TMDX654GPEVM: Touchscreen problem

Hello,

What version of the SDK are you building?

When you use the out of the box software, does the touchscreen respond as expected?

Regards,

Nick

thanks to reply

i used lastest bsp version from openembedded.org

and create-SDcars.sh from Ti website

i tested touchscreen that prebuilt-image from Ti demo

and touchscreen is work very well

i write same mean to korean please use to google transfer.

i hope you are more understand this issue

안녕하세요 읽어주셔서 감사합니다.

오픈임베디드의 가장 최신의 Bsp SDK를 사용하고있습니다. 또한 TI에서 제공하는 prebuilt-image를 통해 터치스크린의 동작을 확인하였습니다.

감사합니다.

Hello Jeawhan,

Is your question resolved? Or do you need more help?

If you need more help, then tell us specific information about the Yocto build that does not have a working touchscreen.

Regards,

Nick

Hello Nick

I need more help to this problem

I used Ti-BSP from http://git.yoctoproject.org/cgit/cgit.cgi/meta-ti

And I built am65xx-evm.conf

I posted the script in the first post.

I Checked MACHINE_FEATURES += "touchscreen"

And then I can made Yocto Build image.

And I was download PROCESSOR-SDK-LINUX-AM65X from http://www.ti.com/tool/PROCESSOR-SDK-AM65X

I used  create-SDcars.sh included in the PROCESSOR-SDK-LINUX-AM65X

but I had problem and posted this forum  "TMDX654GPEVM: I Can't Boot up Yocto Custom Linux" and solve problem

finally I can boot up Yocto image. but didn't working touchscreen.

I already boot up Prebuilt image from Ti, when touchscreen working

thanks to read, and if you want more information please Reply Say to me

if I solve myself, I will write solution.

I wait your Reply, have a good day

Hello,

I wanted to point you to this documentation:

http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Overview_Building_the_SDK.html

This should build the a "exact" SDK provided by TI and should be your first step. 

Can you please try this to see if a bootable image created by this process enables the touchscreen to work?

Thank you.

hello RonB

i do your solution.

so i built 

MACHINE=am57xx-evm bitbake arago-base-tisdk-image

and working well

but this image is just command line image so i built 

MACHINE=am65xx-evm bitbake arago-core-tisdk-bundle

because docs said arago-core-tisdk-bundle is Full SDK version

but I get some compile error 

ERROR: arago-tiny-image-1.0-r0 do_rootfs: The postinstall intercept hook 'update_udev_hwdb' failed, details in /home/chung/yocto/tisdk/build/arago-tmp-external-arm-toolchain/work/am65xx_evm-linux/arago-tiny-image/1.0-r0/temp/log.do_rootfs

ERROR: Task (/home/chung/yocto/tisdk/sources/meta-arago/meta-arago-distro/recipes-core/images/arago-tiny-image.bb:do_rootfs) failed with exit code '1'

I was just following your docs link.

how can i solve this problem?

thanks to read my reply

Again, the touchscreen worked fine on a prebuilt Linux image provided by TI


Also, refer to the manual provided by you and run MACHINE = am65xx-evm bitbake arago-base-tisdk-image.

But currently
When building with MACHINE = am65xx-evm bitbake arago-core-tisdk-bundle, I get an error like the answer above. 
Please confirm this problem and I want to answer the first question.


If you have any additional information you would like to ask for, please request a quick response.

For additional information, leave the build and conf information for the first question in this post as follows:

Hello RonB

I deleted the existing tisdk and ran the manual again.
The build command was then executed with MACHINE = am65xx-evm bitbake arago-core-tisdk-bundle.
After about 15 hours of compilation, I noticed that the hard disk is out of space.
My hard disk had 350Gb of free space before compiling.
I wonder if this is normal when I run the above build command.

I will wait for your reply.

Ps.
This comment was made on 11/24 and the following comment was made on 11/22.
Therefore, the comments below (written on 11/22) are the work I did before deleting tisdk described above, and I recompiled after deleting tisdk to compile in a clean environment.

As a further consideration, the white background yocto I posted first did not perform the calibration of the touch screen.

I checked your manual (software-dl.ti.com/.../How_to_Guides_Target.html and found that calibration is needed.

If so, how do I run it initially like the matrix image provided by Ti when I run yocto?

My guess is that I have to put the corrective code in conf / bblayers.conf, but I couldn't find a description of it, and I couldn't find it because the bblayers.conf inside tisdk was written in a huge folder. I would like to ask for a verification and my method.

hello Nick

I waiting your solution

please give me answer

thanks to read

have a good day

Hello,

It would really be best to get a TI build working on your set up so that you can evaluate something working. The Weston (which includes touchscreen support and calibration) config is quite complex and may have many other problems if deviating away from the SDK. 

In the above build, it seems that you ran out of disk space. For a complete build, you may need 500GB to 1TB of hard disk space available.

If you want to do some exploring, please take a look at sources/meta-arago/meta-arago-distro/recipes-graphics/wayland/weston.

Thank you.

Hello RonB

I have already confirmed that the touchscreen works by using the prebuilt image of the SDK provided by ti.
What I want is to operate the touch screen on my Yocto image. Please let me know the manual or how to do this.

thanks
