Thanks for this explanation isimobile.

So basically we need to look for an ICS camera lib for the Tegra 2 specifically?

So my investigation leads to the following devices that use a Tegra 250 T20 chipset:
Acer Iconia Tab A100, A200 and A500, Asus Slider, LG Optimus Pad, Avionic Design Tamonten Processor Board, Exper EasyPad, Notion Ink Adam tablet, Olivetti OliPad 100, Point of View Mobii 10.1, ViewSonic G Tablet, Motorola Xoom, Toshiba AC100, Toshiba Folio 100, ASUS Eee Pad Transformer, Advent Vega, Hannspree Hannspad, Aigo n700, CompuLab Trim-Slice nettop, Dell Streak 7, E-Noa Interpad, Malata Tablet Zpad, MSI 10-inch (250 mm) tablet, Toradex Colibri Tegra 2, Toshiba Thrive tablet, Samsung Galaxy Tab 10.1, T-Mobile G-Slate, Lenovo IdeaPad Tablet K1, Lenovo ThinkPad Tablet, Velocity Micro Cruz Tablet L510, Dell Streak Pro, Zyrex Onepad SP1110, Zyrex Onepad SP1113G, Sony Tablet S

=> The Motorola Xoom is for example in this list and received an ICS upgrade (and more importantly, the back and front camera work on it).

When I look at the camera specs for this device:
BACK CAM : 5 MP
FRONT CAM : 2 MP

Maybe we could use this camera lib from this ROM? Maybe we could get at least the front camera to work if we're lucky.

I've extracted this ROM for the Motorola Xoom and taken the lib's for the camera from it.
I've then replaced the /system/lib/libcamera_client.so, /system/lib/libcameraservice.so, /system/lib/libnvmm_camera.so, /system/lib/hw/camera.goldfish.so, /system/lib/hw/camera.stingray.so with the ones from the Xoom ROM. Is this enough or do I need other files as well?

When I start the camera it doesn't say that it can't connect to the camera anymore like previously, but the app crashes a little while later. I've attached a logcat for investigation. Someone an idea? We need a kernel modification?
