4. Be sure that the device(s) necessary to produce output on your console are correctly placed in the DT. Also make sure that u-boot knows about it (#define OF_STDOUT_PATH... in your u-boot board config file)
OF_STDOUT_PATH is deprecated; you should enable CONFIG_OF_SERIAL_VIA_ALIAS, and provide aliases in the device tree for serial0, serial1, etc.
6. Remember to always specify the "rootfstype=" option on the commandline if booting from anything other than NFS. This was not necessary back in the 2.6.15-times AFAICR.
It still should not be necessary.
7. Boot with a device-tree (in u-boot: "bootm $addrofkernel - $addrofdtb", don't forget the dash if you are not using an initrd). If you don't do this, u-boot can't fix your DT, and the kernel probably won't find it either.

8. Be sure to use the correct version of the DTC (DT compiler) for your kernel (the sources are included nowadays, somewhere in arch/powerpc/boot IIRC). The command used to compile, should probably be something like this:
Or just use the most recent DTC. -Scott _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
