Arducopter 3.6.6 - Pixhawk 1: Motor Test does work under NuttX, but not under ChibiOS


I installed Arducopter 3.6.6 under NuttX and Motortest with Missioplanner does work. After installing 3.6.6 under Chibios Motortest does not work anymore. Motors beep twice and that is all.

Have you tried calibrating the ESCs before testing the motors? I ran in to that issue a few days ago.

After trying many things I got it to work. I need to first plug in the battery and afterwards the usb cable. Then starting the motor test and it works

Glad to hear you got it sorted.
