Where is folder/file "config/kernel.release"?

Hi,

I install L138LCDK on Ubuntu 12.04. Then, I unzip kernel under path:/home/lcdkl138/ti/ti-sdk-omapl138-lcdk-01.00.00/board-support. A new folder linux-3.1.10 is generated under board-support.

I modify products.mak under folder syslink_2_21_03_11 with the required path options. When I make the syslink, it generates the following error:



lcdkl138@lcdkl138-XPS-8500:~/syslink_2_21_03_11$ make syslink
makefile:472: *** LINUXKERNEL is set to "/home/lcdkl138/ti/ti-sdk-omapl138-lcdk-01.00.00/board-support/linux-3.1.10", which is invalid (could not find file "/home/lcdkl138/ti/ti-sdk-omapl138-lcdk-01.00.00/board-support/linux-3.1.10/include/config/kernel.release"). Set this in <SysLink Install>/products.mak. Refer to the SysLink Install Guide for more information..  Stop.
lcdkl138@lcdkl138-XPS-8500:~/syslink_2_21_03_11$


I check folder under linux-3.1.10/include, there is no config folder. What is the problem?

Thanks,
