Problem with external I2C on Omnibus F4 boards

[samp38]

Hi,
First, thanks for your work. It's amazing how Triflight drives my Trifecta. However, i can't remap I2C (whose pins are shared with UART3 on the Omnibus F4) to B10 - B11 pins. It seems that i2C is not active on the Omnibus F4 target. Is there a way around? I need to connect an i2C magnetometer to my flight controller.

Thanks

I tried to add i2c definition in target.h but there is no way to get I2C2 working on pins PB10 and PB11. As soon as i add "#define USE_I2C" in target.h the vcp doesn't appears on startup. Does anyone had the same kind of issue? Thanks.

I'm working on rebase on BF 3.2.2. Hopefully the I2C will work there.

Great news! Thanks for your work and let me know when this is done! Sam
