weston.ini conflicts in AGL - Imx8 build

manizillion · ‎08-12-2019

I see the following errors while building with the following bistro and bitbake configuration, failing at last stage of the build. Some suggestions to solve this error would be helpful.

DISTRO=imx-agl-wayland MACHINE=imx8mqevk source nxp-setup-agl.sh -b bld-agl
bitbake agl-image-weston

Hello Manivannan s,

The AGL demo is provided “as is”, as a proof of concept, and it was tested only on the i.MX6Q so no support is provided for this demo and it hasn’t been tested on the i.MX8M.

You can find the readme here:

http://git.freescale.com/git/cgit.cgi/imx/meta-nxp-agl.git/tree/README.txt?h=krogoth

And the repository on the following git server:

http://git.freescale.com/git/cgit.cgi/imx/meta-nxp-agl.git/

My apologies for the inconvenience.
Regards,

Hi Gusarambula,

thanks for the reply, since we are trying to AGL on imx8, we could build agl-image-minimal and bring up on it. But with agl-image- Weston and agl-image-ivi the issues are coming,

Is there any workaround solution you can suggest such that we build the agl-image-weston (imx8mqevk) configuration without errors, Or you conclude to say that it wont work for imx8?

Thanks

Mani

Hi,

Have you built images for other target as well.

I found issues even in building for agl-minimal. qemu and lingpg related errors that what I am getting. I am doing it for imx8 and host is ubuntu 20.04.

Regards,

Vis

Hello Manivannan s,

The i.MX8 does have support for wayland Weston graphics and should be technically capable of running the demo, if you put time into figuring out the dependencies.

It seems that there is a conflict on the Weston version. Since the demo is set for i.MX6Q it could be that a fixed Weston version is preferred and it’s conflicting with the i.MX8 version. You could try to resolve this albeit you would need to be careful that the rest of the demo can run on the i.MX8 supported westion version.

I hope this helps!

Hi Gusarambula ,

Is there any similar issues seen with imx6sabre ? recently i received a suggestion mail (below in bold) which said we can follow the same steps which were done for imx6 sabreauto and make it work for imx8. If so can you please share link or reference steps which was done on imx6 so that we could follow same for our platform?

whatever tree you’re using that has a “nxp-setup-agl.sh” script isn’t mainline AGL and seems likely to be a NXP provided thing. If that’s the case, you’ll need to ask them for help, as we’ve no idea what’s in that tree.

If you can live with using the open source etnaviv driver instead of the binary Vivante driver, you could try adding a machine definition for the imx8mqevk to the AGL master branch. It shouldn’t be too hard if you follow what’s done for one of the i.MX6 boards like the sabreauto.

gusarambula · ‎08-29-2019

Hello Manivannan s,

All information on this demo is available in the links I shared. As you may see documentation for this demo is limited so there is no much information on the steps followed to enable the AGL demo on the i.MX6 Auto board.

The suggestion of adding the imx8mqevk MACHINE configuration to the AGL master branch may work although it’s also not a trivial process. You would need to find the imx8mqevk.conf files (and all files required by this .conf file) and add them to the AGL master branch and then edit the image recipes accordingly.

In theory is possible and sounds straightforward but it would require some work and knowing how Yocto works.

We have a BSP porting guide, which is a bit general:

https://www.nxp.com/docs/en/user-guide/i.MX_BSP_Porting_Guide_Linux.pdf https://www.nxp.com/docs/en/user-guide/i.MX_BSP_Porting_Guide_Linux.pdf

And there is also the Yocto BSP Developer’s Guide, although it includes only very general instructions.

https://www.yoctoproject.org/docs/current/bsp-guide/bsp-guide.html

I hope this helps!

Thanks for your replies sir, will work towards it just one more question,

How to add NXP's meta-fsl-bsp-release layer to the tree to pick up the new 4.19 linux-imx kernel and weston 6.0.0.imx

tree is imx-linux-thud

manizillion · ‎09-01-2019

Also ,

I would like to know what steps are followed to build.

Should we follow the build steps for imx8 similar to steps mentioned in AGL website like given below ?

agl-distro:agl-raspberrypi [Automotive Linux Wiki]

OR

Should we modify the steps similar to one given in NXP website ?

meta-nxp-agl - i.MX Yocto Project AGL Demo Layer

gusarambula · ‎09-02-2019

Hello Manivannan s,

You may add a new layer on the conf/bblayers.conf file on your build directory. You can check that the layer was added by running:

$ bitbake-layers show-layers

However, keep in mind that there may be dependencies and conflicts between the layers. As the approach you may start with either the AGL website or NXP website and work from there. I would probably recommend the AGL website at least for the majority of the recipes, and the kernel from the NXP website (which you would need to adapt for AGL).

I hope this helps!

manizillion · ‎09-05-2019

Hi Gusarambula,

Just a questions, if i have to include 4.19 linux-imx kernel to the AGL build steps, how to do it ?

Will adding meta-fsl-bsp-release layer to the /build/conf/bblayers.conf automatically take 4.19 linux-imx kernel while building.

We were following the steps from this Jira ticket raised by us.

[SPEC-2748] Apps install errors( afm utils, DBUS api), Imx8 platform, agl-image-minimal, - Automotiv...

How to enable Vivante graphic drivers? Please share us some reference sources if any team has done it.

appreciate your support,

Thanks and Regards

Mani

gusarambula · ‎09-16-2019

Hello Manivannan s,

I see that there has been some follow up on the Jira AGL Development. Hopefully they may provide further help.

As for the GPU drivers I would recommend referring to the i.MX Linux Reference Manual which is part of the BSP Releases documentation. If you are using a Community BSP kernel you may use the closest BSP Release kernel version as reference. Adding the meta-fsl-bsp-release layer will change the default kernel as the layer has a higher priority but you may force the preferred version or try lowering the meta- bsp-release priority.

I hope this helps!

manizillion · ‎08-18-2019

Hi Sir,

Your response has been very helpful, can you share little more details on Howto. is there any web reference to solve this issue which you know ?

Thanks and Regards
