Hey the good news is that you've updated your build system to support also appended dtb images, thanks for doing that! > Any ideas? Looks like you need some things updated and added to your .config. -# CONFIG_OMAP_MUX is not set +CONFIG_MACH_OMAP_GENERIC=y That we should nowadays always select though. CONFIG_REGULATOR_FIXED_VOLTAGE=y This you will need for Ethernet. CONFIG_PINCTRL_SINGLE=y This is good to have, will be needed especially for for UART wake-up events with deeper idle modes enabled once the pending pinctrl patches are merged. Also, can you please add these for NFSroot: CONFIG_IP_PNP=y CONFIG_IP_PNP_DHCP=y CONFIG_ROOT_NFS=y That way I can also boot test your .config on regular basis ;) Then there's a pending patch to change drivers/i2c/busses/i2c-omap.c to use just a regular module_init, that should remove the i2c timeout errors as then deferred probe will work properly. BTW, maybe add a link to your build system to www.arm.linux.org.uk developer page too? At least I could not find a link to it.
