Is there finally a patch upstream that creates fixed numbers for MMC/SD block devices? When I see patches like this it's probably time to remind how barebox can handle bootloader spec ;) Put a file like this to /loader/entries/loader.conf: title Phytec-Monster-Linux version 4.6 options rootwait linux-appendroot true linux /boot/zImage devicetree /boot/imx6q-phytec-pflaxy.dtb Then you can boot the system with "boot mmc3.0", no further barebox configuration is needed. Set nv.boot to mmc3.0 if you always want to boot from there. The same can be done with nfsroot: Put the rootfs somewhere reachable via NFS and do: boot nfs://nfshost//path/to/rootfs (You'll need a "ip=dhcp" in the options in your loader.conf) You can also create multiple loader.conf files with different device trees, barebox will then pick the one which is compatible to the current board. The above also works with NAND/UBI. "boot nand0.root.ubi.root" will boot from the root volume on the ubi found on the root partition from the nand0 device. Again, no further barebox configuration and no manual ubiattach required. the root= and ubi.mtd= arguments to the kernel will be automatically generated. Configuration files in the environment have become pretty much unnecessary for the common case.
