Re: [hatari-devel] MEMWATCH freezes Hatari

Hi,

There are several things I observed when testing more:

1. The resolution I was using in TT high mode was 1280x1024 pixels. With
1024x960 I do not get a double bus fault (with 8 MB ST-RAM and 16 MB
TT-RAM) anymore with PD but a segmentation fault:

#0  0x00005555578a4f00 in regs ()
#1  0x0000000000000003 in ?? ()
#2  0x0000555555ec643f in get_iword_mmu030c_state (o=4)
    at /home/us/hatari/hatari/src/cpu/cpummu030.h:781
#3  op_41e8_35_ff (opcode=<optimized out>)
    at /home/us/hatari/hatari/src/cpu/cpuemu_35.c:16676
#4  0x0000555555937dcb in m68k_run_mmu030 ()
    at /home/us/hatari/hatari/src/cpu/newcpu.c:6623
#5  0x000055555593339a in m68k_go (may_quit=<optimized out>)
    at /home/us/hatari/hatari/src/cpu/newcpu.c:7719

2. With no ST-RAM and 4 MB ST-RAM PD seems to work.
3. With 8 MB ST-RAM there is a double bus fault again.

Best regards

Uwe
