 and retest. It might be a real bug that might meanwhile got fixed.
And you can post a log file for check.
Hi Andras,
Here is the log file for check. Thank you.

Just updated to Arduplane 4.5.7, and tried opening the DF log, still with missing FMT file error message.
Anyway, thank you.
Did you make a new log with the 4.5.7 or did you just try to download old logs ?
I don’t see any revo/dataflash specific fixes since 4.0.4, but perhaps it is still a bug that is fixed (but since your other revo’s are fine, it is more likely that the dataflash chip is faulty on your board).
The file is gibberish, with large parts missing from the beginning.
I just tried to download the old log. I know it may not make sense. When weather permits, will try to fly and make a new log.
Thanks.
Just remove the props, arm and imitate flying on the desk. It will generate log for checking.
I imitated flying on desk as you mentioned, can download but could not open the file, and the file shows 0 byte.
Don’t know what has gone wrong. Will try other ways to solve the problem later.
Thanks
