Hi everyone,
I recently purchased a fan so I could finally check out my board I had been meaning to boot up, and I have not been able to get it booted via SD or eMMC. It just hangs with the green light on, no matter which power supply I tried. It shows up in maskrom, however the RKDevTool fails at any interaction, including reading capability. I plugged it into my UART adapter and I get the below results every time it is plugged in. Can anyone offer any advice?
R Version V1.08 20220617

I purchased this from ameriDroid and waited beyond their 4 week return window unfortunately.
