Late response on this one: You don't have to restart. Instead, you can just overwrite it on the command line and boot afterwards: barebox: global.linux.bootargs.base=console=ttymytempconsole0,115200 barebox: boot Some more background: The idea is that the bootentries in /env/boot/* can be executed and setup the boot environment, afterwards you would only run 'bootm' without additional arguments. For example you could execute /env/boot/nand-ubi, then your setup would be: bootm.image = /dev/nand0.kernel.bb bootm.oftree = bootm.initrd = linux.bootargs.base = console=ttymxc0,115200 linux.bootargs.ip = ip=dhcp linux.bootargs.root = root=ubi0:root ubi.mtd=nand0.root rootfstype=ubifs linux.mtdparts.nand0 = mxc_nand:512k(nand0.barebox)ro,128k(nand0.bareboxenv),4M(nand0.kernel),-(nand0.root) linux.mtdparts.nor0 = physmap-flash.0:512k(nor0.barebox)ro,128k(nor0.bareboxenv),4M(nor0.kernel),-(nor0.root) If then you want to boot once with a devicetree without permanently changing you environment, you could do a barebox: global.bootm.oftree=/whatever/oftree barebox: bootm The possibilities are there, maybe the question is how we can simplify (and document) them so that people are actually aware of what can be done.
