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
