Oops, bit slow off the mark as I just got back from overseas.  We also 
roll our own tools for use under msys, and it was a while ago and forgot 
that the standard toolchain is not built with m5307 support!

I agree that it looks like a 68020 instruction, so we need to check the 
build commands.

Kevin, you indicated in your first email that you created a new BSP. 
Would you mind sharing your config file from the rtems-4.7/make/custom 
directory so we can check your build options?

regards,

Ian Caddy
