Hi,everyone,I had a problem when I cross-compile with commond I use "make ppc6xx_defconfig",it supposed to have a .config file ,but I couldn't find it.

In the next step，I use "make uImage",it shows

make[1]: *** [arch/powerpc/kernel/pmc.o] Error 1
make: *** [arch/powerpc/kernel] Error 2.

I'm using ubuntu 14.04,ppc-2018-04-01.iso,linux-4.4.200.tar.xz

Would you please provide the whole build console log?

What GCC build parameters did you use?

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:

# 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 !

ppc-2008-04-01.iso doesn't support T4240, please download and install Linux SDK 2.0 from Linux® SDK for QorIQ® Processors | NXP .

t4240qds.dtb is same as uImage-t4240qds.dtb.

You could use "scp" command to copy files to T4240 target board.
