Re: [Gumstix-users] FYI recovering from boot delay=0

[Patrick M. (D. - CA/Ottawa) <Pat...@dr...>]

The only problem with this method is that the environment has a checksum or CRC associated with it, so changing that will invalidate the environment and cause u-boot to use defaults.  Hopefully the defaults are appropriate for your purporses.

Subject: [Gumstix-users] FYI recovering from boot delay=0


FYI,

You can reset the u-boot bootdelay from 0 if you can get to a linux prompt.

dd if=/dev/mtd2 of=env.blob
vi env.blob
Find the string bootdelay=0 and replace the 0 with a 5
dd if=env.blob of=/dev/mtd2

The other way to do it is to create a boot.scr, add it to your mmc boot partition, and add a
setenv bootdelay 5
saveenv

To the top of that script.   For more details see http://wiki.gumstix.org/index.php?title=U-Boot
