hi I've some trouble with redboot on a ixp435 custom board.
following works

    > load -r -b 0x01600000 zImage
    > exec
        Using base address 0x01600000 and length 0x00104b4c

Then I created zImage partitions successfully with zImage successfully.

    zimage            0x50080000  0x50080000  0x00120000  0x01600000
    FIS directory     0x50FE0000  0x50FE0000  0x0001F000  0x00000000
    RedBoot config    0x50FFF000  0x50FFF000  0x00001000  0x00000000

But following doesn't work, I don't know why.
    > fis load -b 0x01600000 zimage
    > exec 0x01600000
        Can't execute Linux - invalid entry address

I've found that crc error caused the problem.
    RedBoot> fis load -b 0x01600000 zimage
    ** Warning - checksum failure.  stored: 0xfe06c871, computed: 0x151a32bf
    RedBoot> 
So I turned off CRC_CHECK and rebuilt redboot & upgraded RedBoot.
But I faced another problem. I couldn't erase flash memory. 
Now I can't even upgrade Redboot anymore.

'checksum failure' means that the flash image is corrupt, or that the 
crc has become corrupt.
Because 'fis load zimage; exec' does not work I would think the flash 
image is corrupt.
So there is no problem with 'fis load' or with 'exec' or with the 
'CRC_CHECK', only a problem with your flash.
I would only turn off CRC_CHECK if the cpu would not be fast enough to 
do the crc..
This reply comes late (just back from holidays), maybe you have already 
solved your flash problems?
(take another board and start from scratch with an empty flash)
Anyhow, regards,
Jürgen
