Re: [meta-freescale] Technical queries on android BSP porting on imx6

[sai lakshmi]

Hi,

Thanks for your reply. I have looked into the community, BSP document on
linux is available but not on android. If you can send me the link of the
BSP, it would be of great help to me.

Thanks & Regards

Re: [meta-freescale] IPU alpha blending problems on mx6

[Olivier Bourgois]

Hi Andrea,

We are facing a similar problem but with the imx6quad plus.  Very similar use 
case, overlaying video onto a QT5 app with gstreamer on second framebuffer but 
with imxeglvivsink and color keying to make the video rectangle overlay.  We 
are using a split-mode LVDS link.  We get the same IPU_INT_STAT_5 and 
IPU_INT_STAT_10 followed by screen freezing.

What I noticed is that if I reduce the size of the second frame buffer to 
around 320x200 with fbset  (just for a test), the system seems to be able to 
cope with the small video overlay.  I am also capable of displaying two alpha 
blended full screen still images by "cat image > /dev/fbx" So it does look like 
there is a bandwidth bottleneck somewhere in the video pipeline.  Note that we 
have the same board also fitted with a standard imx6quad (not plus) and in this 
case things were working but somewhat lagging.

It almost seems to me that there are use-cases where the ipu can't cope with 
two 1080p streams at the same time (one for each frame buffer).  We are also 
still looking for a solution.

In our case we have only the 60Hz LVDS output, I wanted to try lowering to 30Hz 
to see if the problem goes away, but my TFT does not support it.  I have no 
HDMI port on my board.  What refresh rate are you using on HDMI port?  If it is 
60Hz, can you try modifying your video mode to 30Hz to see if it helps in your 
use-case?  This might confirm that we are facing some kind of video pipeline 
bandwidth issue at the IPU.  Alternately or in parallel, does a lower 
resolution say 720p give you the same issue?

Regards

Olivier

Objet : [meta-freescale] IPU alpha blending problems on mx6

Hello,
We use an imx6 quad processor to run a Qt application on fb0, then application 
runs gstreamer pipeline to play video on overlay buffer fb1. Our system was 
previously based on kernel 3.0.35 and using mfw_isink it worked perfectly up to 
1080p. Now we are porting on kernel 4.1.15 with Yocto Morty branch. Qt5.7 app 
on fb0 and play video through gstreamer on fb1 using imxg2dvideosink.
We use alpha blending with separate alpha buffers to uncover only the video 
rectangle on fb1.
In this configuration system is unstable with hdmi turning off and on 
repeatedly giving errors:
[ 1568.833307] imx-ipuv3 240.ipu: warning: wait for bg sync eof timeout
[ 1572.143078] imx-ipuv3 240.ipu: IPU Warning - IPU_INT_STAT_5 = 0x8880
[ 1572.143089] imx-ipuv3 240.ipu: IPU Warning - IPU_INT_STAT_10 = 0x0008
after a while screen blanks definitivelly and i have to reboot.
It seems to strictly depend on local alpha blending since i can replicate the 
issue also by running
 /unit_tests/autorun-ipu. If i use glabal alpha the problem do not appear and i 
can run full screen application and video with 50% blending with no problem so 
it doesn't seem to be a dma shortage.
Already tryed arg dmfc=3.
Could you help me?

Thank you

Depending on the GPU version you're using, DirectFB is not supported.

Basically it's only adding a new device. I know there are some DOC on

As far as I know, it's not working.

There is some code for DTS on the android kernel, but it is not
completely implemented.

Re: [meta-freescale] Change SSH Server Port

[Fabio Berton]

You can create an bbappend to openssh_7.4p1.bb and add your ssh config 
settings. In your openssh_%.bbappend file put:


FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"

and then create a directory openssh with sshd_config file.

The result is these two files:

meta-your-layer/recipes-connectivity/openssh/openssh_%.bbappend
meta-your-layer/recipes-connectivity/openssh/openssh/sshd_config

You can change ssh_config file or add other any file using SRC_URI variable.

Re: [meta-freescale] unable to initialize libusb: -99

[Takashi Matsuzawa]

Hello.

Today I tried testing with the unmodified images.

(just followed the build instruction on README from 
https://github.com/Freescale/fsl-community-bsp-platform), and the result was 
the below.


lsusb on imx61sabreauto board:


2.0 (jethro) - OK

2.1 (krogoth) - NG

2.2 (morty) - NG

2.3 (pyro) - NG

I am curious since it is OK (lsusb correctly list the USB devices) with jethro, 
but NG on krogoth and after.
I may look into the delta but still not sure where to look into.
Any comment/suggestion is welcomed.

Hello.

I am still looking into this, since without USB working the board is les use.

And, I noticed there is an post regarding imx6qdl-sabreauto.dtsi issue 
regarding pca953x control.


https://community.nxp.com/thread/435299

In fact before in the boot log, I see the followings before "Can't register 
ci_hdrc platform device, err=-517" errors.
I an hardly imagine none of the sabreauto board users (on linux-fslc) can use 
USB.   And also I could use USB on NXP release BSP, so board hardware is not 
broken.

If there is a fix patch or workaround known, or if it is my configuration 
problem, I would like to learn.

Hello.

I am trying an image based on morty (2.2) fsl communty BSP on sabre-ai board, 
and see the lsusb -99 error.


Any suggestion/comment on which part of the configuration I should be look into!
(I already googl'ed and found some old questions/answers on libusb -99 errors, 
but I could not figure out if they are just the same as my case or not.)


My issue is that SB is not working (lsusb gives me error), as below.

I checked and make sure CONFIG_USB_EHCI_HCD/CONFIG_USB_XHCI_HCD are there.
