isle,
Thank you for reply.

I thought that there is a kernel configuration or DTS description for the dual display.
I searched firefly-rk3288.dts & firefly-rk3288 -reload.dts in the kernel but found no clue to achieve it easily.
Though there are "DUAL", "NO_DUAL" and "ONE_DUAL" for rockchip,disp-mode in DTS fb section, they don't seem related to the dual display I want.

Do you mean that I should modify kernel source code like rk_fb.c ?
Doesn't Firefly supply source code for the dual display ?
