Ev3dev: run-direct in Kernel Release Cycle 10

[laurensvalk]

If I understand correctly from the release notes, the following should still work on 3.16.7-ckt26-10-ev3dev-ev3:

If you need unregulated control of motors (speed_regulation = off) use the run-direct command

echo run-direct > command
echo 30 > duty_cycle_sp

This does not work (the motors do not start moving). Are any additional steps required to start the motor?

No, this should work, but it is not working for me either with the official packaged kernel.

Haven't tested it, but pretty sure I found/fixed the bug already. I guess kernel cycle 11 will be coming sooner than expected since this is a critical bug.

Thks @dlech - it's about time I got the kernel updated on my EV3 development brick so I can fininsh the Python binding anyways :-)

Fix has been released in kernel v4.4.9-11-ev3dev-ev3.
