RPi2 autopilot baseline Linux configuration

[mhkabir]

Opening this to track our work on getting the POSIX port running on RPi2/Rpi0 hardware combined with the currently available interface shields from ErleRobotics and Emlid.

RPi header pinout :

Buses :

• SPI : /dev/spidev0.1, /dev/spidev0.0
• I2C : /dev/i2c-1
• UART : /dev/ttyAMA0

  Linux Image and Kernel :

Shields :

Navio 2 :

Target Board : RPi 2

Sensors :

• MPU9250 IMU
• LSM9DS1 IMU

Thanks for digging through the docs!

@ivereninov It would be fantastic to get a NAVIO 2 to Kabir. We have very much a focus on ports this month.

Thanks @mhkabir for putting this together. A few additional bits about Erle-Brain 2 and PXFmini:

Following! I want to contribute. Let me know what i can do. Thanks!

[mhkabir]

@vmayoral @bo-rc @Clouded Everyone please see #3527

The cross-compiler and native build targets work fine now.

Hi Kabir,

Do you think we can give this a try on the RPi2 with the Navio+?

[mhkabir]

@abencomo Yes you can :) Feel free to jump in! Just don't expect any hardware to work just yet.

[bo-rc]

@mhkabir Are we going to take assignments for the drivers?

[gelazanskas]

+1, waiting for PX4 to work with Navio 2

[maxekman]

Following the with great interest!

Just wanted to mention that the link to the RT Linux by Emlid points to the older Navio (1) version, the Navio 2 version (for RPi 3) is here: http://docs.emlid.com/navio2/Navio-APM/configuring-raspberry-pi/

I would also like to know when I can try this out my on rpi2/3
