iTOP-3399 development board Linux system modify the boot LOGO

The boot logo of the ITOP-3399 platform is divided into two stages, the logo of the u-boot stage and the logo of the kernel stage. If the two use the same logo image, they can be seamlessly connected. If you need to change the boot logo, you only need to replace kernel/logo.bmp and kernel/logo_kernel.bmp, as shown in the figure below:

logo.bmp is the logo when Uboot is started. logo_kernel.bmp is the Logo when the Kernel is started. Make a boot logo and find a picture with a resolution of 1280*800. Because the author uses a seven-inch LVDS screen for testing, so choose the resolution of the seven-inch LVDS screen. The resolution can be set according to the screen parameters. Open the Photoshop software, set the size of the picture in the PS software, and save it as a picture in bmp format. The author uses the following pictures as uboot logo and kernel logo respectively:

Replace the pictures just made with the following files in the linux source code: kernel/logo.bmp and kernel/logo.bmp. Recompile the kernel and burn the generated kernel.img into the board.
After flashing into the image, as shown in the figure below, you can see that the uboot startup logo and the kernel startup logo have been replaced.
