Hi,

Merry Christmas!

In the spirit of Christmas and today is my birthday Cheesy I present my uboot-env setup. see the code box below. I also attach a version that should work with sheeval-installaer.

Please Note a few things you might consider changes, from beginning to the "r4" line mostly are variable to later "run macro" so you can change it fit your need. I am not saying don't change anything below "r4" line just be careful.

To use these macro try,Tip: use key TAB to complete typing
Code:
Marvell>> run bootk_xxx_yyy #<- replace xxx with (usb|mmc) and yyy with (ext2|fat)

I hope it is very clear on how to use it but just in case, a quick summary for a few important variables,

kMemory loading address for linux kernel.
iMemory loading address for initrd/initramfs
storagepartdevice number for use with load command, it should always start with "0",  can append with ":[0-9]".
bootk_netUse dhcp and tftp to boot. you will need to setup your dhcp to at lease handout "next_server", "subnet-mask", "routers" and your plug IP address.
bootk_xxx_yyyBoot from device type xxx(usb|mmc) use file system type yyy(fat|ext2) take kernel name from ${k}
bootki_xxx_yyysame as above except it will also load/boot with initrd/initramfs from ${i}


Code:
setenv real_bootcmd run bootki_nand_ubi
setenv bootcmd echo run r1 to recover
setenv bootdelay 10
