Summary
This specification tracks the status of support for the Freescale Babbage board for the Karmic 9.10 cycle.
Release Note
Ubuntu 9.10 has extended support to the Freescale Babbage2 Board. Babbage1 support has been dropped.
Rationale
The Babbage2 board is the next generation of the iMX51 platform, is the target hardware for FSL for this cycle.
Requirements for Implementation
- 2.6.31 series kernel for iMX51 Babbage2 lands in Ubuntu git tree
- redboot (or uboot) sources for the Babbage2 materialize, and are merged into the redboot-imx package in the archive.
- Additional hardware for testing and debugging becomes available
Code Changes
- ubuntu-cdimage
- - Needs to be updated to use need redboot-tools -OR- if we move to u-boot this cycle, modified to create uboot images - Descriptions need to be updated for TO2 support
- linux kernel
- Current codedropped from FSL have support for 7 SoCs, we only support fo the iMX51 - Latest kernel only 2.6.28, kernel team needs to fowardport to 2.6.31
- debian-installer/base-installer
- - Subarchitecture detection will have to be updated to detect the Babbage2's /proc/cpuinfo string
- flash-kernel
- - Subarchitecture detection will have to be updated to detect Babbage2 in addition to Babbage1 - Will need update to new redboot-tools or uboot-tools depending on the state of bootloader support
- iso.qa.ubuntu.com
- - Will need to be updated for imx51 for karmic (requires RT ticket filed, should be done after we have images building)
Migration
- No migration will be supported from Babbage1 to Babbage2. Depending on kernel support, Babbage1 support may remain in 9.10 in an unsupported state
Test/Demo Plan
Normal ARM/Desktop image test cases can be used to test image.
Unresolved issues
- Lack of development hardware for the team (total of four Babbage2's available)
