Re: Problem in loading JFFS2 file system on Strong ARM sa1110/1111 targetboard







          We are using following hardware and software patches as shown
below.
Processor: Intel StrongARM-1110
Architecture: Intel-Assabet
Companion chip: SA 1111
Linux version 2.4.17-rmk5
Using  redboot bootloader
                    We have made zimage by enabling Jffs2 filesystem and
MTD option  in configaration file.I can able download kernel  and JFFS2
filesystem successfully by following redboot procedure but unable to see
JFFS2's  Memory address or flash address or length entry point as shown by
redboot procedure by using "fis list" commond . and at the neponset console
i got these messages as shown below......please help me in this regard.
               Thanx in advance
                Linux version 2.4.17-rmk5 (root@xxxxxxx.localdomain) (gcc
