Re: [hatari-devel] 060 + DSP -> freeze

[Laurent Sallafranque <laurent.sallafranque@xxxxxxx>]

I've added the following line into m68k_run_3p() and m68k_run_3ce()

#ifdef WINUAE_FOR_HATARI
            /* Run DSP 56k code if necessary */
            if (bDspEnabled) {
                fprintf(stderr, "currcycle = %d\n", currcycle); <-- 
this one ;)
                DSP_Run(2 * currcycle * 2 / CYCLE_UNIT);
            }
#endif

I get a huge value for currcycle, which explain why the DSP runs all the 
time.
Currcycle increase all the time to a huge value.

[...]
currcycle = 159398400
currcycle = 159398912
currcycle = 159399424
currcycle = 159399936
currcycle = 159400448
currcycle = 159400960
currcycle = 159401472
currcycle = 159401984
currcycle = 159402496
currcycle = 159403008
currcycle = 159403520
currcycle = 159404032
currcycle = 159404544
currcycle = 159405056
currcycle = 159405568
currcycle = 159406080
currcycle = 159406592
currcycle = 159407104
currcycle = 159407616
currcycle = 159408128

Maybe it is not reseted or something like that.
