Boot Problems, LEDs lit continuously - Facecreator - 04-28-2018
Hello, please excuse my bad english, come from germany. I got my ROCK64 today, with original power supply. Have written several images on different SD cards. But he just does not boot. All 3 LEDS are lit continuously and the TV says "no signal". (have tried different HDMI cables). Can you help me?
Many Thanks

The green LED stays lit when there is power to the board, the white and red LEDs do different things in different images.
Do you know if the network LEDs on the ethernet port blink at all?

Thanks for the answer. No, the LEDs on the LAN port stay off.

What images have you tried to use?
Also what did you use to write to sdcards?
RE: Boot Problems, LEDs lit continuously - pfeerick - 04-29-2018
And do you have an ethernet cable plugged into the rock64? ('cause the lights won't blink if there's no cable plugged in ...
!)Plus what evilbunny said! ^^
RE: Boot Problems, LEDs lit continuously - Facecreator - 04-29-2018
Yes the lan cable is plugged in
, have tried it with etcher and the pine64installer. Have tried the Debian and Android versions and the spi u boot flash. Nothing happens 
RE: Boot Problems, LEDs lit continuously - CricketeerOne - 04-29-2018
Same problem... Used Etcher and Pine Installer on both Mac and Windows. Different SD cards. Different monitors. Also tried Android, Armbian, Debian, and Ubuntu Xenial

Hello, I have now tried the ROCK64 read out serially. I use a FTDI FTD232 (This one) for this purpose. I have Linux installed on my Raspberry Pi. I also tried with Windows and Putty. Short on my approach:
1.) Connect Rx from the Rock64 (pin 10) to the Tx of the adapter
2.) Connect Tx from the Rock64 (pin 8) to the Rx of the adapter
3.) Connect ground together (pin 6)
4.) Plug adapter into USB port (LED on the adapter lights up)
5.) Open terminal and enter: "dmesg | tail -n 10"
6.) He tells me that the adapter is connected to ttyUSB0 (Screenshot)
7.) Then I enter: "sudo minicom -s -D / dev / ttyUSB0 -b 1500000 --color = on"
8.) Then set 1500000 8n1 in the settings and turn off flow control
9) Leave the config and it appears the surface, now I turn on the Rock64 and nothing happens except the 2 funny characters.
10.) Do I have to jump any pins?

As a last resort download and unzip the Debian image from here https://www.armbian.com/rock64/ and use Win32discimage to write to your SD card. Eject the SD card, pop it into your Rock64 and let it work away. It worked for me when I was having problems with other images
RE: Boot Problems, LEDs lit continuously - Facecreator - 05-01-2018
Have it again under windows tried with another program. I also tried the Armbian version. In the screenshot you can see what the program shows me when I connect the rock. I doing anything wrong?
