Can you please be more explicit with the SDK versions you are referring to?

Hello Robert,

I am out of the office until 1/22. Please expect delays in reply.

-Josue

Robert,

On the new image, do you see at least a grey screen?

Can you let me know what dtb you are using?

I do not think the LCD is enabled by default in the newer images..  I am double-checking with our dev team.

For sure the Matrix application is no longer supported.

Please see the release notes here: https://software-dl.ti.com/processor-sdk-linux/esd/AM57X/09_03_06_05/exports/docs/devices/AM57X/linux/Release_Specific_Release_Notes.html#release-09-03-00

-Josue

yes it is a light grey background..  I will review the release notes to see what was remove, but I would thing the boot screen would show but maybe that was removed.

Here is the start of the boot seems like there is an issues with some warning/errors. Reimage a couple time same results. Note the model shows Beagleboard, seem wrong. the UENV.txt file has no defined variables in it - should it?

Thanks for any help

Rob

ok, thanks, questions: it looks just like it does when power is just turned on, not the grey you are showing?

I can stop/start weston but I see this  in the restarting - [13:36:10.000] BUG: layer list is not empty after shutdown. Calls to weston_layer_fini() are missing somwhere.

below is the Weston /start after stop then restarting - seems fine except the above bug

I do see weston task in the list of task though

is there something that I can run to see something on the display or driver code to use in the image to verify things (display)?

Robert,

Can you clarify the above statement? you see the same screen or not? Do you see the date and the weston shell symbol?

Can you see a mouse when you connect one via USB?

Can you share the overlay you are using?

you could run the GPU examples under /usr/share/qt5/examples/gui:

root@am57xx-evm:~# cd /usr/share/qt5/examples/gui
root@am57xx-evm:/usr/share/qt5/examples/gui# ./openglwindow/openglwindow
MESA: info: Loaded libpvr_dri_support.so

and you should see the following:

-Josue

Screen is not the same as yours.

Not sure overlay question means

Ran program as stated and no display (see below) 

root@am57xx-evm:/usr/share/qt5/examples/gui/openglwindow# ./openglwindow
qt.qpa.wayland: Creating a fake screen in order for Qt not to crash
MESA: info: Loaded libpvr_dri_support.so

mouse does show up that it was loaded in the termal (Putty) nothing on screen

fyi..am57xx-evm-linux-rt-06.03.00.106.img.zip this image which was create in 2019 works fine

Seems like the latest version has big issues around this area?

fyi..Test the 2019 image and the mouse work fine in this image

Robert,
2019 image should be fine. I believe the default image for the newest SDK does not have the correct DTS loaded for enabling the LCD screen on the EVM.
So my question is essentially what DT source is being used? 

You might have to use a different DT source file in order to see the screen enabled, and I believe this is an overlay file or .dtbo file 

Should be this one: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm/boot/dts/am57xx-evm.dtso?h=ti-linux-6.1.y

I myself do not have the bandwidth to test right now but I can probably get around the end of next week or the week after.

-Josue

Hi! thanks for the input I'll look at it, but traveling last couple of days should be back on it later today or tomorrow

Robert,

No worries, safe travels!

Thanks, I trying to fine all the link for to get the file to build.. Seems more complicated then I would hope - any help with location image source files?

Robert,

You can download the SDKs at https://www.ti.com/tool/download/PROCESSOR-SDK-LINUX-AM57X/09.03.06.05

Or clone the Linux source https://git.ti.com/git/ti-linux-kernel/ti-linux-kernel.git. You could also do something to the extent of https://stackoverflow.com/questions/61587133/cloning-single-file-from-git-repository.

The LCD overlays are already present in your root image.

-Josue

Thanks, I need to get my Linux box up and look at it. From what I read it need to be built with Ubuntu 14, that really old?

Yes, SDK 6.3-8.2 is tested using Ubuntu 18.04 and the newer SDKs are all tested in Ubuntu 22.04.

-Josue

cool, then 22.04 is closer to the newest - thanks..

BTW: have you have a change to look at it or is that another week or so out?

Robert,

I haven't had a chance to try it out. My evm does not have an LCD screen on it. The dev team reported that this was working on their end during testing. 

I can look into getting the LCD screen for mine, but I t will be a week or so.
