I've attempted to increase the uboot bootdelay value higher than the 3 that is default, however after doing the setenv/saveenv/reset, the printenv still reports the 3 seconds value. Is the bootdelay value write protected in the uboot image? I'm using the patched uboot, version "3.4.27 - pingtoo patch.01".

It apparently "yes" it is hard code some where Grin I tried in my custom file when use with sheeva-installer, it did not change either. I have not spend time to debug the u-boot code on this issue because seems to be less important since nobody ask this before Cheesy I will have a look at it, may be included in my next patch?

That'd be great. All the other reading and experience I've had with uboot has had ethaddr, serial etc. flagged as being set-once only, but I changed ethaddr multiple times without problem, so I figured no environment variables were protected.
