The kernel configuration portion of the TCT is nothing more than the standard 'make xconfig' mechanism found in every Linux kernel source tree.
Kernel configuration issues are described elsewhere on this website and are not gone into detail here. Please refer to this link for kernel configuration recipes.
It is worth mentioning at least one reason why the kernel configuration portion of the TCT should NOT be used and is detrimental to rapid-prototyping of your embedded Linux project.
The build or make mechanism in version 2.1 TCT is overly cautious. Whenever a change is made to either the kernel configuration or the filesystem package selections, the whole thing is re-built. Now it can be argued that you may want to rebuild the whole kernel if you make a kernel configuration change. But it is hard to argue that if you add a package to the filesystem that the kernel needs to be rebuilt in it entirety.
If you create a TCT project that includes a custom kernel, you are a coffee addict who likes to take long coffee-breaks. When you are experimenting with a filesystem, adding packages and subtracting packages, this is an exercise that should take no more than 1-2 minutes for the tool to complete. When the project includes a custom kernel with the filesystem, the 1-2 minute turn-around time grows to 10-20 minutes, depending upon the speed of your development host.
