SCR_ENABLE breaks MAVFTP

ArduCopter Copter 4.3
1

Setting SCR_ENABLE = 1 and rebooting causes MAVFTP failure (see below)

Flipping it back to 0 fixes the problem.

SD card is healthy and has APM/SCRIPTS folder

Please help!

Probably running into memory limits on your flight controller

3

you are not going to be able to run scripting on that flight controller it just doesn’t have enough power with all the other features turned on. F7 at the least is needed for any scripting.

4

are you saying scripting can’t work with fmuv3? there is nothing besides GPS, buzzer and ESC attached to this board so should have plenty of free memory.

5

very simple scripts work but not without limitations like no mavftp.

Get another flight controller. I screwed around trying to get a couple scripts running on a PixRacer and they didn’t work.

Thanks, what controller you recommend as an upgrade from fmuv3?

I managed to get MAVFTP running by decreasing SCR_HEAP_SIZE, now let’s see if I can get any scripts working…

Any H7 based supported board.
