In the built-in u-boot environment on some boards. Typically with u-boot variants that can support multiple similar boards; a single mx6cuboxi u-boot binary supports several cubox-i and hummingboard variants. It's typically run from bootcmd, so "printenv bootcmd" from the u-boot prompt might show something like "run findfdt ; run distro_bootcmd". >>From looking into the bootscr fdtfile needs only the filename: > > if test -n "${fdtfile}"; then > setenv fdtpath dtbs/${fk_kvers}/${fdtfile} > else > setenv fdtpath dtb-${fk_kvers} > fi > > Correct? Ah, yes, full path wouldn't work in this case- you'd have to have it in one of the above locations the boot scripts look for. live well, vagrant
