Openwrt on Dockstar : new defaut environment variables

Hi,
on my second Dockstar, i put the new Uboot (2015.10) and i would like to put Openwrt; Unfortunately, it starts searching a kernel image on usb device . i would like put OW on nand of dockstar, not on usb.
I suppose due to env variable (bootcmd). And so, i would like change this default variable to realize this installation :
https://wiki.openwrt.org/doc/howto/dockstar_sandbox
Is it possible ? and How ?
Thanks a lot

My environnement :

Ré,

It is certainly possible. I'm on the road right now so I am not sure I have the u-boot env set to post. I'll see of I can find it.

Basically, the envs need to be the same as Jeff orginal u-boot installation. So if you keep the log when you install that u-boot, those can be used to boot openWRT.

Re,

I'll post instruction so you can try before commiting them to Nand.

Ré,

If you have run the openWrt installation per instruction on that page before installing new u-boot, then try this.

Power up, stop serial console and set these 2 envs one by one with setenv.

setenv pogo_bootcmd 'if fsload uboot-original-mtd0.kwb; then go 0x800200; fi'
setenv bootcmd 'run pogo_bootcmd; reset'

And then

boot

Pls post the entire serial console log here.

This might not work right away but I would like to see the behavior.

Ré,

This is more likely to work.

Power up, stop serial console and set these envs one by one with setenv, and then boot

setenv rescue_bootcmd 'if test $rescue_installed -eq 1; then run rescue_set_bootargs; nand read.e 0x800000 0x100000 0x400000; bootm 0x800000; else run pogo_bootcmd; fi'
setenv rescue_set_bootargs 'setenv bootargs console=$console ubi.mtd=2 root=/dev/mtdblock2 ro rootfstype=jffs2 $mtdparts $rescue_custom_params'
setenv rescue_installed 1
setenv bootcmd 'run rescue_bootcmd; reset'
boot
