Can someone help me understand UART output from Beelink GT1 Ultimate tv box (no HDMI signal, endless UART loop)?:

[arminmal]

I have Beelink GT1 Ultimate tv box. One day some app froze and I turned power off and on. After turning power on, I had no signal on TV and it’s been like that ever since. I contacted Beelink and they gave different 2 images (GT1_709D0.img and GT1_708D0) to try flashing with USB Burning Tool. However, USB Burning Tool always gets stuck at 7% formatting with the following error:

error: [0x32030201]Uboot/Get result/DiskInitial error.

I tried every possible combination (different ports, power on/no power after reset, force erase, etc). The only positive is that the box is detected by USB Burning Tool.
I also tried making bootable sd card with Burn card maker using those images but it didn’t help either – UART output provided.
Can someone tell me based on the UART logs below what is going on and suggest steps to debug/resolve it?
The interesting part is that every time UART output stops at these two lines and when I googled those lines, it seems other people tv boxes logs, where I found these lines, there is more output following them but in my case it always stops at those lines:

emmc/sd response timeout, cmd8, status=0x1ff2800
emmc/sd response timeout, cmd55, status=0x1ff2800

Here is the UART output with normal operation – endless loop:

Thanks in advance for your help

[ReaperMan]

A little info for my learning, I'm not tech enough to figure what you use to retrieve the logs?


Probably little help to you.
I guess you already tried another 1. T.V., 2. HDMI cable, 3. Power supply?

[arminmal]

No offence but I need someone who understand these those logs and spot a log line(s) which indicates possible problem. I mentioned that I tried trivial things like changing cables and ports etc.

[anteros]

Uboot was erased,so infinite of loop of '
LOOP:1;EMMC:0;READ:800;SD:800;USB:8;'

UART could fix or amlogic USB burning tool.
