> I remember seeing values between 15 and 21 but I don't have it set up anymore. hmm both those values fall in the [1 bucket.](https://github.com/PX4/PX4-Autopilot/blob/main/platforms/nuttx/src/px4/stm/stm32_common/board_hw_info/board_hw_rev_ver.c#L94)

Can you print it here https://github.com/PX4/PX4-Autopilot/blob/32aa3263a60d48a960eb8a2ccc50073815250889/platforms/nuttx/src/px4/stm/stm32_common/board_hw_info/board_hw_rev_ver.c#L87

Ok I can see that dn scaling is seeing 15 as a 0 @CUAVcaijie What tolerance R's did you use?

@PetervdPerk-NXP - Rebased on man and added the rest of the paths.

@PetervdPerk-NXP Shal we un-draft this?

~~@wating on https://github.com/PX4/PX4-Autopilot/pull/23021~~ - Done

@PetervdPerk-NXP - I have brought in the usdhc changes. I think it is ready to merge. Can you verify the overall functionality and that I did not miss anything.

@dk7xe Please Fly this and compare to main

@dagar is there a way to get this through full CI and the test HW platform?

@dk7xe I should have backported all rt6 commits. Of course all the commits from @PetervdPerk-NXP to PX4 since 10/2023 will not be backported. That is what the next release will...
