Hi, I've been trying to get accelerated graphics up on imx53 - unfortunately, causing lots of crashes and little else.
I think the problem is that so far, the only version of the graphics driver that has been released is for Gingerbread, and it simply doesn't work with ICS. However, some of you have much more experience than me with making sense of binary blobs, so if someone has some spare time, feel free to look. ;) I've attached the script I'm using to push the binary driver into system.tar.bz2.
I've looked at their kernel sources and gralloc tree, and it looks like we have everything we need there - but of course I could be wrong.

I guess you tried using your scripts with our gingerbread builds (last release was 11.11)... and that didn't work?

Applying it to our stock 11.11 build can't work because back then we were on a kernel that didn't have the right support module (amd-gpu). Building the current kernel into the 11.11 release and then running the script on it might work and is on my list of things to do if there's spare time, but I didn't get around to doing that yet.

Bero,
We do have amd-gpu in 3.1 kernel. What's specifically wrong with that module?

Nothing (or at least nothing we're aware of yet). The 11.11 release shipped with 2.6.38 and didn't have amd-gpu yet.

This is lt-3.1-ubuntu branch though. The problem is how you sync the android kernel w/ our lt-3.1-imx5/lt-3.1-ubuntu?
