coda 2040000.vpu: firmware request failed

coda 2040000.vpu: firmware request failed

[Jagan Teki]

Hi,

I'm observing firmware request failure with i.MX6Q board, This is with
latest linux-next (4.12) with firmware from, [1] and converted
v4l-coda960-imx6q.bin using [2].

Log:
------
coda 2040000.vpu: Direct firmware load for vpu_fw_imx6q.bin failed with error -2
coda 2040000.vpu: Direct firmware load for vpu/vpu_fw_imx6q.bin failed
with error -2
coda 2040000.vpu: Direct firmware load for v4l-coda960-imx6q.bin
failed with error -2
coda 2040000.vpu: firmware request failed

I've verified md4sum and VDDPU as well, hope these look OK.

# md5sum /lib/firmware/v4l-coda960-imx6q.bin
af4971a37c7a3a50c99f7dfd36104c63  /lib/firmware/v4l-coda960-imx6q.bin
# dmesg | grep regu | grep -i vddpu
[    0.061552] vddpu: supplied by regulator-dummy

Did I missed any, request for help?

There is no need to do the conversion with current code.

The error code is -ENOENT, so the firmware binary is not found where the
firmware loader code is looking. That could be caused by the coda driver
being probed before the file system containing the firmware binary is
mounted. Have you tried compiling the coda driver as a module
(CONFIG_VIDEO_CODA=m)?

Note that converting the NXP provided firmware is not necessary anymore
since commits a1a87fa3a0cf ("[media] coda: add support for native order
firmware files with Freescale header") and 2ac7f08e3075 ("[media] coda:
add support for firmware files named as distributed by NXP").

Also there are newer firmware binaries available, see
https://patchwork.linuxtv.org/patch/42332/

Philipp

Yes, true unless it is module firmware files can't get by coda

# modprobe -a coda
[   24.474662] coda 2040000.vpu: Firmware code revision: 36350
[   24.480556] coda 2040000.vpu: Initialized CODA960.
[   24.485415] coda 2040000.vpu: Unsupported firmware version: 2.1.9
[   24.493494] coda 2040000.vpu: codec registered as /dev/video[0-1]
