Dear all,

I w= ould ask a question as barebox user.

I mind to set a variable as result of memory readin= g but I understand it doesn’t implemented redirection.

I’d like to do somethi= ng of this:

myvar=3D&= #8221;”

= memcpy –s /dev/nor0.switch –d $myvar 0x0 0x0 4=

=

or

myvar=3D”$(cat /dev/nor0.switch)”

I think, I use one of l= ast releases (version command?).

Thanks to everyone can help me.

Marty

If I understand correctly then you want to copy the content of /dev/nor0.switch to a variable. I'm afraid there currently is no way to do this in barebox. What information is inside this nor partition? It seems like you want to implement some kind of redundant boot and want to decide which rootfs you want to boot. Am I right?

You can access the barebox environment from Linux using scripts/bareboxenv (I have a patch which compiles it for the target also) We use this in a similar setup to set a variable under Linux and read it out under barebox to decide which rootfs to boot. If you prefer to put this into a seperate partition you can add it using saveenv and loadenv .
