force Debian to Boot first from USB Flash not HDD

Dears
i have Pogoplug E02 works with Debian using USB Flash Stick and i use my USB HDD to access it.
but when i make a reboot for the device it stop working , after serial connection i found that it detect the HDD first and trying to boot using it but it failed and ignore the stick , i want to force the device to boot from the USB flash even there are other USB Storage devices connected to.

any idea.

do you have any idea??

msanad,

You still have the same boot command:

bootcmd=usb start; run usb_bootcmd; usb stop; reset
usb_bootcmd=run usb_set_bootargs; run usb_boot
usb_set_bootargs=setenv bootargs console=$console root=/dev/sda1 rootdelay=10 rootfstype=ext3 $mtdparts
usb_boot=mw 0x800000 0 1; ext2load usb $usb_device 0x800000 /boot/uImage; if ext2load usb $usb_device 0x1100000 /boot/uInitrd; then bootm 0x800000 0x1100000; else bootm 0x800000; fi

Arrange them backward in this fashion, and set up your new u-boot envs sequence in a notepad. After you proof-read it, cut and paste to the console prompt.

sorry ,
but i dont undersatand what do you mean by (Arrange them backward in this fashion )

msanad,

Just mean when you are troubleshooting problem with u-boot envs, it is best to list them in the reversed execution order, starting from bootcmd. So if you do that, you'll see the mistake is:

bootcmd=usb start; run usb_bootcmd; usb stop; reset

It should be

bootcmd=usb start; run bootcmd_usb; usb stop; reset
