I use the m68k/efi332 BSP together with a home made board. After some time of debugging I found that the m68020 CPU is used to build rtems. This is not correct, because the 68332 does not have some of the 68020 features (no separate int stack ...). It is necessary to change this to mcpu32. After a clean/make everything works fine.
