Re: [MiNT] -m68030 vs -m68020-60

When I try to launch a program compiled with -m68020-60 on my Firebee it stops

NB: This is related to FireTOS, not the FireBee hardware.

This behavior is by design.

-m68020-60 is compatible with 68020/68030/68040/68060 and requires a 68881 FPU (or equivalent).

FireTOS (thanks to the CF68KLib) emulates a 68060 CPU, but not a 68060 FPU (similar to 68881). This is why -m68020-60 programs refuse to work.
