Hello,
I am running kernel 4.1 in a var-dvk-solo-linux evaluation board from
Variscite.
This is what I get at system start-up:
coda 2040000.vpu: Firmware code revision: 34588
coda 2040000.vpu: Initialized CODA960.
coda 2040000.vpu: Unsupported firmware version: 2.1.8
coda 2040000.vpu: codec registered as /dev/video[0-1]
Apparently, the firmware is being loaded properly although it complains
about that version not being supported.
After queuing some YUV420 buffers with a simple application I perform a
VIDIOC_STREAMON in both the CAPTURE and the OUTPUT interfaces but I get
the following error:
coda 2040000.vpu: coda is not initialized.

---[ end trace 2b0ba71bfb12fec4 ]---
As anyone seen the same issue? Could be related to the "Unsupported
firmware version" complaint?
Do you know where to get the 2.1.5 firmware for the i.MX6D?
Regards,
Javier.
