OMAP5 DSI activate with Ubuntu

Other Parts Discussed in Thread: PMP

Hello:

I have a OMAP5432 EVM board, install Ubuntu with the kernel of 3.8.4 downloaded form the ti-glsdk_omap5-uevm_6_03_00_01, now I want to use DSI to display ubuntu on the lcd. I have set the right parameter in panel-taal.c files, and change the setting in omap5-evm.dts like:

&dsi1 {
	taal {
		compatible = "tpo,taal";

		lanes = <
			4       /* clk + */
			0       /* clk - */
			5       /* data1 + */
			1       /* data1 - */
			3      /* data2 + */
			0       /* data2 - */
			        /* data3 + */
			        /* data3 - */
			       /* data4 + */
			      /* data4 - */
		>;

		vdds_foo-supply = <&ldo2_reg>;

		gpios = <&gpio6 23 0>;	/* 183, reset */	 
	};
};

then get the dtb files for booting. now the ubuntu can start because I can type some command in minicom,
but no image on my lcd display. is there something else I need to set? Like the boot.scr files? the resolution of the
display is 480*800. Thank you!

Best regards

Hi Ryan,

Take a look at the following patches, i suggest you implement you display as it is done here.

Hi Boyko:

Compare with the patches, I found they are almost the same with the dtl file in my kernel. For me I only did a little changes:

I changed :

lg4591_pins: pinmux_lg4591_pins {
    pinctrl-single,pins = <
    0xf2 0x8 /* perslimbus2_clock.gpio6_183 OUTPUT PULLDOWN | MODE0 */
    >;
    };

into

taal_pins: pinmux_taal_pins {
		pinctrl-single,pins = <
			0xf2 0x8	/* perslimbus2_clock.gpio6_183 OUTPUT PULLDOWN | MODE0 */
		>;
	};

and

&dsi1 {
    lcd {
    compatible = "ti,lg4591";

into

&dsi1 {
	taal {
		compatible = "tpo,taal";

Because the parameters are changed in panel-taal file, so I think the lg4591 file is not correct. but the display still cannot enable, is there still something wrong?

What does show in your console log? And did you observe any communication on the dsi lines to the display?

please check your .config and see if the taal driver is not build as module. further more are you using linaro sources?

Boyko

Hi Boyko：

Yes, I build the taal driver into the uImage with Yes, not M.

I use the linaro source with Ubuntu 12.04 but the kernel I get from the TI.

Best regards

Ryan

Hi,

Can you share what changes you did in your board file? perhaps something there is incorrect.

Regards,

Boyko

What you ask is really what I want to know at this moment, because after I compile the kernel and get the uImage, I cannot find any board file that has been compiled (no .o file at all). At the beginning I think the dss-common.c is the board file, then I try to add some comment so that it can display on the minicom, but nothing I can check. So now I am also feel strange how to find this board file.

Best Regards

Ryan
