VPU_EncGetVersionInfo failed

[allanmatthew]

I'm using a custom i.mx6Solo board and am having an issue with the vpuenc gstreamer plugin.  I'm able to otherwise use gstreamer plugins like mfw_v4lsink, tvsrc, mfw_isink etc but the vpu does not seem to be working.  When invoking vpuenc with the h.264 codec, I get the following debug error from gst-launch:

0:00:02.613795334  1154   0x389920 ERROR                 vpuenc vpuenc.c:441:vpuenc_core_init: func VPU_EncGetVersionInfo failed!! with ret 1

Looking in my dmesg, it appears that the VPU is recognized as I see:

mxc_vpu 2040000.vpu: VPU initialized

I'm using the 3.10.17ga fsl-image-test yocto image.

I've confirmed that this also happens with vpudec.

Thanks for the help,

I found the problem.  In my device tree, I was setting the VPU power supply to pu_dummy, when it should have been set to a regulator.  Seems to have fixed the issue.

Hi,

I'm facing the same issue, but I am using a i.MX6 Dual (MCIMX6D5EYM10AD).

I have pu_dummy too, and here is what I get in my dmesg:

mxc_vpu 2040000.vpu: VPU initialized

vddpu: disabling

mxc_vpu 2040000.vpu: size=0x4000, page no.=0x2040

mxc_vpu 2040000.vpu: [ALLOC] mem alloc cpu_addr = 0xac080000

mxc_vpu 2040000.vpu: start=0x76722000, pgoff=0x3c080, size=0x7c000

If I understand correctly, it seems that VPU is enabled and initialized, then disabled, and not enabled again...

Allan, can you share your dts part for vpu ?

Thanks,

JM

Hi JM-

I'm not sure I saw the same issue you did, but see my .dts attached.

Hi Allan,

Thanks for this : it works for me too !

I get this line :

0.236680] vddpu: 725 <--> 1450 mV at 1150 mV

And I don't have the line vddpu: disabling anymore.

Follow-up: The Yocto build for 3.0.35 seems to work just fine.  This does indeed appear to be an issue with 3.10.17.

Hi Allan

our 3.10.17 yocto developers are working on link below,

please post issue on meta-fsl-arm mailing list, so that

they could try to assist you.

A bit more information, I turned on VPU debugging in the kernel, and when I run gst-launch with vpuenc I get  the following:

root@imx6dlsabresd:~# dmesg | grep vpu

mxc_vpu 2040000.vpu: VPU initialized

mxc_vpu 2040000.vpu: size=0x4000, page no.=0x2040

mxc_vpu 2040000.vpu: [ALLOC] mem alloc cpu_addr = 0x8c300000

mxc_vpu 2040000.vpu: start=0x766cd000, pgoff=0x1c300, size=0x7c000

Hi Allan

first check that this particular i.mx6Solo has VPU module

(not all processors have it) with i.mx6Solo datasheet.

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6S&nodeId=018rH3ZrDRB24A&fpsp=1&t...

Also please check this issue with ltib

L3.0.35_4.1.0_ER_SOURCE_BSP

You can try to rebuld yocto (check woth documentation inside package

to include VPU divers).

If after that you think that this is specific 3.10.17 yocto problem,

please post issue on meta-fsl-arm mailing list, so that someone familiar with

similar problems could try to assist you.

Thanks chip-

I'm using an MCIMX6S5EVM10AC which does have a VPU.

I've also tried re-building yocto, as well as using an imx6dlsabresd machine type.

My gst-inspect is as follows, indicating that indeed all of the necessary plugins are being built and installed:

root@imx6dlsabresd:~# gst-inspect|grep imx

mpeg2dec.imx:  mfw_mpeg2decoder: mpeg2 video decoder

v4lsink.imx:  mfw_v4lsink: v4l2 video sink

mp3enc.imx:  mfw_mp3encoder: mp3 audio encoder

h264.imx:  mfw_h264decoder: h264 video decoder

isink.imx:  mfw_isink: IPU-based video sink

vpu.imx:  vpudec: VPU-based video decoder

vpu.imx:  vpuenc: VPU-based video encoder

audiopeq.imx:  mfw_audio_pp: audio post equalizer

mpeg4dec.imx:  mfw_mpeg4aspdecoder: mpeg4 video decoder

amrdec.imx:  mfw_amrdecoder: amr audio decoder

aiur.imx: webm: webm

aiur.imx:  aiurdemux: aiur universal demuxer

beep.imx: ac3: ac3

beep.imx: 3ca: ac3

beep.imx:  beepdec: beep audio decoder

beep.imx:  beepdec.vorbis: Vorbis decoder

beep.imx:  beepdec.mp3: MP3 decoder

beep.imx:  beepdec.aac: AAC LC decoder

ipucsc.imx:  mfw_ipucsc: IPU-based video converter

tvsrc.imx:  tvsrc: v4l2 based tv src

v4lsrc.imx:  mfw_v4lsrc: v4l2 based camera src

I will also try a posting on the meta-freescale list.
