Hi,

I want to know busybox cross compile option.

In my target board, following error occurred.

#################################################

RAMDISK: squashfs filesystem found at block 0
RAMDISK: Loading 12796KiB [1 disk] into ram disk... done.

my environment :

host : ubuntu-14.04.3 64bit

am3352

ti-processor-sdk-linux-am335x-evm-02.00.01.07

my busybox cross compile option :

PATH="/opt/ti-processor-sdk-linux-am335x-evm-02.00.01.07/linux-devkit/sysroots/x86_64-arago-linux/usr/bin:/usr/lib/ccache:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

make install ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

ps.

ti-sdk-am335x-evm-08.00.00.00 environment was not a problem.

Hi Ahn,

Could you check whether libc.so.6 presents in the /lib folder of your board rootfs?

Hi,
/lib/libc.so.6 is exist.
I copied library from ./ti-processor-sdk-linux-am335x-evm-02.00.01.07/filesystem/tisdk-rootfs-image-am335x-evm.tar.gz.

Additional questions:
I found the following environment setup from ./ti-processor-sdk-linux-am335x-evm-02.00.01.07/linux-devkit/environment-setup.

export REAL_MULTIMACH_TARGET_SYS=cortexa8hf-vfp-neon-linux-gnueabi
export SDK_PATH_NATIVE=$SDK_PATH/sysroots/$SDK_SYS
export SDK_PATH_TARGET=$SDK_PATH/sysroots/$REAL_MULTIMACH_TARGET_SYS

What is the cortexa8hf-vfp-neon-linux-gnueabi?

Dear Ahn,
Are you using the pre-built filesystem from " ti-processor-sdk-linux-am335x-evm-02.00.01.07" ??
It seems you have modified the filesystem...

I want to know busybox cross compile option.

Did you cross compile the busybox and install into filesystem ?

Hi,

Install a filesystem has the following order.

first. I'm copy the /lib/*.so from "ti-processor-sdk-linux-am335x-evm-02.00.01.07/filesystem/tisdk-rootfs-image-am335x-evm.tar.gz".

second. cross compile opensource(ex. busybox, util-linux, mtd-utils ...) and install into filesystem.

Please make sure that you have used proper toolchain for cross compiling the busybox.

If possible compare the "libc.so.6" file from TI filesystem and your filesystem, you could see some difference.

host# file libc.so.6

Ahn,

I only would like to add the recommended tool-chain is (Linaro GCC 4.9-2015.05). You can see the used tool-chain in current build in the first rows of booting kernel log. You can see more details about the tool-chain at:
