Porting Android to a new platform can be a challenge. Here are some resources to start with that:

Processor Support


Most ports of Android are to ARM-based platforms.


  • Mentor Graphics and Texas Instruments support Android on OMAP processors via the project
  • See also Android on OMAP, which has a very thorough listing of issues faced in initially porting Android to OMAP


Mentor Graphics did a port of Android to MIPS.

There is a whole well-developed project for Android on x86.


At least one major product (Sony Internet TV) is reported to be x86-based. Intel has a team of developers working on Android issues. See Mark Gross' presentation from ELC 2010 for some tips from them about using Android

Individual Platform Support

For Nexus One

Unlocking the phone

Bryan Swetland says: (here)

All Nexus One devices have an unlockable bootloader (% fastboot oem unlock), which, once unlocked will allow you to reflash the boot partition (kernel + ramdisk), system partition, etc.

Full kernel sources are available here:;a=shortlog;h=refs/heads/android-msm-2.6.29-nexusone (make mahimahi_defconfig to configure just like the production kernel). We're in the process of rebasing up to .32, on our way to .33 and beyond.

Serial port access

There are some serial port pins available on the micro-USB connector, which you can access if you have the right hardware.

See this discussion on xda-developers for detailed information and links.

Brian Swetland says: TTL level (~3.3v?) serial is present on the D+/D- pins of the micro USB connector whenever VBUS (usb +5v power) is not present. This is physical UART1 (ttyMSM0). In standard builds the FIQ kernel debugger runs there. You'll have to disable the FIQ debugger and enable the serial device in your kernel config if you want to use it as a regular serial port.
