We have a NAVx 2 MVP board that was working fine with our robot, and then we when updated to the current firmware (4.0.442) now it just gives a constant unending stream of CRC errors.
We plugged another NAVx board onto the bot with an older version of the firmware and it works fine still.
I was hoping that upgrading the roborio and code base to the 2022 release would fix it but we are still seeing this issue.
