Altered Uboot env, PPV4, need to revert to initial env

Hi, with the help of bodhi and shv, I was able to get my pogoplug series 4 to flash the custom uboot. I was unable to boot with a second usb drive plugged in and attempted to change some of the usb_boot env and usb_root settings in uboot.

I was hoping that someone might be able to help identify what command I would need to revert my env back to normal. I've tried, but I don't think that I am chaining them together right. Every time I make a change, it seems to get worse.

Follows is my printenv listing.

rootdelay rootfstype=$usb_rootfstype $mtdparts $usb_custom_params

In response to my own question, I proceeded as if I hadn't updated the uboot. I booted into debian, placed the flashing tools and kwb file in my tmp directory and went through the initial setup.

Maybe not the cleanest, but it erased the mistakes I made.

Just need to do a little more research into uboot I think.

@t3ch42,

Thanks! That worked. Now to get the other hard drives to boot in order and consistently and I'll be happy.

Will do more research into that aspect as well.

Thanks again,
