We have had that some time ago but now do not have it anymore not changing anything. 

I wonder if it could be something like swapping the uart0 and uart1 lines maybe?

Hello Martin,
I succeeded to make the logomatic log thanks to your code, but when I try to use sd2log I get the following error : pprz.values_of_payload too many bytes…
I must admit that I haven't soldered the capacitor you mentioned. I might try that tonight but I doubt that it is the problem…
Did you make a change to the code that is not reflected to the github ?
I also noticed that the logomatic code is only in the dev branch (and this is not mentioned in the wiki).
Thank you for your help.
Cédric
