Neither versions (Bionic or Buster) imgs available on this site boot up on my Rock Pi 4 board. I've had it for a week.

 

It does with Debian which reports excellent power and it also boots Android 9.

 

Yes I've tried many thoroughly tested SDs.

 

If you haven't personally tried booting these images as they are on your newer Rock Pi 4 board please don't respond to this message.

All images are tested.

 

Have you followed instructions on the download pages?

1. Provide a log from serial console or take a screenshot

 

Use  USBimager to write SDcard, try different power supply

No need to provide anything. It is most likely a classical problem with SPI bootloader which workaround is written on the download pages. I highly suspect this note:

Erase SPI boot loader and boot from SD/eMMC. That one does not have a delay.

No, its a model B, but that doesn't count - they are identical in this and we had a delay, but not anymore. Its related to the bootloader ... you can search for https://github.com/armbian/build/commits/master to see when this was fixed in case that interests you.

BTW. I am using self made image from latest sources. I am not 100% sure this delay was fixed on the images from the download section ...

The fix for RockPi 4 boot delay is quite fresh.

At this point you can use latest nightly images (built after 3rd of May), build the image yourself or wait for v20.05 ;-)

i tried stop bluetooth.service, yes start up is fast

i try  latest nightly images , it is ok, thanks everyone， armbian is a great job

 

@Igor interesting thing: when i  erase SPI boot loader, board can't boot up, so i update SPI flash with bootloader , the latest images works fine, so ...........

 

next question:   how to rotate screen ? now i just know xrandr, it is not efficient method.
