Hello,
I encountered this issue 
" -1:MC_ROLL_TC is missing "
Can someone tell me what’s going on ?
Thank you
Hello,
This issue seems to be linked to Pixhawk firmware update.
The initial firmware was 1.7.0 and when I updated it to 1.8.0 I incountered this issue.
After reloading the 1.7.0 firmware as custom firmware, this issue was not found.
