It is a SODIMM board based on iMX25 and 2GB of Flash memory

Yes, of course :-)

So instead of:

RedBoot> fis create -b 0x82000000 -r 0x82000000 -l 0x04000000 -s 0 -f 0x01f40000 storage

i need to type:

RedBoot> fis create -b 0x82000000 -r 0x82000000 -l 0x40000000 -s 0 -f 0x01f40000 storage

I guess i should have problems with the locations of the RedBoot config & FIS directory partitions ...
Maybe I could choose a different range of Flash addresses:

RedBoot> fis create -b 0x82000000 -r 0x82000000 -l 0x04000000 -s 0 -f 0x10000000 storage
