Hello Shantanu,

The instruction of "vmrs r12, fpscr" causes the issue. Is the float-point feature enabled? Is the runtime library for floating-point used?

If the floating point is disabled, any calling floating-point instruction will cause undef exception.

Is floating-point disabled in sys_core.asm?
