i have buy it from ali express after that i made bootable images of armbian, kali , and android and then triying to boot but it didnt boot it shows no display only green light blinks tell me the solution
Have you checked the console on the UART? See serial-console
yes i have chacked it but not detecting tell me what is next
Are you using a SD card? I would suggest the Armbian or Radxa to start with.
When you boot the with the Serial console attached you should see output. Perhaps you can copy and paste the output here.
Also, just to double check have you tried the Getting Started? That details how to make an SD card image.
