This is where I ran into problems. When I run the "ext2load usb 1:1"
command, I get an error message:
Marvell>> ext2load usb 1:1 0x02000000 uImage
** Bad partition 1 **
What's the output you get from "usb start" ? Should be someting like
Marvell>> usb start
(Re)start USB...

Does it see your sd card as device 1? i.e.
Marvell>> usb storage
Device 0: Vendor: Generic Rev: 9451 Prod: STORAGE DEVICE
Type: Removable Hard Disk
Capacity: not available
Device 1: Vendor: Generic Rev: 9451 Prod: STORAGE DEVICE
Type: Removable Hard Disk
Capacity: 15407.0 MB = 15.0 GB (31553536 x 512)
And does u-boot see the partitions?
Marvell>> usb part 1
print_part of 1
Partition Map for USB device 1 -- Partition Type: DOS
Partition Start Sector Num Sectors Type
1 1953 1000001 83
2 1001954 1000000 83
3 2001954 12695312 83

Any idea why I'd be getting a "bad partition" message?
Here's the
output of parted on the SD card:
[root@hockey ISO]# parted /dev/sdb print
Model: USB Mass Storage Device (scsi)
Disk /dev/sdb: 15.7GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
1 1000kB 513MB 512MB primary ext3 boot
2 513MB 1025MB 512MB primary linux-swap(v1)
3 1025MB 15.7GB 14.7GB primary ext4
I'll continue to fiddle with this again today.
