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

Please give your suggestion and solution ASAP.
Note: I am trying to display from SD-card.
Thanks & Regards,

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
