How to build cmemk.ko
Added by Mary Frantz over 11 years ago
I need to use the CMEM utility, but there is no cmemk.ko file. I am trying to build it, but can't find any instructions for that.
I ran make from this directory: ~/MDK_2012-08-10/sw/3rdparty/linuxutils_2_26_01_02/packages/ti/sdo/linuxutils/cmem
mitydsp@mitydsp-dev:~/MDK_2012-08-10/sw/3rdparty/linuxutils_2_26_01_02/packages/ti/sdo/linuxutils/cmem$ make

Is there no file cmemk.ko that is ready to go?
It says to
"Run 'make oldconfig && make prepare' on kernel src to fix it."
What does this do? Where do you run this command from?

The base and full filesystems in the MDK_2012-08-10 (MD_2012-08-10/fs/*.tgz) each have a cmemk.ko module located in the /lib/modules/3.2.0/extra/ folder. These should be modprobe-able if are you using the uImage that comes with the filesystem.
To build it, I think you should specify where the kernel directory is located with the LINUXKERNEL_INSTALL_DIR path.
For the cmem build, our install script basically does (after configuring the toolchain):
cd MDK_2012-08-10/sw/3rdparty/linuxutils_2_26_01_02/packages/ti/sdo/linuxutils/cmem make LINUXKERNEL_INSTALL_DIR=/path/to/your/kernel/dir
If you have not built the kernel in that path before, you'll need to first configure and compile it according to the kernel build instructions first.

Thanks!
I found the cmemk.ko module in the the /lib/modules/3.2.0/extra/ folder along with dsplinkk.ko and others. Used insmod for both and ran my application which ran some CMEM calls.
