Customizing the splash screen[edit | edit source]
Instructions[edit | edit source]
The following U-Boot environment variables are required:
splashimage: RAM address where the BMP image is loaded. Please note that it must be a 32-bit (eg:0xc4100000)splashfile: image name to load and then display at boot. (eg:splash_landscape.bmp)
uSD Splash image[edit | edit source]
U-Boot variables[edit | edit source]
splashimage=0xc4100000 splashfile=splash_landscape.bmp
Commands update splah image on u-boot via tftp[edit | edit source]
If you want to upload the image via tftp you must first format the ext4 partitions of the uSD without the metadata_csum flag (eg: mkfs.ext4 -O ^metadata_csum -F -L <name> <partition>)
The following commands are used to store in uSD flash a BMP image loaded via tftp(e.g. the image are con /tftp/desk-mp1-l/splash_image.bmp, serverip=192.168.0.13)
tftp ${loadaddr} desk-mp1-l/splash_image.bmp
ext4write mmc 0:8 ${loadaddr} /splash_landscape.bmp ${filesize}
Not using the metadata_csum flag is not recommended!
Commands update splah image with host[edit | edit source]
You can update the splash image with the following steps:
- connect the uSD to the host
- mount the boot partition (eg:
sudo mount /dev/sdb8 /mnt) - copy on
/mntpartition the image with this name:splash_landscape.bmp - umount the uSD and excecute the boot
Commands update splah image on userspace[edit | edit source]
After booting and into userspace, get the image to have as splash, for example using a scp command from the host, the boot partition should already be mounted in /boot, put the image to use in the partition, the image must have the name splash_landscape.bmp.
