Is M your sd card? It does look incorrect. Good spot.
Anything on the SD card will be erazed, so backup anything you need!
To install openwrt, you need to download the image from the firmware selector
I'd say you should use ext4
You need to unzip the gz file. 7zip can do this.
Then write the image using etcher (https://etcher.balena.io/) or similar.
See if that works for you.
You guys won't believe it....
The UART issue was the power supply that shipped with the T6.
The grounding was so bad on it that it was causing a ton of noise over the UART connection.
Switching to another (higher quality) 12v power supply allows me to read the output from the serial console.
I can read the console at reasonable baud rates after changing out the power supply.
I think there is some miscommunication here.
I can boot OpenWRT via SD card just fine using the method you mention above.
What I am attempting here is to write the image from the bootable SD card to either the internal EMMC or NVME drive and boot from there given how quickly SD cards can fail.
Are you saying that I should be prompted to install the OS onto the internal storage or something similar when I load in the SD card?
I have the older supported board without a USB-C UART port.

I put the entire serial console output here: https://pastebin.com/A31C3ZRw
Just to be clear, this is the exact process of what I did prior to the kernal panic logs above.
For comparison, here are the serial logs of FriendlyWRT booting successfully: https://pastes.io/friendlywrt-serial-console-logs
Just tried flashing the EMMC from FriendlyWRTs web GUI.
Here are the logs when I rebooted the T6:

Just as a sanity check, I used the same process with Armbian and it boots with no problem:
Maybe it has something to do with the kernel version?
I was taking a look at working OS images and found they're all using 6.1 instead of 6.4. Maybe that is the issue?
I've been comparing the boot process on internal memory vs SD card: https://www.diffchecker.com/UUU5aoLw/
Seems that something happens to break the GPT table when the image is loaded onto the internal memory.
I think I figured something out.
The issue seems to be with a corrupted GPT table after writing the image to the T6.
You can't install directly to EMMC internal memory, but you can copy the disk image directly to a NVME drive.
