Setting up Multi-boot (SD/USB vs. NAND)

[philipl]

Hi all,

I spent some time today getting a multi-boot configuration going on my plug - if I have an SD inserted when I boot, it will use the card, otherwise it falls back to NAND - all without manual intervention. There's no real magic involved but it's worth documenting, so I've added a wiki page for it:

Can you write the commands to set the vars? I'm getting strange errors when trying to set them.
TIA

You probably need to do:

Code:

setenv varName 'value'

Could you post the "USB Variables" in the same format as the "SD variables"?
Thanks,
Ian

I've added a USB example section.

Thank you very much for the quick response. I think $(bootargs_sd) should be $(bootargs_usb) in bootcmd_usb.

A newbie here - The part I am stuck is essentially the information leading up to this. Is there an image we can use to format our memory card for use? Windows/Linux pointers to  get that done?

That will get the rootfs on the card. Then it's a simple matter to copy the kernel over and then use SD boot as per the instructions.
