Hi @flywoo . Have you read the new hardware policy? https://github.com/iNavFlight/inav/blob/master/docs/policies/NEW_HARDWARE_POLICY.md

Please contact me on [email protected] on how to proceed further

@DzikuVx ok, i sent email .thank.

Hi @flywoo, please could you add the FLYWOOF411HEX target as well?

@harry1453 OK。

Hi DzikuVx,
It looks like there is a problem with I2C because the magnetometer does not work.

@edyno apparently target not assigned external sensors correctly to I2C bus.
I have prepared a fix but would like external tests. So please flash file from the attachment and test, please
inav_3.0.0_FLYWOOF745NANO.hex.zip

Bingo, I2C works :) Thank you.
FYI: CPU load has increased approx. 3 times, compared to firmware 3.0.0 from the official "Flywoo download page". Before that it was about 4% now it is about 12%.

I have no idea what was on the flywoo side but I expect it was something ancient. The load you are getting right now is what is expected from 3.0

OK I'll test more. I hope you are right. Thank you for your prompt support.

@DzikuVx I am also having issues with I2C. I have flashed the latest RC2 hex (I have not tried the one you posted in this ticket). Did your fix get pushed somewhere? I'm only seeing 1 commit in the PR and didn't find anything in a quick search.

@nknotts RC2 was released 13 days ago and the fixed build was posted here 11 days ago so it's definitely not fixed

Sorry, I missed that. I just installed the hex linked in this PR and I2C works as expected. Thanks!

No news for INAV/FLYWOOF411HEX 3.0.1 ?

@flywoo could you please provide the target for the F745HEX FC?

it seems like the default F745 Target can not be used, there are at least some conflicts in the used ADC pins between inav Firmware and Betaflight firmware.

also the firmware published on https://flywoo.tawk.help/article/firmware-inav (FlywooF745HD) do work for flying, but no current readout is possible.
