General question in 2 parts
(so general I know the information is somewhere but can't find what I need in the way I'm asking...)
{1] building for the imx28evk, I'm prompted by bitbake to choose between different 'levels' of functionality:
core-image-minimal
meta-toolchain
meta-toolchain-sdk
adt-installer
meta-ide-support
Is there a description somewhere of these pre-defined options?
I'm after a 'development build" i.e. where I can compile on the target - console only no UI needed
This is while I learn to run with NFS to my Ubuntu host.
[2] eventually I will need to choose the contents of the file system. Is there a "How to" for that?
Most images would (and should) have some information on the actual .bb file as comments or in a separate readme file.
That being said the core-image-minimal option is as the name implies a minimal image for the i.MX28EVK that does not have graphics support so perhaps it will indeed suit your needs.
Some of the recipes you mentioned are actually not from images but from other kind of packages like meta-toolchain which serves to extract the toolchain in order to manually compile the kernel or other source code. You may find information on this feature in the following community document:

I would recommend looking at the Yocto Reference Manual of the poky version you’re using (1.7 for dizzy, link below) as you would need to create an image recipe in order to add the desired existing packages and the new packages that you would write.

I hope this information helps!
