@toni - I've had time today to try out the uaedbg side loader and new printf functionality in 4.4.0.
On the uaedbg, I'm finding the debugger is breaking on instruction fetch changes.
Configuration is A1200 with Cycle exact, here's my code snippet:
Code:
agdPingPong:
tst.l .dir
beq.s .down
bmi.s .up
bra.s .exit
.down: cmp.w #$8c,CAMERA_YPOS
beq.s .swap
bsr agdPanDown
bra .exit
.up: cmp.w #$0,CAMERA_YPOS
beq.s .swap
bsr agdPanUp
bra .exit
.swap: not.l .dir
bra.s .exit
.dir: dc.l 0
.exit: rts
As you can see I'm using local/private variables in the code.
Whenever the not.l is executed the debugger is breaking with:
Code:
Invalid access. Addr=7000968c RW=R Size=4: Instruction fetch from memory that was modified after being executed at least once
Is there a valid reason the debugger is breaking due to this? If I was to guess what was happening I'd say the cache is being loaded and then the code is changing the value in memory causing it to break - but I'm not self modding the code.
Is there any way to disable this particular check if what I think is happening is correct?
Cheers,
Graeme
