hello, and one.
we were produce the AM3358 board ready, it is work well with the linux 3.2.0, the LCD is TM150TDSG70(1024x768), the LVDS pixel clock is 56.88MHz.
the fbset information on the linux 3.2.0 as below:
mode "1024x768-28"
# D: 30 MHz, H: 22.322 kHz, V: 27.694 Hz
geometry 1024 768 1024 1536 16
timings 33333 100 120 10 18 100 10
accel false
rgba 5/11,6/5,5/0,0/0
endmode
but now we want to use the GFX, so we are move to AM335x-SDK01.00.00.03, the linux is 3.14.43, other function are work well, but the LCD is flick, and the fbset information as below:
mode "1024x768-0"
# D: 0.000 MHz, H: 0.000 kHz, V: 0.000 Hz
geometry 1024 768 1024 2304 16
timings 0 0 0 0 0 0 0
accel true
rgba 5/11,6/5,5/0,0/0
endmode
i was checked the pixel clock is 56.88MHz by OSC between the AM3358 and the SN75LVDS83.
the DTS as below:
panel {
compatible = "ti,tilcdc,panel";
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&lcd_pins>;
panel-info {
ac-bias = <255>;
ac-bias-intrpt = <0>;
dma-burst-sz = <16>;
bpp = <16>;
fdd = <0xff>;
sync-edge = <0>;
sync-ctrl = <1>;
raster-order = <0>;
fifo-th = <6>;
invert_pxl_clk = <1>;
tft-alt-mode = <0>;
};
display-timings {
1024x768p60 {
clock-frequency = <56880000>;
hactive = <1024>;
vactive = <768>;
hfront-porch = <76>;
hback-porch = <50>;
hsync-len = <50>;
vfront-porch = <12>;
vback-porch = <5>;
vsync-len = <5>;
hsync-active = <1>;
vsync-active = <1>;
de-active = <1>;
pixelclk-active = <1>;
};
};
};
have any suggest to us?
thanks!
