[Ram2]

Hi Team

Currently we are working on imx8qxp-mek custom board on harknott branch, currently when board-boots up , after u-boot we are able see penguin logo by default . but we need to custmoize it and add our required logo .
Could any one share the steps how to proceed in yocto how to add custom logo 


Thanks

Hi @Ram2 

You need use devtool modify u-boot-imx to uncompress source code to workspace, modify code and generate patch ,then add the patch to uboot-imx bb file.

For adding a new logo, you need put bmp file to tools/logo, the file name should be $(BOARD).bmp or $(VENDOR).bmp.

# Generic logo
ifeq ($(LOGO_BMP),)
LOGO_BMP= $(srctree)/$(src)/logos/denx.bmp

# Use board logo and fallback to vendor
ifneq ($(wildcard $(srctree)/$(src)/logos/$(BOARD).bmp),)
LOGO_BMP= $(srctree)/$(src)/logos/$(BOARD).bmp
else
ifneq ($(wildcard $(srctree)/$(src)/logos/$(VENDOR).bmp),)
LOGO_BMP= $(srctree)/$(src)/logos/$(VENDOR).bmp
endif
endif

 Then modify board/freescale/imx8qxp_mek/Kconfig, modify the SYS_VENDOR in this file, the name should be same as your bmp file's.

Hi @Ram2 

You can refer this yocto guide to patch uboot source code

Where I can find the tools folder.
