<![CDATA[UAVCAN error in FC v2 px4 firmware]]>@Eric-Katzfey @Alex-Kushleyev

I have the ark flow MR attached to the FC. While I want to check the standard builds, the standard build do not have UAVCAN modules enabled. i have to enable them manually.

If anyone could share the built px4 file for the ModalAi FC v2 along with UAVCAN enabled and collision prevention working, It would mean alot.

I am able to build, my build is not able to have both collision prevention and uavcan working. if i go to the latest version the hearding error is showing up, prearm check is not passing.

I checked with px4 mainline as well as modalai fork,

branches including - voxl-fpv-dev, version 1.17-dev
main branches - release/1.17, 1.16, 1.15

None of the above have the UAVCAN enabled, I do it manually, and the UAVCAN error is solved.

If you could guide me to a version of PX4 where both of this works with Flight core v2, or share the px4 build, if you have it working, i could test it out .

Something from the ModalAI fork of PX4 or from mainline? Are you not able to build firmware yourself?
