All in One inverted mounting roll error

I have mounted my all in One board up side down to the bottom of a lid in the cab. I have the roll offset to 180deg. The roll will read in the -5 to 5 deg range then randomly switch to -355 to 5 deg, this causes some very unpredictable steering. When the board is right way up and roll offset of 0 it works fine.
Ver 5.7.2, single antenna, bno085.
Has anyone come across this before?

I ran our combine that way for awhile. It steered ok even when showing 355deg off. It seemed only a display error.

The bno doesn’t show real heading, when it powers up it starts at 0. AoG just uses it for heading change.

I’m experiencing the same issue with release 6.3.3. @sarge @Davidwedel do you happen to know if this issue is still present in recent versions (6.7.x) of agopengps?

I checked most of the change logs but couldn’t find any related PRs. But maybe I missed something

No idea, but I doubt it’s been fixed. I just bought some standoffs that were a little taller than the PCB and components, and mounted the PCB the right way.
