@igalloway @hamishwillee @mrpollo Since PX4 1.15 is out now we like to introduce our own Pixhawk 6X-RT derivate (just different custom baseboard, but same 6X-RT FMUM)

[mrpollo]

Is it using the same PX4 target?

[igalloway]

Yes. It's fully in 1.15

[igalloway]

make nxp_fmurt1170-v1

Gerald can you confirm?

[mrpollo]

So, this is a new Pixhawk Autopilot Bus baseboard. Right? did you change anything on the FMU? if you didn't why not present this as a baseboard here? https://docs.px4.io/main/en/flight_controller/pixhawk_autopilot_bus.html

[igalloway]

Correct. It's very close to the Holybro one, but slight differences

• no coprocessor
• 3x CAN-FD (with signal improvement phys) -100Base-T1 Ethernet (2-wire)

[mrpollo]

It might be misleading to call it a flight controller. Why not call this a Pixhawk Autopilot Bus baseboard, and put this here? https://docs.px4.io/main/en/flight_controller/pixhawk_autopilot_bus.html

[dk7xe]

make nxp_fmurt1170-v1

Gerald can you confirm?

No, it's the same px4_fmu-v6xrt target in PX4 than Pixhawk 6X-RT. Baseboard is autodetected and T1 driver is used instead of 100base-TX.

In principle i'm with you Ramon. But NXP will sell the combination of 6X-RT FMUM + our baseboard as VMU-RT1176. The Pixhawk 6X-RT is purely holybro manufactured while it is unclear if they will commercialize the 6X-RT with our baseboard at all. I think from doc maintenance effort it would be better to just describe the basebord. But we would need then also the reference to our baseboard on the Pixhawk6X-RT page.

[igalloway]

It is only sold as a complete kit with FMUM and baseboard on NXP.com and through distributors worldwide. So it is a complete flight controller (reference design or EVK)

[mrpollo]

Please don't forget to include a link to the new page on the sidebar navigation file here, otherwise it won't be included.

[hamishwillee]

I'll look at this tomorrow too.

@dk7xe Best to get this as complete as possible so you don't have to come back to it, or at least not for ages.
