Yes, I have seen these - My expertise lies primarily in boot loader development, but I am keen to help with testing and data collection (I simply do not have enough time to start deep RE efforts atm) The other issue I have is that these efforts are primarily geared towards the 3D hardware and not the video decoding units. For example, the A10 use the Mali core, but it also has it's own core (CedarX) for video stream decoding Regards, Graeme _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
