tfmini not working on V4 hardware

[ChristophTobler]

#8548 doesn't work for me on a Pixracer or Intel Aero...
I have tried on a Pixhawk (v3 target) and there it worked. On Pixracer and Intel Aero, I get

ERROR [tfmini] immediate read failed
ERROR [tfmini] Task exited with errno=11

Any Ideas @ayushgaud?

I was disabling mavlink on those ports https://github.com/PX4/Firmware/blob/master/ROMFS/px4fmu_common/init.d/rcS#L545-L554

Which serial port is it connected to? https://github.com/PX4/Firmware/blob/master/src/drivers/distance_sensor/tfmini/tfmini.cpp#L84

[ayushgaud]

I think it could be because of the hard coded serial port address. You may try modifying it according to your platform.

Sorry, forget to mention that I actually did that...
I used tfmini start /dev/ttyS3 on the Intel Aero (which should be the telemetry port) and tfmini start /dev/ttyS1 on the Pixracer (TELEM1, if I remember correctly)

[dagar]

@ChristophTobler did you stop mavlink on those interfaces (or prevent it from starting)?

[ChristophTobler]

@dagar I stopped the instances mentioned in the first comment. That should be enough right?
Can I stop a stream on a specific device (e.g. /dev/ttyS1) without stopping mavlink completely (mavlink stop)?

fix in #8726.
