help! how to checkout an old version in omap zoom gingerbread branch???

[UGlee Ma]

We licensed an omap3630 android bsp from a partner. But they just provides the source code, without any git/repo information.

Now we know they started their work from omap zoom gingerbread branch. so I tried:

repo init -u git://git.omapzoom.org/platform/omapmanifest.git -b gingerbread

and after repo sync, I found the android version is 2.3.5, not 2.3.4 shown in the code we got.

then I tried

repo init -u git://git.omapzoom.org/platform/omapmanifest.git -b gingerbread -m gingerbread-xxxxxx.xml

but after that a repo sync gave us only vanilla gingerbread.

I also tried to checkout a previous commit in ./repo/manifests, but it doesn't work either, since the default.xml file contains no commit info.

Is there any way to checkout to a history version so I can diff the files to figure out from which version our partner started their job?

Any advices and suggestions would be greatly appreciated.
