Hello,

Here's a new topic to discuss Navio2 specifics in regards to the new sd-card image and apm binary that were released this morning.

The official docs are here:

This is awesome thanks a lot for your work Emlid!

Looks like everything is working well. I obviously haven't flown yet. I just launched ArduCopter sending telemetry over wifi to Mission Planner, and it looks like I am getting all sensor data properly.

We also now have a newer kernel:

pi@navio:~ $ uname -a
Linux navio 4.1.6-v7+ #2 SMP PREEMPT Thu Jan 28 19:58:25 MSK 2016 armv7l GNU/Linux

Here's what cpu usage looks like on the rpi2:


PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
886 root -13 0 46376 44908 3500 S 49.0 4.8 4:50.78 ArduCopter-hexa

I am not seeing the 15-20% cpu usage cause by the irq storm of the old dwc_otg usb driver. I wonder how you managed that!

I'll pursue my tests and put my updates here.
