SDK 2.0 for QorIQ : Build linux kernel

z_v — Sat, 17 Dec 2016 14:53:18 GMT

Hello,

Paragraph 3.3.2 in SDK2.0 manual explains how to rebuild the kernel using bitbake.

I want to build the kernel supplied in SDK 2.0 without bitbake but with:

cd <kerenl source>

make CC=<my arm-v7-gcc> ARCH=?

In x86 for exmaple I'm running: make CC=<my x86 gcc> ARCH=x86 (or x86_64)

what ARCH should I use here ?

Thank you,

Z.V

The SDK online documentation provides some suggestions for building
the kernel "by hand" with the SDK standalone toolchain:

(see last FAQ)

Note, there is no official support to building any SDK component
with a non-SDK toolchain.

You choud use something like below:

build kernel/uImage from sources
$ export ARCH=arm
$ export CROSS_COMPILE=<path_to_toolchain>/arm-linux-gnueabihf-
$ make ls1021a_defconfig
$ make uImage LOADADDR=0x80008000

You could also try to build kernel using CodeWarrior. Take a look on https://community.nxp.com/docs/DOC-332778 . You can ignore that document talks about CW for ARMv8, CW for ARMv7 cane be used as well.
