If you are on 4.10 or newer, the MyBSPName is detected automatically based
upon the set of files with a name like this:
You can build multiple variants of a single BSP and that makes
a BSP directory represent a family. The ".cfg" file is the specific
name of the BSP you can build.

There is a BSP and Device Driver Guide in the document set.
The general approach is to find a BSP that is close and either make your
custom board a variation of that. If your board is close then you add a
make/custom file and then account for the differences via a combination
of configure time selection and conditional compilation.
If your board is not close enough to be a variation, then you make a new
BSP family directory and populate it. Start by copying from BSPs that
If you need help, this is the type of consulting I like to do. Pair
a BSP is a very efficient way to get one. You know that hardware and we
know the structure of the BSP and RTEMS issues.
