In order to see the real problem with dtc, you will need: http://lists.denx.de/pipermail/u-boot/2012-June/125967.html The problem is as follows: > /home/swarren/shared/git_wa/u-boot/arch/arm/dts/tegra20.dtsi:3 syntax error > FATAL ERROR: Couldn't read input tree > make[1]: *** [dt.dtb] Error 1 This is because tegra-trimslice.dts contains: > /include/ ARCH_CPU_DTS which is run through cpp to substitute the correct absolute path: > /include/ "/home/swarren/shared/git_wa/u-boot/arch/arm/dts/tegra20.dtsi" However, some versions of dtc appear to have a problem parsing this path; perhaps it's the leading /? So, the quick solution here is to upgrade your dtc to a version which isn't broken. However, the whole reason this complicated cpp mess is being used in the first place is because older versions of dtc had no -I (include path) directive, and the tegra20.dtsi file is in a different directory to tegra-trimslice.dts. Two solutions were possible: a) Force everyone to use a newer dtc. Wolfgang rejected this. b) Do the cpp hack. U-Boot went with this option. c) Check a copy of dtc (source) into the U-boot source. The kernel went with this option. Evidently (b) causes problems with some older versions of dtc too, so isn't a complete solution:-( Perhaps the solution is to remove this cpp hack, and check in a symlink in each directory containing *.dts that need to include others. That way, we could get rid of the absolute paths that some versions of dtc doesn't appear to like. I will give that a shot. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
