Are there any updated and more clear/concise guidelines on how exactly to flash an OS (Ubuntu 22.10 from Libre distro in this case) to the EMMC I just installed on my renegade? I have been trying to follow the instructions for the Le Potato as there are no specific instructions for the Renegade; to no avail. I have tried on Windows as well as Mac OS (and Linux/Ubuntu in a VM, my only board natively running linux is actually this renegade 
so I was only able to try linux through my VM) and have had no success. The EMMC would really make a pivotal performance difference on this board and I would really like to be able to take advantage of that. Thanks in advance!
Just boot up the board on Linux, download the image, extract it, and dd the image to mmcblk0.

Worked flawlessly and took no time at all! I am very pleased with the performance boost! Currently writing this from the Renegade running Ubuntu Lunar Lobster natively off of the EMMC; and loving it 
Thank you for such a quick and helpful response!! That kind of customer service/support is really unheard of these days!
We are releasing 2023.04 by next week.

Love that! I have had no issues so far, very stable performance for me
I’ve spent the day trying to flash a microSD and install in on my Renegade, with no success.
I downloaded and flashed some CI images (the Debian 12 one, and Ubuntu – both base and server ones) with the following command:
sudo dd of=/dev/disk4 status=progress bs=4M if=./ubuntu-22.04.2-preinstalled-server-arm64+roc-rk3328-cc.img
Same with other images. When I plug the microSD in the Renegade and turn it on, nothing happens. The green light does not show, but the red light is always on.
Am I missing something?
Did you extract the image?
Always dd images with bs=1M
You are destroying your MicroSD card without it if your OS does not merge writes.
What the heck is disk4?
