Device unable to boot
Hi everybody, I've just bought a RockPro64.

Yesterday I wanted to try it out and flashed OpenWRT onto a SD card and powered it.
I was getting a white LED almost immediately and I was able to login using SSH and the web GUI.

Today I wanted to actually setup the board, I tried to boot using the same process and using the same working SD card. I couldn't get any LED expect the green power LED.
I tried reflashing the SD card with OpenWRT again, still nothing.
Tried connecting the HDMI, no signal.
Tried to flash Armbian Buster for the RockPro64. Same thing no HDMI signal and no LED.
I also tried to connect to the board using serial. When I'm trying to use 9600,8n1 I'm getting just an infinite number of `?` in the terminal,
when using 1500000,8n1 I'm getting ``

I tried flashing the OS on two different SD cards.
At first I tried flashing using Etcher on Windows and using PuTTY to connect.

Since that wasn't working, I booted into Linux. Redownloaded the OpenWRT version I previously was able to boot.
Flashed a SD card using:
sudo dd if=./openwrt-21.02.0-rc2-rockchip-armv8-pine64_rockpro64-ext4-sysupgrade.img of=/dev/sdb

Powered the device with the freshly flashed OS.
And tried to get the serial monitor to work using
minimon -D /dev/ttyUSB0 -b 1500000

Still nothing except a long line of missing symbol character (same as PuTTY on Windows), and still no white LED.

I've also noticed the Ethernet port LEDs looks really dull for about 5 minutes then brighten.
I'm using a HW-417 Serial to USB, and I keep the TX cable disconnected from the pin 10 of the PI header, since from what I've read the connecting the TX to pin 10 at boot could cause the board not to boot. Still tried with the pin 10 connected just in case but didn't change a thing.
