yeah but, hey, it should never happen. CPUs don't melt any more when you push them that hard anyway, usually they slow themselves down or in some cases reset. I don't think it's a real issue. Also, recall that it will be doing a lot of IO, not computing pi :-) > > Can't we clear the FIFO any other way and go to CPU hlt afterwards? > No, because of JTAG. I've had really terrible problems with JTAG debuggers when CPUs halt. Even a tight loop (while (1);) can be hard to break into on some CPUs. But if the CPU is in a call/return-with-IO type mode, it is pretty easy to grab it with JTAG, stop it, and debug it. thanks ron -- linuxbios mailing list linuxbios@linuxbios.org http://www.linuxbios.org/mailman/listinfo/linuxbios
