Hw: CODA960, Fw: (0x0000), Version: 0.0.0 I just tried with the same kernel, and the above download, converted with the program in the referenced mail, and I get this: coda 2040000.vpu: Firmware code revision: 36350 coda 2040000.vpu: Initialized CODA960. coda 2040000.vpu: Unsupported firmware version: 2.1.9 coda 2040000.vpu: codec registered as /dev/video0 md5sum of /lib/firmware/v4l-coda960-imx6q.bin: af4971a37c7a3a50c99f7dfd36104c63 Note that I so far tested the kernel driver with the older firmware version 2.1.5: coda 2040000.vpu: Firmware code revision: 32515 coda 2040000.vpu: Initialized CODA960. coda 2040000.vpu: Firmware version: 2.1.5 md5sum of /lib/firmware/v4l-coda960-imx6q.bin: f58119103d94adcd5c2d5070d65ebd26 I was under the impression that I had obtained this version from the very same URI previously, but I am not 100% sure about that. Also there is yet another version available from http://www.freescale.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-3.10.17-1.0.0.bin, which currently contains firmware version 3.1.1: coda 2040000.vpu: Firmware code revision: 46056 coda 2040000.vpu: Initialized CODA960. coda 2040000.vpu: Unsupported firmware version: 3.1.1 md5sum of /lib/firmware/v4l-coda960-imx6q.bin: 2a087c2e4043c3c3a4104765a33b12aa regards Philipp -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
