This is what I observed: 1) I loaded a Linux kernel into RAM at 0x200000 on a 405 system. I loaded an initial ramdisk images into RAM at address 0x300000. Now 'bootm 200000 300000' boots my system correctly. 2) Same loading as above. But I made the kernel image CRC check fail (mw 220000 12345678). I get: ... Verifying Checksum ... Bad Data CRC ERROR: can't get kernel image! => That's ok. 3) Same loading as above. But I make the ramdisk CRC check fail (mw 320000 12345678). I get: ## Booting kernel from Legacy Image at 00200000 ... ... ## Loading init Ramdisk from Legacy Image at 00300000 ... ... Verifying Checksum ... Bad Data CRC U-Boot 1.3.2-00450-g77dd47f (Apr 21 2008 - 14:43:23) Hmm, I expected the same behavior as for a corrupted kernel image. So what should be the correct behavior? I would like to get back to the prompt on any CRC error. So is this a bug? Matthias
