TMDSSK3358: How the LCD pins are assigned by the device tree?

Xavier Ramon Vilamu
Prodigy 80 points
Part Number: TMDSSK3358

Tool/software:

Hi,

I bought the AM335X-EVMSK to test some components. One of the components I'm interested in is the TFT screen. The starter kit uses NHD-2.4-240320CF-CSXN#-F the PINS connected to Processor are

I revised the DTS file:

			AM33XX_PADCONF(AM335X_PIN_GPMC_AD8, PIN_OUTPUT, MUX_MODE1)	/* gpmc_ad8.lcd_data23 */
			AM33XX_PADCONF(AM335X_PIN_GPMC_AD9, PIN_OUTPUT, MUX_MODE1)	/* gpmc_ad9.lcd_data22 */
			AM33XX_PADCONF(AM335X_PIN_GPMC_AD10, PIN_OUTPUT, MUX_MODE1)	/* gpmc_ad10.lcd_data21 */
			AM33XX_PADCONF(AM335X_PIN_GPMC_AD11, PIN_OUTPUT, MUX_MODE1)	/* gpmc_ad11.lcd_data20 */
			AM33XX_PADCONF(AM335X_PIN_GPMC_AD12, PIN_OUTPUT, MUX_MODE1)	/* gpmc_ad12.lcd_data19 */
			AM33XX_PADCONF(AM335X_PIN_GPMC_AD13, PIN_OUTPUT, MUX_MODE1)	/* gpmc_ad13.lcd_data18 */
			AM33XX_PADCONF(AM335X_PIN_GPMC_AD14, PIN_OUTPUT, MUX_MODE1)	/* gpmc_ad14.lcd_data17 */
			AM33XX_PADCONF(AM335X_PIN_GPMC_AD15, PIN_OUTPUT, MUX_MODE1)	/* gpmc_ad15.lcd_data16 */
			AM33XX_PADCONF(AM335X_PIN_LCD_DATA0, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_DATA1, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_DATA2, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_DATA3, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_DATA4, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_DATA5, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_DATA6, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_DATA7, PIN_OUTPUT, MUX_MODE0)

			AM33XX_PADCONF(AM335X_PIN_LCD_DATA9, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_DATA10, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_DATA11, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_DATA12, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_DATA13, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_DATA14, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_DATA15, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_VSYNC, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_HSYNC, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_PCLK, PIN_OUTPUT, MUX_MODE0)
			AM33XX_PADCONF(AM335X_PIN_LCD_AC_BIAS_EN, PIN_OUTPUT, MUX_MODE0)

How is the display PIN linked to the processor PIN? For example, how to be the processor PIN corresponds to the DB0 PIN?

Thanks,

    Hi Xavier,

    I have assigned your query to our expert. While he is out of office, could you get started, referring the following DT:

    1. https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm/boot/dts/am335x-evmsk.dts?h=ti-linux-6.1.y#n723 (Helps setup the Pin mux and LCDC node)

    2. Timing is defined here: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/drivers/gpu/drm/panel/panel-simple.c?h=ti-linux-6.1.y#n2927 (LCDC specific timing) 

    Best Regards,

    Suren

    Thanks Suren,

    I want to connect NHD-2.4-240320CF-CSXN#-F to Texas processor and the connection tree is different and not included in the kernel support list. 

    I need to understand how to assign the PINs and how to add the parameters to the Kernel. Luckily, I noticed that the driver is included in the Kernel.

    I am waiting for your colleague to be able to solve my doubts.

    Regards

    Hi Xavier,

    My colleague is out of office for a week. Please expect a response when he returns to office in 10 days.

    Apologies for the delay.

    Best Regards,

    Hi Krunal, 

    Yes, I know how to assign the PINs with pinmux tool but I need to know how these pins are used by drivers.

    The starter kit LCD uses 8RGB, DR, DG and DB. My question is how the system knows the PIN AM335X_PIN_LCD_DATA0 is DR0, if this corresponding PIN with DR0. How to change this PIN order?

    In a previous comment, Suren shared a file and I show this value:

    bus_format = MEDIA_BUS_FMT_RGB888_1X24.

    This value is what links the pins according to the order in which they are added in the devicetree?

    Thanks, 

    Xavier

    Hi,

    Yes your understanding is correct. Also, here is the init code for the LCDC driver where it reads to bus formats: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/drivers/gpu/drm/tilcdc/tilcdc_drv.c?h=ti-linux-5.10.y#n169

    Hi, 

    Thanks for confirming it. When I plug the new display, will the OS detect it and auto-configure, or do I need to configure some OS files to make it work?

    Where can I find documentation on how to set up new screen?

    Thanks,

    Hi,

    I am assuming you are planning on connecting a LCD panel. If that's the case, there is no EDID information that gets passed between the driver and LCD panel. The driver will use the timing information defined in panels-simple.c to generate the appropriate clock and data signals. We don't have any documents but you can refer to our DTS: 

    1. Panel: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm/boot/dts/am335x-evmsk.dts?h=ti-linux-6.1.y#n190

    2. LCD: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm/boot/dts/am335x-evmsk.dts?h=ti-linux-6.1.y#n723

    Ok, thank you.

    In July, I will receive the LCD and LCD Adapter to connect and test the configuration options.

    Hi Krunal, 

    Finally, I have the PCB with LCD and Texas processor connected. I charged the driver but when started the system I didn't show information about a new display or driver in /var/log/message. How to debug the LCD configuration?

    Thanks,

    Hi,

    What happens if you run kmstest and any boot logs you can share?

    Hi Krunal,

    I tested the command kmstest and I had this error:

    root@am335x-evm:~# kmstest
Could not get DRM master permission. Card already in use

    In the other commands, I have this result. For size, the settings still use the default LCD for EVM kit.

    Hi,

    It seems like weston is running, can you try to disable weston? Next, try running kmsprint again.

    Hi Krunal, 

    Now if I executed the command kmsprint, I have this error:

    Hi,

    What's the purpose of the ST7789Vi driver? Also, could you share your boot log for further investigation?

    Regards,

    Krunal

    Hi, 

    Do I not need a driver?

    I attach the boot log.

    Hi,

    The display driver is called lcdc and Ido you have that enabled?

    Hi, 

    Yes, I use the default am335x-evm.dts and only edit the lcd and backlight configuration. 

    Thanks,

    Hi,

    What I mean is did you enable DRM_TILCDC in the Kernel config? That's the main display driver to use and not ST7789Vi.

    Hi,

    I checked the .config file of the kernel and yes I have DRM_TILCDC activated and the ST7789Vi driver is not activated because the driver is in Stating Drivers and I didn't enable this config now. 

    CONFIG_DRM_TILCDC=y
CONFIG_DRM_PANEL=y
CONFIG_DRM_PANEL_SIMPLE=y
#CONFIG_STAGING is not set

    I made some change in panel-simple.c and device tree because. I started the configuration using RGB888, but the panel I will use only has 16 Pins when RGB888 needs 24 Pins. For these, I change the panel-simple.c to work in RGB565:

    static const struct drm_display_mode newhaven_nhd_43_480272ef_atxl_mode = {
        .clock = 9000,
        .hdisplay = 480,
        .hsync_start = 480 + 2,
        .hsync_end = 480 + 2 + 41,
        .htotal = 480 + 2 + 41 + 2,
        .vdisplay = 272,
        .vsync_start = 272 + 2,
        .vsync_end = 272 + 2 + 10,
        .vtotal = 272 + 2 + 10 + 2,
        .flags = DRM_MODE_FLAG_NVSYNC | DRM_MODE_FLAG_NHSYNC,
};

static const struct panel_desc newhaven_nhd_43_480272ef_atxl = {
        .modes = &newhaven_nhd_43_480272ef_atxl_mode,
        .num_modes = 1,
        .bpc = 8,
        .size = {
                .width = 95,
                .height = 54,
        },
        .bus_format = MEDIA_BUS_FMT_RGB888_1X24,
        .bus_flags = DRM_BUS_FLAG_DE_HIGH | DRM_BUS_FLAG_PIXDATA_DRIVE_POSEDGE |
                     DRM_BUS_FLAG_SYNC_DRIVE_POSEDGE,
        .connector_type = DRM_MODE_CONNECTOR_DPI,
};

    and the device tree to

            panel {
                compatible = "newhaven_nhd_24_240320cf_csxn_f";

                pinctrl-names = "default", "sleep";
                pinctrl-0 = <&lcd_pins_default>;
                pinctrl-1 = <&lcd_pins_sleep>;
                backlight = <&lcd_bl>;

                port {
                        panel_0: endpoint@0 {
                                remote-endpoint = <&lcdc_0>;
                        };
                };
        };

    But I keep having some wrong settings why I keep seeing nothing on the screen.

    Hi,

    In the panel-simple, I still see the bus format as RGB888 so did you change that to RTB565? Also, could you add printk statements in the following: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/drivers/gpu/drm/tilcdc/tilcdc_drv.c?h=ti-linux-5.10.y#n169. I don't see any lcdc prints in your boot logs so not sure if something is not configured.

    Hi Krunal, 

    Thank you very much for your reply.

    Sorry, I copied another code instead of the code with the change to RGB565. The correct code is:

    static const struct drm_display_mode newhaven_nhd_24_240320cf_csxn_f_mode = {
    .clock = 6000, // Adjust based on your display's datasheet
    .hdisplay = 240,
    .hsync_start = 240 + 2,
    .hsync_end = 240 + 2 + 20,
    .htotal = 240 + 2 + 20 + 2,
    .vdisplay = 320,
    .vsync_start = 320 + 2,
    .vsync_end = 320 + 2 + 10,
    .vtotal = 320 + 2 + 10 + 2,
    .flags = DRM_MODE_FLAG_NVSYNC | DRM_MODE_FLAG_NHSYNC,
};

static const struct panel_desc newhaven_nhd_24_240320cf_csxn_f = {
    .modes = &newhaven_nhd_24_240320cf_csxn_f_mode,
    .num_modes = 1,
    .bpc = 8,
    .size = {
        .width = 36, // Adjust based on the physical dimensions of your display
        .height = 48,
    },
    .bus_format = MEDIA_BUS_FMT_RGB565_1X16,
    .bus_flags = DRM_BUS_FLAG_DE_HIGH | DRM_BUS_FLAG_PIXDATA_DRIVE_POSEDGE | DRM_BUS_FLAG_SYNC_DRIVE_POSEDGE,
    .connector_type = DRM_MODE_CONNECTOR_DPI,
};

    I've debugged the tilcdc_drv.c file and the execution hangs on the following line.https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/drivers/gpu/drm/tilcdc/tilcdc_drv.c?h=ti-linux-5.10.y#n317

    What could be the reason for it to fail at this point?

    Thanks, 

    Xavier

    Hi Xavier,

    Just to confirm, in the panel-simple file you added the two functions but did you also define an entry here: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/drivers/gpu/drm/panel/panel-simple.c?h=ti-linux-5.10.y#n3994.

    Hi Kurnal, 

    The lines you mention were already added because without them the Kernel would not compile.

    	}, {
		.compatible = "newhaven,nhd-2.4-240320cf-csxn-f",
		.data = &newhaven_nhd_24_240320cf_csxn_f,
	}, {

    Today, I did new tests, I copied the settings I had for the nhd_24_240320cf_csxn_f panel to the nhd_43_480272ef_atxl panel in panel-simple.c. I have compiled the Kernel and modified the device tree to use the
    compatible = "newhaven,nhd-4.3-480272ef-atxl";
    is place of
    compatible = "newhaven,nhd-2.4-240320cd-csxn-f";

    After that, I executed de modetest and I saw the correct screen dimensions for nhd-4.3.

    Maybe the nhd_24_240320cf_csxn_f should be declared somewhere else?

    Thanks,

    Hi,

    Thanks for the update and that's strange how changing name worked. Did you try to grep that compatible field in Kernel to see if anyone else is using it?
