I’m trying to make a bare minimum board config with EKF2 that fits in Kakute F7 flash (1MB). I’m OK using RC control only (no need for mission following). I’m at 107% flash usage with the following: DRIVERS adc barometer/bmp280 #dshot gps imu/invensense/icm20689 #imu/invensense/mpu6000 magn…

You can see what is enabled for FMU-v2 which is also a 1MB flash: PX4/Firmware/blob/master/boards/px4/fmu-v2/default.cmake px4_add_board( PLATFORM nuttx VENDOR px4 MODEL fmu-v2 LABEL default TOOLCHAIN arm-none-eabi ARCHITECTURE cortex-m4 ROMFSROOT px4fmu_common BOOTLOADER ${PX4_SO…

Hİ @j_p i also try to use ekf2 on Kakute F7 v1.5 I will use px4flow and a companion computer. I think your problem fits mine. Could you please share cmake doc to help?

@altug This is what I was flying last. I tried 1.11 beta, but had some issues with 2 motors not running. px4_add_board( PLATFORM nuttx VENDOR holybro MODEL kakutef7 LABEL default TOOLCHAIN arm-none-eabi ARCHITECTURE cortex-m7 ROMFSROOT px4fmu_common CONSTRAINED_FLASH SERIAL_PORTS TEL1:/…

Thank you @j_p As i saw u disabled dshot. May I ask did you use dshot esc or one shot traditional? I use Kopis2 6s setup and have an issue that i think about escs.

This is my secondary “crash-cheaply” drone that I use to test Px4 integration with the companion PC and data-link. It’s running cheap Turnigy Multistar 32bit PWM ESCs that are more than enough for my needs. Although I must admit I consider moving to something more digital…

@j_p Did you get this working? I tried 1.11 beta and had similar motor issues. Im reverting to 1.10.2 but so far have not been able to get it to spin all 4 motors.

No, I did not, and reverted back to 1.10.2. I might be able to spend some more time this weekend and make a new build from Git to see if anything changed.

Hi, I’ve got ekf2 compiled on the KakuteF7 by deleting some modules, but the problem I have now is that there are errors in the AHRS and Pre-arm check (I’m seeing this from QGroundControl). Has anyone got the EKF2 actually working and flying with it? I’m not using GPS or magnetometer. Just the IM…

Hey, I’m still working on this actually with no success so far. Baro and Mag aren’t working AT ALL on a KakuteF7 (for me) right now so maybe that’s creating issues with the EKF2? Because compiling a “bare minimum” isn’t that hard it’s just that this still won’t lead to any improvements… ;D Please…

Been trying some more and so far I can see the Baro working in Mavlink Inspector - Altitude just not relaying that info to QGC… But all my compiles towards the EKF2 do not get it working correctly yet. It looks all fine except for when doing Calibration - Level Horizon it errors “estimator not run…

CONSTRAINED_FLASH did the trick! Also thanks for the link to the config file for inspiration.
