Supporting WUXGA(1920x1200) resolution on Android 5.1 SDK?

Posted at 6/27/2017 16:55:44      View:5581 | Replies:4        Print      Only Author   [Copy Link] 1#
Hi,

I'm wondering that Firefly-RK3288 reload can support WUXGA(1920x1200) resolution output?
I've check that there is no option for 1920x1200 in [Settings] -> [Display]  -> [HDMI mode] menu.
For reference, I'm using a monitor via HDMI cable for displaying.

If I need to modify SDK [Firefly-RK3288 Android 5.1], would you let me know how to do it, please?

Thank you in advance.

I have added a custom resolution 1280x1024p@60Hz to kernel/drivers/video/rockchip/hdmi/hdmi-lcdc.c:

        { {        "1280x1024p@60Hz",        60,        1280,        1024,        108000000,        248,        48,                38,        1,        112,3,        FB_SYNC_HOR_HIGH_ACT | FB_SYNC_VERT_HIGH_ACT,        0,        0        },        4,        0,                                                        1,        OUT_P888},

but dmesg outputs a wrong pixel clock:

dclk:118800000>>fps:66 instead of 108000000

I think it can be fixed in struct rk3288_apll_table[] in kernel/drivers/clk/rockchip/clk-pll.c ?

But I don't understand those values (_mhz,        nr,        nf,        no, ...)
Can anybody tell me the values to support 108000000 pixel clock?

Thank you.
