Thanks. I believe in your method is right way. In addition, I want to know meaning of these setting parameters in the fex file. so We can modify it for other condition. Do your have any web link about A20 fex file?

after changing .bin file

Thanks for your reply. I am according to your method, the hdmi screen is work. The hdmi screen displays the text control terminal. I can adjust screen resolution in the terminal by input command like "a10disp changehdmimodeforce 4" . But after that, dhcp does not work. I use "ifconfig " to check eth interface. I can see the eth0 and it's MAC address,but no IP address. I guess that DHCP is disable. Another question, if I reboot the system, I must input command "a10dip" again for adjust to screen resolution. How can I fix it? If it should be fixed by modify some file, What file should I modify? Thanks!

Hi: I have an olimex-mirco A2O board. I have already run A20-OLinuXino-MICRO Debian Jessie with kernel 3.4.103+ release 12 on it, and everyting is ok. I use the HDMI screen, because the kernel sets vedio output is HDMI 720p by default. when running , i can see the debian GUI in the screen. After that, I got the Armbian_5.20_Micro_Debian_jessie_3.4.112.iso, and dd the image into the SD card. The board can work. I can login into Debian by ssh. In boot procedure, I can see the boot information on the HDMI screen, but after boot finished, the hdmi screen only display blue. Because the kernel does not output signal to HDMI interface. I input the command by SSH terminal: a10disp changehdmimodeforce 4 Then i got prompt is: hdmi is not enable I read the getting started and other documents on armbian.com. Because English is not my native language, so I don't understand the documents very well. I just guess, I must config the display setting for enable HDMI in the uboot setting. But I don't konw how do I config it? Who can give me some hint? Thanks very much!
