How to build Linux 3.10.17 for iMX6?

Hi,

 

There should be three things I need to build: rootfs, kernel, and uboot.

I downloaded kernel from here: linux-2.6-imx.git - Freescale i.MX Linux Tree, and uboot from here: uboot-imx.git - Freescale i.MX u-boot Tree. But I couldn't find where to download rootfs. Could somebody help?

 

With the cross-compiler installed previously, I built kernel by doing this under the root folder:

  1. exportPATH=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/:$PATH
  2. export ARCH=arm
  3. export CROSS_COMPILE=arm-none-linux-gnueabi-
  4. make imx_v7_defconfig
  5. sudo apt-get install lzop (need to install zlop)
  6. make uImage LOADADDR=0x70008000 (need to specify load address to avoid build error)

The output file uImage was put under ./arch/arm/boot.

 

I then tried to build uboot. The first three steps are the same as above. But at step 4, I couldn't find a config file in the whole uboot tree. Can somebody tell me how to build?

 

I used this as reference: Linux booting on IMX6 SABRESDB. I tried to follow Ed's notes, but when building uboot, I also couldn't find the config file.

 

Thanks a lot.

Jason
