Why are you using 0xA5000000 address here as the frame buffer base address?
Yeah this is a very much a valid frame buffer address. I 'used' to use this for splash screen also and it worked fine.
Can you see changes on the display if you write data to this address by U-Boot "mw" command (i.e. "mw a5000000 ffffffff 100") ?
No.. but the memory will have all "f"'s contained in it until I reboot.
Well, if you do not see changes on the display, that means your OMAP display controller doesn't fetch data starting from this frame buffer base address. Otherwise you would see some white lines on the display.
Best regards,
