[U-Boot-Users] Ramdisk too big, CRC problem

[Sonia Martinez]

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 to 5.6 MB a CRC problem
appears.

Here is the log:

## Booting image at 00340000 ...

   Load Address: 00000000

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
