Thanks Jerry. I've found
powerpc/arch/powerpc/boot/dts/mpc832x_mds.dts
... but when I try to compile it I get an error:
$ /opt/freescale/ltib/usr/bin/dtc -I dts -O dtb powerpc/arch/powerpc/boot/dts/mpc832x_mds.dts
DTC: dts->dtb on file "powerpc/arch/powerpc/boot/dts/mpc832x_mds.dts"
syntax error at line 14
FATAL ERROR: Couldn't read input tree
Perhaps my dtc is out of date - it came with the BSP from freescale which uses
the 2.6.11 kernel.
Do you know where I can find an up to date dtc? Is there any documentation regarding its use?
Regards,
Alex
