Ramdisk too big, CRC problem

Hi to all,

I've been working without problems booting linux from RAM with uboot using this command:

bootm 340000 480000

My system has 32MB of RAM memory.

Linux image is bzip2 compressed occupying 1.2 MB. It's loaded in 0x00000000.

Ramdisk image is uncompressed, and with size up to 4MB there is no problem in booting the whole system, but if it grows up to 5.6 MB a CRC problem appears.

Here is the log (I've added some prints):

## Booting image at 00340000 ...

It seems that the ramdisk image is corrupted because of the initialization of linux image. Can anyone help me? Is it something related to the descompression of bzip2 image?

Best regards,

Sonia
