Comment(by werner):
So you want a means to replace the splash screen image on the devices in
the
field ? For this, you need to convert the PNG file to a compressed raw
frame
buffer content and then flash this into the splash screen partition.
For the conversion, go to svn.openmoko.org/trunk/src/host/splash/ and run
./splashimg.pl boot_image.png | gzip -9 >new_splash.gz
If your update process runs under Linux (OE package ?) you'd then execute
the following commands:
flash_eraseall /dev/mtd4
nandwrite -p /dev/mtd4 new_splash.gz
If you update through DFU, you would:
dfu-util -a splash -R -D new_splash.gz
Note that there's also a copy of the image in the package the factory
uses.
You'll want to change that one as well.
Note the NOR also contains a copy of the splash screen. If you generate a
new NOR image with "mknor", just specify the new image with -s
boot_image.png,
and it will put the "openmoko" text near the bottom of the screen.
