Dear Leif,

Can some body throw a light to increase the RAMDISK size.
There is a hard limitation in u-boot, causing "bootm" command to silently fail gunzip with images having an uncompressed size of > 4Mb.
This has NOTHING to do with ramdisk sizes.
U-Boot does not uncompress ramdisk images, this is done by the Linux kernel. U-Boot just (loads and) passes the address of the ramdisk image to the Linux kernel without touching the data at all.
The ugly fix would be to just increase this value (like I did).
No such change is needed (unless you end up with a Linux kernel that does not fit in 4 MB any more).
Best regards,
Wolfgang Denk
