Steem debugger

Post by slingshot »

Hi!

I've encontered a strange debugging issue: a demo loader does a memory cleaning loop, and this loop interrupted somehow before the whole memory is zeroed out. But I cannot find out the interrupting device. Turned on all of the tracing options, but what I see the CPU tracing just switches off, and no indication why. The steem.log snippet:

The loop:

Code: Select all

00109E: dbra d0,-6 {$00109A}
00109A: movem.l D1-7/A0,-(a1)
00109E: dbra d0,-6 {$00109A}
00109A: movem.l D1-7/A0,-(a1)
00109E: dbra d0,-6 {$00109A}
00109A: movem.l D1-7/A0,-(a1)
00109E: dbra d0,-6 {$00109A}
00109A: movem.l D1-7/A0,-(a1)
00109E: dbra d0,-6 {$00109A}
What happens here? The CPU tracing is turned off automatically. Also no log of any interrupts. The cleaning doesn't reach the loop code. The next entry is only a breakpoint:

Code: Select all

Break: Hit breakpoint at address $001694
Upd: hmm, seems no interrupt, just Steem automatically turns off CPU logging after a while?

Ok, the loop exits then, but why the logging?

There are some long standing issues with Steem's debugger, especially with the logging system that was changed/replaced at some pont. Unfortunately the current developer is not active at the forum for quite some time. He has his own forum, or at least a blog, I believe.
