Hi batoub,

    What kernel version you wish to work with e-CAM driver ?

    Please find the 2.6.33 patch file in the attachment. And the error you got is due to not availability of lm355 led flash chip in e-cam board.
 But your camera related features will work correctly. Please test the driver with the provided sample application capture.elf.

Thanks and regards,
Ananth.

First econ provide only a patch for kernel 2.6.30 so I need to use this
kernel :/ then I have a strange bug using when I load the driver. It seem
like i2c is not working at all?
