I want to make a video-player which will be using full acceleration of hardware decoder of F1C100s

I decided to go COMPLETELY DIFFERENT WAY than other people who are f** their brains with this chip / IC for last 10 years
(I've already read a lot of posts about video-playback - all of them useless, especially they looks crapy now in 2025)

so what i did :

I've bought a "video post card" which use THIS board:
https://www.eya-display.com/evdo-quick-start/

there are different screen sizes, the maximum which such board could play (and I have it) - is 10.1" and 1024x600 pixels
video runs smoothly and with sound!

NOW the most crazy part :

as I said - i want to make CUSTOM player and it must be VERY small, so I've decided to use Lichee Pi Nano
https://wiki.sipeed.com/hardware/en/lichee/Nano/Nano.html

and instead than "writing and compiling new code"
- i just de-soldered FLASH CHIP IC from that post card board and soldered it to Lichee Pi Nano
(on both boards it's SOIC8)

but after power-on of Lichee Pi Nano I have this image on the screen
(that's a Lichee Pi Nano connected to cable of LCD of esp32s3 dev-board)

as I understand there must be some GPIO connected to 3.3v or something like this
(without it - the board thinks it runs on battery and it's 0 (zero) charge level , so it not powers-ON)

if anyone knows - PLEASE LET ME KNOW WHAT GPIO TO CONNECT

if don't - buy the same board and try to find this GPIO
(you could find it on aliexpress or taobao)

it will be THE BEST solution of video-playback FOR ALL OUR COMMUNITY
rather than brainf** with all that half-running source-code
