Sorry for the confusion, here is the gst log [3] and dmesg + media-ctl [4]

Here you configure a pipeline that ends at ipu1 prpenc capture ...

... and then you try to capture from prpvf, which is not part of a

True, thanks for pointing it.

I actually tried even on video0 which I forgot to post the log [4].
Now I understand I'm trying for wrong device to capture look like
video0 which is ipu1 prepenc firing kernel oops. I'm trying to debug
this and let me know if have any suggestion to look into.

[ 56.800074] imx6-mipi-csi2: LP-11 timeout, phy_state = 0x000002b0

I don't have the hardware but this looks like the host cannot detect the
LP-11 state on the sensor (both wires high?). Some sensors cannot do this
without starting streaming at the same time. I'd expect the same if there
are problems in lane configuration etc.

You mean the lane configurations in hardware? but this sensor is
working with imx kernel. what do you mean by wires here? lanes.

Could you please test this series from Jacopo?

... unfortunately it does not :(

I've been able to test on the same platform where Jagan has reported
this issue, and the CSI-2 bus still fails to startup properly...

I do not have CSI-2 receiver driver documentation for the other platform
I am testing on and where my patches improved stability, but the i.MX6 error
reported by Jagan could be useful to help debugging what's wrong with the
serial bus initialization on that platform.

The error comes from register MIPI_CSI_PHY_STATE of the i.MX6 MIPI_CSI-2
interface and reads as:

0x2b0 : BIT(9) -> clock in ULPS state
BIT(7) -> lane3 in stop state
BIT(5) -> lane1 in stop state
BIT(4) -> lane0 in stop state

The i.MX6 driver wants instead that register to be:

0x430 : BIT(10) -> clock in stop state
BIT(5) -> lane1 in stop state
BIT(4) -> lane0 in stop state

So indeed it represents a useful debugging tool to have an idea of what's going
on there.

I'm a bit puzzled by the BIT(7) as lane3 is not connected, as ov5640 is a 2
lanes sensor, and I would have a question for Jagan here: has the sensor been
validated with BSP/vendor kernels on that platform? There's a flat cable
connecting the camera module to the main board, and for high speed
differential signals that's maybe not the best possible solution...

Also, anyone interested in my mumbling on the ov5640 MIPI bus
initialization, I've collected some thoughts here:
https://paste.debian.net/1031942/

Any comment is of course welcome, and if I have a confirmation that
the Engicam platform works with that flat cable, I'll keep working on
it..

Last time I heard from Jagan he reported that the LP11 timeout issue
was caused by:

commit 476dec012f4c6545b0b7599cd9adba2ed819ad3b
Author: Maxime Ripard <[email protected]>
Date: Mon Apr 16 08:36:55 2018 -0400

media: ov5640: Add horizontal and vertical totals

All the initialization arrays are changing the horizontal and vertical
totals for some value.

In order to clean up the driver, and since we're going to need that value
later on, let's introduce in the ov5640_mode_info structure the horizontal
and vertical total sizes, and move these out of the bytes array.

Yes, I've validated through engicam Linux, [1] before verifying to
Mainline. I have similar board which posted on the website on J5 point
20-Polig connector attached to bus to sensor[2]

Thanks for the link. Can you confirm is your sensor working with
Mainline? we are trying to verify mainline ov5640 sensor here.

Sorry, can’t do it for next two weeks. Is this platform developed in your company? Maybe you can blame the hardware guys... I have had problems with them getting it right in my past experience :)

I have a 4.14 kernel for my i.MX6D/Q using an ov5640 connected in a
similar way as the sabresd and I'm getting similar timeouts.
when executing

media-ctl -l "'ov5640 2-0010':0 -> 'imx6-mipi-csi2':0[1]"
media-ctl -l "'imx6-mipi-csi2':2 -> 'ipu1_csi1':0[1]"
media-ctl -l "'ipu1_csi1':1 -> 'ipu1_ic_prp':0[1]"
media-ctl -l "'ipu1_ic_prp':1 -> 'ipu1_ic_prpenc':0[1]"
media-ctl -l "'ipu1_ic_prpenc':1 -> 'ipu1_ic_prpenc capture':0[1]"

media-ctl -V "'ov5640 2-0010':0 [fmt:UYVY2X8/640x480 field:none]"
media-ctl -V "'imx6-mipi-csi2':2 [fmt:UYVY2X8/640x480 field:none]"
media-ctl -V "'ipu1_csi1':1 [fmt:AYUV32/640x480 field:none]"
media-ctl -V "'ipu1_ic_prp':1 [fmt:AYUV32/640x480 field:none]"
media-ctl -V "'ipu1_ic_prpenc':1 [fmt:AYUV32/640x480 field:none]"

gst-launch-1.0 -v v4l2src num-buffers=1 device=/dev/video0 ! jpegenc
! filesink location=test.jpg

[ 72.799015] ipu1_ic_prpenc: EOF timeout
[ 73.838985] ipu1_ic_prpenc: wait last EOF timeout

When I try to jump directly to 4.19-RC8, I get errors regarding memory
allocation, so I think there might be something else there I am
missing.

Has anyone tried this camera module on a 4.14 kernel? I noticed there
are a bunch of driver updates, and I was hoping there might be some
patches that could be be backported to the 4.14.y stable branch.

thanks for any suggestions to try.

You're routing through imx6-mipi-csi2 pad 2, which is CSI-2 virtual
channel 1, so make sure the ov5640 is transmitting on that channel,
see virtual_channel module parameter.

I would suggest backporting all the ov5640 commits. You can also
backport the imx-media commits, but that shouldn't be the cause
of the timeouts you are seeing.

Thanks, am I wrong or jpegenc is a software JPEG encoder?

I was interested in options for capturing the JPEG frames as produced
by the sensor. I'm not even sure it is possible at all.

Please share the errors. I am using v4.19-rc7 without issues.

Yes, try to backport the recent ov5640 developments on your kernel
version. There are a lot of fixes there, and I don't think there is
any dependency on new developments on the v4l2 framework you don't
have in v4.14 (I might be wrong though).

In case something breaks when cherry-picking patches or when building,
please share and someone might help (I have recently backported those
changes to a v3.14 kernel, so I might help too).

Thanks

First, I want to apologize for the spam. I don't normally want to ask
for hand-holding, but after spending 4 solid days on this, I'm getting
frustrated, and I've tried to read the instructions, and the technical
reference manual is huge and somewhat overwhelming.

Once I get my hardware working and I develop a better understanding of
how this system works, I'll be more than happy to volunteer to help
test patches on my hardware.

I am not sure I fully understand how the media-ctl handles the
routing. I just basically copied what I could find from some
documentation. I looked for some documentation but I wasn't able to
find much. Maybe you can point me to some.

I can share with you some of my device tree, and I'll try to explain
my connections. Firstly, I have an i.MX6Q and i.MX6Q which share the
same device tree.

The CSI pins on the OV5640 camera go to i.MX6 pins:
CSI_CLK0M / CSI_CLK0P,
CSI_D0M / CSI_D0P,
CSI_D1M / CSI_D1P,

CSI_D2 and D3 pins on the processor are all floating, and CSI_REXT is
grounded through a 6.04k pull-down resistor.

I am not sure if these technically translate to CSI0, CSI1, or CSI2,
but I assumed the CSI2 since that's how the SabreSD board appears to
work.

The ov5640 is connected to i2c3 with the following tree entry:

ov5640: camera@10 {
compatible = "ovti,ov5640";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ov5640>;
reg = <0x10>;
clocks = <&clks IMX6QDL_CLK_CKO>;
clock-names = "xclk";
DOVDD-supply = <&mipi_pwr>;
AVDD-supply = <&mipi_pwr>;
DVDD-supply = <&mipi_pwr>;
reset-gpios = <&gpio3 26 GPIO_ACTIVE_LOW>;
powerdown-gpios = <&gpio3 27 GPIO_ACTIVE_HIGH>;

port {
ov5640_to_mipi_csi2: endpoint {
remote-endpoint = <&mipi_csi2_in>;
clock-lanes = <0>;
data-lanes = <1 2>;
};
};

I will be the first person to admit, I don't understand how the
clock-lands and data-lanes interact with the mipi_csis and the camera,
but I tried to match the sabresd board device tree.

For the MIPI_CSI interface, I wasn't sure which ports are the proper
reference. Looking at the sabresd board, I used it as an example. I
wasn't sure if port0 and reg 0 were the right options.
&mipi_csi {
status = "okay";

port@0 {
reg = <0>;
mipi_csi2_in: endpoint {
remote-endpoint = <&ov5640_to_mipi_csi2>;
clock-lanes = <0>;
data-lanes = <1 2>;
};
};
};

There was one section of the sabresd board that I wasn't sure I
needed, because I am new to this camera stuff. I wasn't thinking I
needed it, but I copied it because the sabresd board had it. I know
it has two cameras, but the interaction between the csi interface and
the ipu isn't clear to me.

&ipu1_csi1_from_mipi_vc1 {
clock-lanes = <0>;
data-lanes = <1 2>;
};

I am not 100% certain the following is correct, but I tried to disable
unwanted features to help save power, but it's quite possible it's
interfering with the settings i have above.

&ipu1_csi0 {
status = "disabled";
};

&ipu2_csi0 {
status = "disabled";
};

&mipi_dsi {
status = "disabled";
};

I am ok with simple streaming to the screen. I'm ok with converting
to video. At this point, I'm trying to just simply see the camera
work. :-)

I ported the entire ov5640 driver, but there appear to be some v4l
changes which preclude me from copying the whole driver. I was hoping
to use as close to stock 4.14 LTS kernel since 4.19 isn't quite done
yet. (I 'think' 4.19 will be an LTS kernel if I'm not mistaken, so
this kernel is open for discussion if we must transition to it)

My i.MX6 board is running some tests now, but I'll try to build
4.19-rc8 and share some logs.

I first went through the git commit logs for the ov5640 and tried to
grab anything with the word 'fix' in the headlines. I'll try this
afternoon, to get a better feeling for which fixes were ported. In
theory, I can go and request certain fixes to be backported too, but I
want to make sure they actually work before I waste people's time.

For the folllwing example, I am just trying to stream to a fakesink,
toward the bottom, there are a couple errors ''Failed to allocate
required memory' and 'Buffer pool activation failed'.

I configured the pipeline as follows:

media-ctl -l "'ipu1_ic_prpenc':1 -> 'ipu1_ic_prpenc capture':0[1]"

I am hoping I am doing this correctly.

I admit I have copied the pipeline setup script I used from Jagan's website

Here it is for reference:

Fabio,

Unfortunately, no. I built the rootfs based on Jagan's instructions
at https://openedev.amarulasolutions.com/display/ODWIKI/i.CoreM6+1.5

I tried building both the 4.15-RC6 kernel, a 4.19 kernel and a 4.14 LTS kernel.

Using the suggested method of generating the graphical display of the
pipeline options, I am able to enable various pipeline options
connecting different /dev/videoX options tot he camera. I have tried
both the suggested method above as well as the instructions found in
Documentation/media/v4l-drivers/imx.rst for their respective kernels,
and I have tried multiple options to capture through
ipu1_csi1_capture, ipu2_csi1_capture, and ip1_ic_prepenc capture, and
all yield a broken pipe.

libv4l2: error turning on stream: Broken pipe
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Could
not read from resource.
Additional debug info:
gstv4l2bufferpool.c(1064): gst_v4l2_buffer_pool_poll ():
/GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
poll error 1: Broken pipe (32)

I can hear the camera click when I start gstreamer and click again
when it stops trying to stream.

dmesg indicates a broken pipe as well..

[ 2419.851502] ipu2_csi1: pipeline start failed with -32

might you have any suggestions?

thanks,

This -EPIPE error might mean you have a mis-match of resolution, pixel
format, or field type between one of the source->sink pad links. You can
find out which pads have a mis-match by enabling dynamic debug in the
kernel function __media_pipeline_start.

Also make sure you are attempting to stream from the correct /dev/videoN.

Following Jagan's suggestion, I tried to make sure all the resolution
and pixel formats were set the same between each source and sink.

media-ctl --set-v4l2 "'ov5640 2-0010':0[fmt:UYVY2X8/640x480
field:none]"
media-ctl --set-v4l2 "'imx6-mipi-csi2':1[fmt:UYVY2X8/640x480
field:none]"
media-ctl --set-v4l2 "'ipu1_csi0_mux':2[fmt:UYVY2X8/640x480
field:none]"
media-ctl --set-v4l2 "'ipu1_csi0':2[fmt:AYUV32/640x480 field:none]"

I have graphically plotted the pipeline using media-ctl --print-dot
and I can see the proper video is routed, but your dynamic debug
suggestion yielded something:

imx-media capture-subsystem: link validation failed for 'ov5640
2-0010':0 -> 'imx6-mipi-csi2':0, error -32

I am assume this means the interface between the camera and the csi2
isn't working. I am going to double check the power rails and the
clocks. i can hear it click when activated and deactivated, so
something is happening.

It's what I expected, you have a format mismatch between those pads.

Is the mismatch something I am doing wrong with:

media-ctl --set-v4l2 "'ov5640 2-0010':0[fmt:UYVY2X8/640x480 field:none]"
media-ctl --set-v4l2 "'imx6-mipi-csi2':2[fmt:UYVY2X8/640x480 field:none]"

or is there something else I need to do? I just used Jagan's suggestion.

Yeah, that looks correct, media-ctl _should_ automatically propagate the
format at 'ov5640 2-0010':0 to 'imx6-mipi-csi2':0. What version of
media-ctl are you using? If you have an older version of media-ctl tool
that doesn't propagate formats from source->sink pads, you'll have to
explicitly set the format at 'imx6-mipi-csi2':0, and at all the other
sink pads in your pipeline. Better yet, upgrade! :)

Could you try to verify the actual format configured on the sensor?
(media-ctl --get-v4l2 "'ov5640 2-0010':0").

Depending on the driver version you are running, you might be affected
by different regressions.

> or is there something else I need to do? I just used Jagan's suggestion.

I suggest you to update the driver version to the last one available
in the media-tree master, or at least try to backport the following
commit:
fb98e29 media: ov5640: fix mode change regression

If it turns out the format and mode configured on the sensor do not
match the one you want.

Thanks

That got me past one hurdle. Wtih your help, I was able to confirm
the mis-match of the modes between the sensor and the csi1 source. I
applied the patch as you suggested, but now I get a new error.

[ 295.294370] imx6-mipi-csi2: LP-11 timeout, phy_state = 0x00000230
[ 295.300681] ipu1_csi0: pipeline start failed with -110

I am going to go through various patches to the imx framework and
ov5640 driver to see if I can find the solution, but if you have
suggestions as to which fixes are appropriate, I'll test those. If I
can get this working, would it make sense for me to submit some
requests with kernel-stable to backport some of these commits to 4.19
and if applicable, 4.14 too?

Here you go:
bad1774 media: ov5640: Fix timings setup code
aa4bb8b media: ov5640: Re-work MIPI startup sequence

Please update your ov5640 driver to the last version available on
linux-media master repository. There have been a looot of developments
and fixes recently (and I would be happy to know if they have helped
you)

Just get what's on linux-media master tree.

Sure it will (even if I'm not familiar with the procedure used to tag
patches to be applied to stable. I would just apply everything that's
on the latest media tree)

Keep us posted!

Thank you everyone for your help. I pulled the linux-media master and
built it, and it works perfectly from what I can tell. I'll go through
the patch list and see what's back-port-able to 4.19. I noticed that
just copying the ov5640.c driver breaks the build on 4.19.0, so I'm
going to focus on just patches labeled 'fix' on both the ov5640 for
now.

I appreciate everyone's help, and Iearned a lot about the v4l system
in the process.

Does anyone know when the media branch get's merged into the mainline
kernel? I assume we're in the merge window with 4.19 just having been
released. Once these have been merged into the mainline, I'll go
through and start requesting they get pulled into 4.19 and/or 4.14
if/when appropriate.

This should happen in 4.20-rc1, which will probably be out next Sunday.

I sent an e-mail to stable with a list of a variety of patches for the
ov5640 to be applied to 4.19.y So far all looks pretty good, but I
think I found on minor bug:

If I attempt to change just the resolution, it doesn't take.

Initial read
media-ctl --get-v4l2 "'ov5640 2-0010':0"
[fmt:UYVY8_2X8/640x480@1/30 field:none colorspace:srgb xfer:srgb
ycbcr:601 quantization:full-range]

Change resolution
# media-ctl --set-v4l2 "'ov5640 2-0010':0[fmt:UYVY2X8/720x480 field:none]"

Read it back
# media-ctl --get-v4l2 "'ov5640 2-0010':0"
[fmt:UYVY8_2X8/640x480@1/30 field:none colorspace:srgb xfer:srgb
ycbcr:601 quantization:full-range]

However, if I change the resolution AND the format to something other
than UYVY2x8, the resolution changes. I can then change the format
back to UYVY and capture and stream video at 1080p and 720x480.
I can work around this, but I thought I'd mention it. I was trying to
figure out a patch to apply to the mailing list myself, but I wasn't
able to fix it quickly.
