I see, so its the expected behavior. Thats good news! I'll check setup.c,

 

Thanks for your help John !

arch/microblaze/kernel/setup.c, look for the functions

machine_restart()

machine_shutdown()

machine_halt()

and machine_power_off();

The implementation of these is board-specific, thus the default
behaviour is currently to just dump the stack and loop forever.

Longer term I'd prefer a mechanism where a machine-specific data
structure contains function pointers for these handlers, so that each
board can have it's own (like the PPC ppc_md), but it's not there yet.

Regards,

John
