I use ELDK to cross-compile.
1.mount the ppc-2008-04-01.iso
2../install -d /home/********* ppc_6xx
3.modify the .bashrc : PATH=$PATH:/home/****/bin:/home/*****/usr/bin
CROSS_COMPILE=ppc_6xx-
export PATH ARCH CROSS_COMPILE
4.unzip the linux-4.4.200.tar.bz
5.make ppc6xx_defconfig shows:
HOSTCC scripts/basic/fixdep
HOSTCC scripts/kconfig/conf.o
SHIPPED scripts/kconfig/zconf.tab.c
SHIPPED scripts/kconfig/zconf.lex.c
SHIPPED scripts/kconfig/zconf.hash.c
HOSTCC scripts/kconfig/zconf.tab.o
HOSTLD scripts/kconfig/conf
#
# configuration written to .config
#
(here supposed to have a .config file correspond to ppc6xx)
6.make uImage shows:

7.the final step will be :make t4240qds.dtb(what is the use of this .dtb file ,is this one the same as the uImage-t4240qds.dtb installing t4240 linux system？ )
PS：Another question:when I use root to get into the t4240 linux system ,what commond can I use to transport the file and the whole folder to t4240
Thanks a lot !
