NW 07:10 PM Software Development: RE: AM62X GPU Support: Sorry, I have muddied the waters.
We are on 10 sdk from you guys for mitysom. (moving to 10.1 should be no problem).
We are on 9.3 sdk from ti for beagleboard x15.
Thanks,
Nathan Nathan Wright
JC 07:07 PM Software Development: RE: AM62X GPU Support: Note that you linked the 57x Processor SDK instructions. The Am62x version does mention the meta-toolchain-arago-tisdk

NW 06:55 PM Software Development: RE: AM62X GPU Support: Thanks Bob,
I'll try the (what I thought was the older) image method. I saw a posting from TI on e2e (an FAQ iirc) that stated they were moving to populate_sdk. Nathan Wright
BD 06:12 PM Software Development: RE: AM62X GPU Support: Nathan and Tim,
It may be easier to try to fit into TI's way of doing things. They use @bitbake meta-toolchain-arago-tisdk@ to build the toolchain (instead of @populate_sdk@) which you may be able to extend to make your modifications... Bob Duke

TT 08:51 PM Software Development: RE: AM62X GPU Support: Hi Bob,
We did the above and it does get the driver on target. However, when we run populate_sdk those libraries don't make it into the SDK. What do we need to do to get those libraries into the SDK so we can cross compile Qt for targ... Tim Troester
JC 03:46 PM Software Development: RE: AM62x Enable UART2: Note to capture some of this information, we made a wiki page for it. https://support.criticallink.com/redmine/projects/mitysom_am62x/wiki/Example_-_uart2_Serial_CONSOLE Jonathan Cormier

JC 05:02 PM Software Development: RE: We have lost our frame buffer on AM62x: Great, good to hear Jonathan Cormier
NW 04:55 PM Software Development: RE: We have lost our frame buffer on AM62x: In attempting to gather that info, I saw that there were some upstream changes to the devkit dts file that our copy did not have.
After syncing our dts with the devkit dts, the frame buffer is back!
Thanks for your help. Nathan Wright
JC 02:31 PM Software Development: RE: We have lost our frame buffer on AM62x: Thanks Nathan, thats progress. Can you send me your dts/dtb and defconfig? Jonathan Cormier
NW 01:28 PM Software Development: RE: We have lost our frame buffer on AM62x: Hi Jon,
I have restored pvrsrvkm to the target by adding libgles2 recipe to the image. Nathan Wright

NW 08:43 PM Software Development: RE: We have lost our frame buffer on AM62x: Gasp! Eureka, how did I lose those? Nathan Wright
JC 08:36 PM Software Development: RE: We have lost our frame buffer on AM62x: Can you check to see if the GPU driver is loaded? If you've been building custom kernels outside of yocto, its pretty easy to lose the gpu driver and that can break the /dev/fb0 Jonathan Cormier
NW 08:27 PM Software Development: We have lost our frame buffer on AM62x: Hi guys,
We've been focusing a lot on our legacy am57x board in our layer.
So it is highly likely that I somehow broke this in the am62x portion.
I guess I am looking for help on where to start.
Basically, I've got no /dev/fb... Nathan Wright

Thank you for the explanation.

AG 03:07 PM Software Development: RE: GPIO pins and muxing them as pull down: Hi Tim!
The pins GPMC_AD0 (GPIO0_15) and GPMC_AD1 (GPIO0_16) are pulled up on the SOM, and GPMC_AD2 (GPIO0_17) is pulled down on the SOM. This is because these GPIOs are also bootmode pins.
From the "AM62x Carrier Board Design Gui... Alex Gieson

TT 11:09 PM Software Development: GPIO pins and muxing them as pull down: Hi,
We were hoping to get some clarification on the issue below for our own understanding. This isn't a problem for us, but we wanted greater understanding in case there are accommodations we need to make on our version of the carrier... Tim Troester
JC 03:52 PM Software Development: RE: AM62x Enable UART2: Yup looks good Jonathan Cormier
TT 03:51 PM Software Development: RE: AM62x Enable UART2: Jonathan,
Thanks for the additional info. I didn't see your response before I submitted mine. However, it looks like we are on the same page with the solution.

TT 03:41 PM Software Development: RE: AM62x Enable UART2: Bob,
Thanks for the response. I was getting ready to reply saying that I was able to get it working. Here is what I did in case it helps others.

JC 03:39 PM Software Development: RE: AM62x Enable UART2: I'm not sure why but it seems like setting the serial alias is required.

BD 03:02 PM Software Development: RE: AM62x Enable UART2: Tim,
What you have shown looks OK. Can you share your entire device tree file ? Nathan has access to our private project if you prefer to post the information there. You could also share your boot log and the output of @cat /proc/tty/... Bob Duke

NW 07:27 PM Software Development: RE: AM62X GPU Support: Thanks! Nathan Wright
TT 04:17 PM Software Development: AM62x Enable UART2: Hi,
On the AM62x how do we enable UART2 during the Yocto build? We have created our own machine variation of k3-am62x-mitysom and created a dts file for it per the wiki instructions you provided. We thought we need to add this... Tim Troester

BD 04:35 PM Software Development: RE: AM62X GPU Support: Hi Nathan,
Short answer: adding the "@ti-img-rogue-driver@, @wayland@, and @weston@" recipes to your image should bring in everything you need to enable the GPU. If you don't need wayland/weston, take a look at the long answer to man... Bob Duke

NW 06:11 PM Software Development: AM62X GPU Support: Hello again,
What recipe (or distro feature) do we add to our image to enable graphics acceleration on the MITYSOM-AM62X?
Thanks,
Nathan Nathan Wright

LS 06:05 PM Software Development: RE: Can not enable WL1837 Wi-Fi: Hello Jonathan
For my current project I don't need Bluetooth, but it would be good to test it for future applications.
If you could suggest a reference design I would appreciate it.
Thanks and Best Regards
Lucas Lucas Andre Silva

JC 07:49 PM Software Development: RE: Can not enable WL1837 Wi-Fi: Note for a new design, I'd recommend swapping to a m.2. e-key connector as it will provide much more compatibility with wifi/bt modules of all brands and allow some flexibility if chip shortages happen again. I can provide a reference de... Jonathan Cormier
JC 07:04 PM Software Development: RE: Can not enable WL1837 Wi-Fi: Hi Lucas,
Good to hear.

LS 05:10 PM Software Development: RE: Can not enable WL1837 Wi-Fi: Hello Jonathan,
Thanks again, we can confirm that the overlay is loaded and that the interface is up.
