Hello Jens,

Thanks for your quick response.

Actually I tried with U-Boot latest release (u-boot-2013.01.01.tar.bz2) also.But I am not able to see the SPLASH SCREEN. So, please share the SPLASH SCREEN image enable procedure for latest U-boot (u-boot-2013.01.01.tar.bz2) source code for i.mx53loco.

Thanks & Regards, Nandakumar R.

Hello,

I would like to enable & view the splash screen in U-Boot source (u-boot-2009.08.tar..gz) code.

Please help me to come-out from this task.

Please read the U-Boot documentation http://www.denx.de/wiki/DULG/UBootSplashScreen

btw u-boot 2009.08 is very old. it#s recommend to use the current release.

Regards

Jens

U-Boot release 2013.01.01 for mx53loco supports two LCD panels, CLAA07LC0ACW and Seiko-43WVF1G. If you have a different panel, you will have to add support for it. If you have Seiko panel, please set up environment variable panel as follows:

=> setenv panel seiko => saveenv

and reboot, then use load a bmp file and use "bmp" command to display it.

Thanks,

Anatolij

Hello,

1) Please share me, if any one used mx53loco - LVDS settings for hannstar (mcimx-lvds1) display as per the below,

setenv bootargs_base 'setenv bootargs console=ttymxc0,115200 console=tty1 video=mxcdi1fb:RGB666,TOSHIBA-XGA di1_primary ldb=single,di=1,ch1_map=SPWG'

2) And I have modified the below files and codes for splash screen support for mx53loco as per the mx6qsabrelite.c. Please correct me, if I wrong.

File Name: mx53loco.h

Included: #define CONFIG_SPLASH_SCREEN #define CONFIG_SPLASH_SCREEN_ALIGN #define CONFIG_SPLASH_SCREEN_LVDS #define CONFIG_CMD_BMP

File Name: mx53loco_video.c

Include: static struct fb_videomode const mcimx_lvds1 = { .name = "Hannstar-XGA", .refresh = 60, .xres = 1024, .yres = 768, .pixclock = 15385, .left_margin = 220, .right_margin = 40, .upper_margin = 21, .lower_margin = 7, .hsync_len = 60, .vsync_len = 10, .sync = 4, };

int board_video_skip(void) { int ret; char const *e = getenv("panel");

printf("Display Panel Name: %s\n", e);

if (e) { if (strcmp(e, "seiko") == 0) { ret = ipuv3_fb_init(&seiko_wvga, 0, IPU_PIX_FMT_RGB24); if (ret) printf("Seiko cannot be configured: %d\n", ret); return ret; } else if (strcmp(e, "Hannstar-XGA") == 0) { ret = ipuv3_fb_init(&mcimx_lvds1, 0, IPU_PIX_FMT_LVDS666); if (ret) printf("MCIMX_LVDS1 cannot be configured: %d\n", ret); return ret; } }

/* * 'panel' env variable not found or has different value than 'seiko' * Defaulting to claa lcd. */ ret = ipuv3_fb_init(&claa_wvga, 0, IPU_PIX_FMT_RGB565); if (ret) printf("CLAA cannot be configured: %d\n", ret); return ret; }

And I tried the below command. But not get the correct output (SPLASH Image) through U-Boot.

MX53LOCO U-Boot > tftp 100000 /tftpboot/lvds.bmp Using FEC device TFTP from server 192.168.1.176; our IP address is 192.168.1.189 Filename '/tftpboot/lvds.bmp'. Load address: 0x100000 Loading: T T T T T

Please give your suggestion and solution ASAP.

This is already part of include/configs/mx53loco.h

Please post your changes in the format of a patch so that we can understand exactly what you are changing.

Also, please make sure that the backlight is turned on.

On my previous email the mx53ard code I pointed you to uses PWM to drive the backlight, you could simply use a GPIO instead.

Hello Anatolij,

I really impressed for your quick response. I will correct it as per your inputs.

Thank you,

Regards, Nandakumar R.

I've never used mx53loco board, also I never used a hannstar display. The proper support for it is missing in U-Boot.

Also please restrict the line length in the email text to max. 72 characters and do not top post. Thanks!

setenv bootargs_base 'setenv bootargs console=ttymxc0,115200 console=tty1 video=mxcdi1fb:RGB666,TOSHIBA-XGA di1_primary ldb=single,di=1,ch1_map=SPWG'

support for mx53loco as per the mx6qsabrelite.c. Please correct me, if I wrong.

Did you set "panel" environment variable to "Hannstar-XGA" and saved the environment ? You are adding a check for it in the board code, you also have to set this variable and save it to the environment, then you have to reset the board so the new setting will take effect.

File Name: mx53loco.h

Included: #define CONFIG_SPLASH_SCREEN #define CONFIG_SPLASH_SCREEN_ALIGN #define CONFIG_SPLASH_SCREEN_LVDS

Why do you add CONFIG_SPLASH_SCREEN_LVDS here ? This configuration option is not available anywhere, at least in mainline U-Boot code.

#define CONFIG_CMD_BMP

File Name: mx53loco_video.c

Include: static struct fb_videomode const mcimx_lvds1 = { .name = "Hannstar-XGA", .refresh = 60, .xres = 1024, .yres = 768, .pixclock = 15385, .left_margin = 220, .right_margin = 40, .upper_margin = 21, .lower_margin = 7, .hsync_len = 60, .vsync_len = 10, .sync = 4, };

int board_video_skip(void) { int ret; char const *e = getenv("panel");

printf("Display Panel Name: %s\n", e);

if (e) { if (strcmp(e, "seiko") == 0) { ret = ipuv3_fb_init(&seiko_wvga, 0, IPU_PIX_FMT_RGB24); if (ret) printf("Seiko cannot be configured: %d\n", ret); return ret; } else if (strcmp(e, "Hannstar-XGA") == 0) { ret = ipuv3_fb_init(&mcimx_lvds1, 0, IPU_PIX_FMT_LVDS666); if (ret) printf("MCIMX_LVDS1 cannot be configured: %d\n", ret); return ret; } }

/*

• Defaulting to claa lcd.

*/ ret = ipuv3_fb_init(&claa_wvga, 0, IPU_PIX_FMT_RGB565); if (ret) printf("CLAA cannot be configured: %d\n", ret); return ret; }

And I tried the below command. But not get the correct output (SPLASH Image) through U-Boot.

Your extensions are not enough, I'm afraid. You probably also have to configure the pin mux for LVDS interface, enable the backlight of the display, configure the backlight intensity, etc. I'm not familiar with mx53loco, I cannot guide you what is all needed to make video support over LVDS working. Please read the schematics of the board and mx53 manual and make sure you understand what is needed to configure LVDS interface and backlight properly. Then add appropriate code.

Please give your suggestion and solution ASAP.

Note: I am trying to display from SD-card.

Why are you trying to load the bmp file from network then? Do you have a working tftp server for this purpose?

If you have the bmp files on the SD-card, then you have to use appropriate commands to load files from the card, like "mmc rescan", "fatload mmc 0:0 <addr> <filename.bmp>" or similar. Only after the file has been successfully loaded to the address <addr>, you can use "bmp display <addr>" command.

Thanks,

Anatolij
