Are you looking at the same LED light sequence when you power up your board both with and without an SD card inserted. You may have damaged the SD card reader. I strongly doubt putting an alien OS SD card in your card reader would have damaged the board.
Thank you for the reply.
Yes, I have tried both the factory image(from pine64) and Armbian image. None will be able to make my board boot.
When connect to power, the white and red LED are always on. There is no blinking. I wasn't able to observe any difference whether the board is powered on with or without an SD card.
In fact, the only difference it makes, when an SD card is inserted, is the UART will print something from the 1st stage bootloader (as shown above).
