According to i.MX_6Dual6Quad_SABRE-SD_Linux_User's_Guide.pdf, I use oneiric as filesystem on my customer board.I use HDMI as displayer,system can boot well,but can not login in.

The following is my bootargs:

 

video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24  root=/dev/mmcblk0p1 rootwait rw

 

After system boot,only part of the login UI is displayed,as my attachment login.jpg. In login  box,I can type linaro,and the enter,after a while,the display goes to all black and back to login.jpg soon.

I think HDMI driver is OK,when I enter CTRL+ALT+F1,the command line intercface is well as show in cmd.jpg.

 

Who can tell me what to do next?
