Linux/PROCESSOR-SDK-AM335X: u-boot splash screen for am335x starter kit and beagle bone black with display 4d cape 43t LCD

Govindaraji Sivanantham

Tool/software: Linux

Hello TI,

I need to know, how to bring up the u-boot splash screen in u-boot 2016.05 revision . Please help me add the splash screen to u-boot. I am using am335x starter kit and beagle bone black with display 4d cape 43t lcd.

Hello Govindaraji,

You can use this post as reference.

Hi Kemal,

I followed the procedure. It is not working with that LCD driver and with changes in u-boot 2016.05
and even the changes with u-boot Image not booting the Linux kernel also.

Can you try with u-boot-2014.7?

Hi Kemal,

I switched to git u-boot branch ti-u-boot-2014.07. And there is no config files in it for the AM335x Starter Kit u-boot configuration.

Try:
git clone git://git.ti.com/ti-u-boot/ti-u-boot.git
git checkout v2014.07

Hi Kemal,

I couldn't find the u-boot config file for am335x boards from u-boot git revision v2014.07. I can see configs folder only from v2015.04 git revision.

The configs directory was introduced later, there is no configs directory in earlier versions.

Hi Kemal,

U-boot splash Screen is working with u-boot source code(v2016.05) and with AM335x SK board.

Starter ware examples/evmskAM335x/raster/ code reused for this demonstration (AM335X_StarterWare_02_00_01_01)

below line added to the u-boot top level Makefile

+libs-y += drivers/lcd/

below lines added to the u-boot top board/ti/am335x/board.c

+#include <rasterDisplay.h>

add below line to board_init() function of board/ti/am335x/board.c

+#ifndef CONFIG_SPL_BUILD
+ Lcd_Init();//Initialize
+#endif

But when using this u-boot , kernel boot stops after below message

[    1.066692] [drm] Initialized drm 1.1.0 20060810
[    1.074126] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
[    1.080903] [drm] No driver support for vblank timestamp query.

Guide me how to solve this problem

and i also wanted to know the license compatible when i use the starter ware code in u-boot?

last question is after adding the lcd driver support and splash screen, u-boot image size becomes double(1.2MB). due this u-boot delays to load the kernel? and Is there any way to reduce the final u-boot binary size?

Hi Kemal,

After Adding the raster display code into u-boot, splash screen displays at the u-boot stage but kernel loading stops during drm driver initialization

below one is kernel boot log

Please, check this link for some possible causes, likewise display timing, size or other configuration parameters may cause such lost sync.

Hi Kemal,

In that link, Add the Linux kernel configuration “CONFIG_FB_PRE_INIT_FB” to reuse the framebuffer contents that was set up by the U-Boot. but that option not able to enable it in TISDK Linux kernel version 4.4.32.
Even we tried with changing display timing parameters in u-boot( with rasterDisplay), But still the errors occurred while insmod tilcdc driver in Linux kernel.

After insmod of tilcdc module the tty service(minicom) gets inactive. above dmesg are taken from ssh

Please help us solve the issues

I tried this lists.freedesktop.org/.../104415.html patch to recover the sync lost error in Linux kernel version 4.4.32. But no improvement.

Does the board successfully boot until login prompt? Can you switch to the latest U-Boot?

yes the board boots successful, but the tty service(minicom) gets inactive while inserting tilcdc driver. tried with u-boot version 2016.05, 2017.01.

Hello Steve,

Any update, regarding Sync lost error in Linux kernel (4.4.32) when using the AM335X_StarterWare_02_00_01_01 raster display code in u-boot (2016.05) for a splash screen.

I don't get any Sync lost errors if the generated image.h match the display timings in rasterDisplay.c

/* Configuring horizontal timing parameter */
RasterHparamConfig(SOC_LCDC_0_REGS, 480, 4, 8, 43);

/* Configuring vertical timing parameters */
RasterVparamConfig(SOC_LCDC_0_REGS, 272, 10, 4, 12);

i am using same configuration for display timing, I used below lines to generate the image.h file and i am getting sync lost error.

bmpToRaster 480 272 image.bmp ./image.h 24 RGB

but this image.h file how to match with the rasterDisplay.c display timings .

Can you check on your Starter Kit, whether you will get these errors with the attached u-boot.img?

2273.splash.tar.gzCan you use the framebuffer driver already in u-boot. It is in drivers/am335x-fb.c. I've been tasked with coming up with splash screen code and I have it working on the AM335x StarterKit on either 3.2 or 3.3 SDK. I have attached the patches. The LCD data is hard coded for Starter Kit. Currently I'm updating the code to SDK 4.0 and are starting to use the LCD data from the dtb. The image is a gzipped bmp file that is RGB565 and is the size of the screen.

Hi Steve,

Thank you for your support,

Starter kit shows splash logo on LCD with the patch and tilcdc sync lost not occurred

Since am335x_evm_splash_defconfig gives the compilation error with the patch i did one below changes in configs/am335x_evm_defconfig

+CONFIG_SYS_EXTRA_OPTIONS="NAND,SPLASH"

but blue and red colors are interchanged.
to resolve the this we should use below line in dts file
blue-and-red-wiring = "crossed";

To use the custom lcd with the beagle bone black please guide me, to change the values of display timing and panel-info.

and i am not clear on below dts parameter in board.c

+ pnltmp.pxl_clk_div = 2;

+ pnltmp.pup_delay = 1;
+ pnltmp.pon_delay = 1;
+ panel_info.vl_rot = 0;

+ .vl_bpix = 4,
+ .priv = 0

In future we are planning to use 24 bit image RGB888. is that possible to have 24 bit u-boot splash logo?

Hi Steve,

Please update the u-boot frame-buffer driver patch to use the LCD data from DTB for the u-boot splash screen.
