>Is there some way to dual-boot a ts7xx0 board?
I have been using multiple configurations on a ts-7260 with no real
problems.
My default configuration is to load a kernel named 'mk' from the on-board
flash, using a USB memory stick for the root filesystem. To get this
configuration, I turn the power on and let it boot.
To get one of the other configurations, I type control-c at the serial
console right after power on. This gets me a redboot prompt, where I
can explicitly load other kernels. The original kernel shipped with the
board is still present in the on-board flash under the name 'vmlinux'.
I also sometimes load a test kernel over HTTP.
( I posted detailed commands for multiple kernels in flash under
the subject "Install a kernel in a TS-7400" a few days ago. )
b.t.w. I notice that usual discussions about booting with redboot usually
involve a command that looks like
exec -c "bunch of long options here"
It should not be a big deal to hack up your kernel to have an option
string compiled in. In that case, you could shorten the command to
just "exec", so your multi-boot command could be as simple as
fis load kernelname
exec
for example. I'll conceed that the linux kernel is pretty twisted in
some places, and it may be difficult to find exactly _where_ to insert
your own parameter string. :) Of course, once you can insert a specific
parameter string, you could have the kernel select on of many strings
based on jumpers.
Is that something like what you had in mind?
