Hello,
is in current U-Boot a lcd driver for the am335x integrated
LCD controller? If yes, also with Splash screen support?
Thanks!
bye,
Heiko

Hi Heiko,
perhaps you should take a look at the DA8XX driver. At least
under Linux this driver also handles the AM335x.
Splash screen support (meaning support of the splashimage variable)
might be a problem because it expects a direct mapped physical address
where the splash image is stored - typically some onboard nor flash. But
AM335x designs typically have MMC, NAND or SPI flash attached. So you
probably need some commands to load the spashscreen from a flash device
and then use the 'bmp' command to display it. This should work with all
video drivers.

Ah! Hmm... I found only one board, which uses this driver ...
But it is a good starting point I think!
Thanks!
