Hi All
Is anybody had used "load " command with
xymodem on redboot .
I had used like this
RedBoot> load -r -b 0x8c080000 -m xmodem
but its not working.
Please suggest me to overcome with this problem.
I am stuck hear since my target dosen't have ethernet connectivity and
my PCI card doesn't supporting the flash which we had used.
Thanx

Dear Nick
Thanks for your direction.But I had used load with -r option,
RAM add : 0x8c080000
Below is the detail ,might give some clue.
RedBoot> dump -b 0x8c080000
8C080000: 00 04 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
8C080010: 00 00 44 00 00 00 00 00 00 00 00 00 00 00 00 00 |..D.............|
RedBoot> load -r -b 0x8c080000 -m xmodem
CCCCCCCCCCCCCCCCCCCCCRaw file loaded 0x8c080000-0x8c07ffff, assumed entry at 0x8
