Kakute H743-Wing with INAV 7.0.0: ledstrip does not work

[Torchi]

I have got a Holybro Kakute H743-Wing FCB and the problem I report is that I have never seen ON any led of the strip. Everything else I am testing of the FCB (servos, peripherals, functions, etc.) is working fine.

I connected a ledstrip (PandaRC LED0539 RGB 5V). I loaded at first INAV version 6.1.1 and it did not work. Afterwards, I have understood that the ledstrip function is not complete in 6.1.1 sources.
Then, I loaded INAV 7.0.0. This version seems to support well the Kakute H743-Wing... except for the ledstrip, it seems to me, as still I do not see it working (I have never seen any led turned on). I have checked, with another model and INAV version, that the ledstrip itself is perfectly ok. I think the configuration I use is ok (in any case, I attach the dump). The ledstrip pins are connected to: GND, supply and the M14 pin. As supply I tried either +5V or Vx (that is 6V and is dedicated to all servos): neither worked.

can you please test the Artifact build from here: https://github.com/iNavFlight/inav/actions/runs/7546952104/artifacts/1173380099

this has some fixes for the target definitions that did not match the manufacturer definitions.

There are still problems to understand. What I did is described in the following.
I loaded the fw version you sent, variant for H7 WING, i.e. inav_8.0.0_KAKUTEH7WING_ci-20240116-c19439b.
I have no v.8 configurator so, from CLI, I have just input commands e.g.:

feature LED_STRIP led 0 0,0::C:10

and I connected a 4-led strip to GND, M14 and 5V.

I attach the diff file. release 8 diff.txt

What happens is that sometimes LEDs light up, sometimes not, Depends on the startup. A boot sequence that sometimes works (rarely) is: first connect the controller to the PC, then connect the battery (thus supplying servos and LEDs).

OK thanks for trying but sounds there is at least some difference. Will do some testing later too. the website for automated snapshot builds is down at the moment to get a 8.0 build and I have no build environment set up. need to work on that :D

As conclusion of a day in which I tested the fw version inav_8.0.0_KAKUTEH7WING....mentioned above. In the day I have seen the LEDs lighting up 3 or 4 times. I did, in total, about three hours of testing ie. several tens of cycles of various configuring, switching on/off, etc. So , LEDs CAN light up but, for some reason (a gut feeling: hw initialisation timing?) , the successful cases are rare and I could not see any pattern. I am even thinking that, trying so many times, the previous version 7 could behave same.

OK I leave it open with the BUG lavel and a dev with the board need to look at it.
