Support matrix

We are working on basic support for all of our core modules and extension boards. This matrix gives you the current status.

We've also collected a "test specification" where you can see how we are testing.

GIT access

We have dedicated GIT repositories for U-Boot, Linux kernel and uClinux distribution. Additionally, there's a repo with some useful scripts.

We update our GITs from time to time from the official sources, and contribute patches for our core modules back to the official sources.

If you want to learn something about GIT, the fast version control system, have a look at this page (but disregard the OpenEmbedded stuff).

Here is how you can check out our GIT repos locally:

git clone git://git.becom-group.com/git/blt-scripts.git blt-scripts.git
git clone git://git.becom-group.com/git/linux-kernel.git linux-kernel.git
git clone git://git.becom-group.com/git/u-boot.git u-boot.git
git clone git://git.becom-group.com/git/uclinux-dist.git uclinux-dist.git

Scripts (blt-scripts.git):

• build-u-boot.sh: Builds U-Boot images for all core modules, including those for UART boot (for processors that support it)
• build-uclinux.sh: Builds uClinux images for all core modules
• build-all-in-1-images.sh: Builds the u-boot+uImage.[bin|ldr] files
• clean-all.sh: Cleans all GIT repositories (Be careful: Your changes are not killed, but new files are!)

Tools support

• Instructions for flash programming with the gnICE or gnICE+ low-cost JTAG
• Configuration files for the PEEDI JTAG
