Hi, I doubt you will be able to get this to work since u-boot knows nothing about the frame buffer. You can put an image into the kernel (using some magic juju - don't know/don't ask), however making this image work with multiple resolution displays is going to be a challenge. If you do your best to speed up the kernel boot time (e.g. quiet & ip=off kernel arguments) you can get a ramdisk loaded pretty quickly. You can also reduce the 3 seconds u-boot waits for a keypress as well. In the ramdisk you can then use 'psplash' or other program to load a screen image. Before I found 'psplash', I simply did a 'zcat' on a ntsc sized image into the frame buffer. Once that is done you can pivot-root+chroot to the FLASH filesystem and continue to boot as normal. I managed to get the kernel + ramdisk image to fit into the kernel partition on the DM355. 'psplash' has the advantage that it will find the display resolution at run time but you are limited to a graphic over a plain coloured background - it works as long as the graphic fits on the smallest display size you intend to use. This is useful as you then do not need to have special kernels or ramdisks for each screen resolution. Of course if you only have a single sized display then this isn't a great advantage. You do get a 'free' progress bar though ;-) Regards Phil Q Phil Quiney, Senior Software Engineer Trinity Convergence Cambridge Business Park Cowley Road Cambridge CB4 0WZ, UK T: +44(0)1223-435536 F: +44(0)1223-435560 www.trinityconvergence.com <http://www.trinityconvergence.com/>

I am looking for logo display during u-boot time bootup and before kernel gets uncompressed. Is there any provision in uboot to display logo during bootup and do system initialization at background?
