    Hi - first post here. I bought 3 of these stacks. They shipped with betaflight 4.0.4 I believe. No issues with barometer. As soon as I updated to 4.1 the BARO,ever was throwing off i2c errors. Any help or guidance appreciated, thanks!

    What if you roll back the FW does it work again?

    Hi - so...I have three of the same stack, one uninstalled so it’s easy to muck around with. I discovered that the barometer does work whether 4.0.4 or 4.1.0, however 4.1.0 that says holybro or similar in the flash does throw off an i2c error (though works’. 4.0.4 does not throw off that error, and neither does 4.1.0 under the legacy for the Kakute 7 (despite having the same file name and time stamp, or so it seems). I captured a diff batch from both 4.1.0 versions if it’s worth posting, and I can flash again the 4.0.4 if worth doing as well. Thank you for any suggestions or help.
