Hi,

ti will only show black screen if booting from HDMI or DPI panel. At the momemt, we do not have support for HDMI/DPI in Uboot. If you have LVDS connected, please refer to the following: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_02_01_09/exports/docs/linux/Foundational_Components/U-Boot/UG-Splash-Screen.html?highlight=splash

Hi Krunal,

In the reference you provided , how to add the source information for emmc boot .

To display image from a different source, add the source information in struct default_splash_locations, which is defined in board/ti/<platform>/evm.c. For example in board/ti/am62x/evm.c, by default OSPI and SD card are added as source as shown below :

static struct splash_location default_splash_locations[] = {
     {
             .name = "sf",
             .storage = SPLASH_STORAGE_SF,
             .flags = SPLASH_STORAGE_RAW,
             .offset = 0x700000,
     },
     {
             .name           = "mmc",
             .storage        = SPLASH_STORAGE_MMC,
             .flags          = SPLASH_STORAGE_FS,
             .devpart        = "1:1",
     },
};
Change splashsource variable to the name of source defined in above struct.

In above structure how to add the source information for emmc boot and where to keep the custome.bmp.gz image in case of emmc boot

Thanks ,

Abhijeet
