Yocto project support

[kubiznak_petr]

When is there gonna be a Yocto project support for Vybrid, as it is already in progress for i.MX? Any details are appreciated. Thanks.

As mentioned above I inserted two layers as meta-fsl-arm & meta-fsl-arm-extra. There yocto building is done successfully but at booting time it is giving System halted massage after kernel boot. Please get the total kernel logs below.

Board using: phycore vybrid (pcl052)

Host side command used for building:

          source ./oe-init-build-env

          git clone https://github.com/Freescale/meta-fsl-arm-extra.git -b dizzy

          git clone https://github.com/Freescale/meta-fsl-arm.git -b dizzy

Edited local.conf with MACHINE ??= "pcl052" and bblayers.conf and that is looking like below.

-----------------------------------------------------------------------------------------------------------------------------

# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf

# changes incompatibly

LCONF_VERSION = "6"

BBPATH = "${TOPDIR}"

          bitbake -u goggle core-image-minimal

After building successfully got the tar ball of RFS. Copied to SD card. Extracted it. Executed "sudo ln -s sbin/init ." & "sudo chown root ."

Helllo Anindya,

A few thoughts come to mind:

-Are you using dizzy branch for your other meta-layers? You will want to do this if you have not already, and rebuild

-I am unsure of your process for extracting the rootfs to the SD card. Can you try 'sudo tar -xvf /path/to/rootfs -C /path/to/SD/card/partition'? Can you also try DDing the SD card image produced by your Yocto build to your SD card?

Thanks,

Tony

Hi Tony,

Actually previously I was building the kernel separately using poky toolchain and rootfs taken from yocto. But now I used yocto kernel which I built using yocto build system and it is working fine. I found some modifications between yocto kernel and externel kernel source which I downloaded from "ftp://ftp.phytec.com/products/PCL-052_Cosmic-Vybrid/Linux/PD13.1.0/MCC_Demo/". Though this version of kernel is working fine with buildroot, openWRT but not working with Yocto.

Any way, thanks for giving some quick suggestions.

Thanks & regards,

Anindya

Hello Petr,

We have added Vybrid Tower support (machine name twr-vf65gs10) to the meta-fsl-arm Yocto project layer, and the Phytec phyCORE Vybrid (pcm052), Phytec Cosmic+ Vybrid (pcl052), and Device Solutions Quartz Vybrid (quartz) to the meta-fsl-arm-extra layer. Let me know if you have any questions.

Thanks,

Timesys Support

[kubiznak_petr]

Hi Timesys Support,

Thank you for your reply. Can you please point me to some related sources and/or documentation?

Thanks,

Petr

[timesyssupport · Accepted solution]

Hello Petr,

Sure. Here is a link to the sources for the meta-fsl-arm layer:

https://github.com/Freescale/meta-fsl-arm

And a link to the meta-fsl-arm-extra layer:

https://github.com/Freescale/meta-fsl-arm-extra

Finally, here is a link to the Yocto Project Quick Start guide, which has instructions to get you up and running with an initial build:

http://www.yoctoproject.org/docs/current/yocto-project-qs/yocto-project-qs.html

Thanks,

I just gave this a try on my pcm052. Worked pretty much out of the box. Great work!

The only think I had to change was:

meta-fsl-arm/conf/machine/include/imx-base.inc line 121:

KERNEL_IMAGETYPE = "zImage"

to

KERNEL_IMAGETYPE ?= "zImage"

With this change I could specify KERNEL_IMAGETYPE = "uImage" in my local.conf. The pcm052 u-boot is not configured to support bootz, so I have to use uImage.

[kubiznak_petr]

Perfect, thank you!

Hello Ragan_Dunham,

May you comment on our plans, please?

Thanks, Naoum Gitnik.

[Ragan_Dunham]

We have partnered with timesyssupport for Linux support on Vybrid and they will be more than happy to help you out.  We have no plans to support a community BSP for Vybrid in Yocto.

Best Regards,

Ragan
