MATEKF411 target doesn't work for F411-based Eachine Tyro79 quad, please fix or add separate target #4863

Closed georgie3 closed 5 years ago

georgie3 commented 5 years ago

Current Behavior

MATEKF411 target doesn't work on F411-based Eachine Tyro79. After flashing iNav the board boots and the LED blinks slowly then rapidly over and over, all communication fails. Betaflight MATEKF411 target works fine.

Desired Behavior

Please add support for the custom STM32F411-based Eachine Tyro79 FC.

Suggested Solution

Could just need a tweak to the MATEKF411 target, or could be a separate target. I'm a developer and could help, but I'd have to painfully compare the iNav and Betaflight F411 implementations and try things until it boots properly. I can help testing.

Who does this impact? Who is this for?

Tyro79 flyers who find Betaflight boring and love iNav :)

Suspect that they use the different gyro chip. Can you provide Betaflight's status command output?

georgie3 commented 5 years ago

Thanks for the quick response... yes it's definitely a different gyro/acc chip, ICM20602. Here's Betaflight 4.0.3 status output:

Try this firmware (it includes drivers for MPU6500/ICM20602 gyro and should work if it's connected the same way):

inav_2.2.0_MATEKF411.hex.zip

Awesome, this works. Gyro and acc behave normally in configurator sensor graphs and 3D OpenGL view. I can't flight test yet because I'm still waiting for a receiver that fits in my Tyro79, but all looks good... motors run in test mode.

Good, closing this then
