Their is PSoC own discussion Forum.

Else go the cypress site and then navigate to that part.

Regarding to your problem,
I think, you have connected both the Vcc1 and Vcc2 of the l239d with the same supply point which is given to PSoC and thus landed in a position where the L239d didn't able to soruce enough current to motors. Remember the each I/O pin of the PSoC can able to supply only 20 ma of current.

Try with this method. Connect the Vcc1 pin of L239d with the normal supply which is connected to PSoC and supply Vcc2 of the l239d with the source having enough current supply capacity.
