Linux/AM5728: SDK build issues

Part Number:AM5728

Tool/software: Linux

Hi,

Attempting to compile & install modules using Processor SDK Linux 4.3 - install doesn't appear to work

I'm trying to rebuild the kernel, modules and device tree binaries by following these steps:

• make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- distclean
• make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- tisdk_am57xx-evm_defconfig
• make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage
• make ARCH=arm CROSS_COMPILE=../../linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linux-gnueabihf- am57xx-beagle-x15-revb1.dtb
• make ARCH=arm CROSS_COMPILE=../../linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linux-gnueabihf- modules

This appears to complete with no issues.  However, when I go to install the modules:

• export CROSS_COMPILE=arm-linux-gnueabihf-
• sudo make ARCH=arm  INSTALL_MOD_PATH=/home/dmurphy/my_build modules_install

Unfortunately, the "sudo make ARCH=arm INSTALL_MOD_PATH=/media/rootfs modules_install" command from the link below doesn't actually install the modules in the INSTALL_MOD_PATH.

http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components.html#kernel 

In fact, to run the command with sudo, I have to change the command to avoid gcc being picked up instead of the arm cross compiler:

sudo bash -c ' export CROSS_COMPILE=../../linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linux-gnueabihf- ; make ARCH=arm INSTALL_MOD_PATH=/home/dmurphy/my_build/modules/ modules_install'

Regardless of whether I use sudo or not to make modules_install, nothing ends up in the INSTALL_MOD_PATH directory.  After some time, the Make just ends abruptly with the following output:

...

Any assistance would be greatly appreciated.

Thanks,
