How does one change the kernel that uboot loads from mtdflash and
instead boots a kernel from an ext filesystem on an attached (uboot
supported) usb flash drive? Furthermore, is there a way to get uboot
to also load an initial ram file (disk or fs)? The hardware in
question is a guru plug and I've got the jtag and console adapter.
Thanks in advance,
Matt
on a guruplug you need to edit the values stored in nvram you can do it
two ways, 1) interupting the boot process and using printenv setenv
editenv saveenv to get set and save the variables.
there is a utility in uboot-tools that should let you edit it from the
running system
