WHDLoad ,Hrtmon and access fault.

Asman · 09 October 2009, 11:44

Hi,

I have problem which occurs when I write slave without kickstart emulation. When I use kickstart emu in slave then I use Hrtmon without any problems. But for slave without kick emu I obtained access fault. I found description in source kick13.s that Hrtmon read to much from stackframe - but I don't have knowledge how can I do similar thing in my slave. Any ideas how solve my problem ?

Regards

Find the stack pointer init instructions. Most probably one is set to the end of basemem, something like

Code:

lea $80000,a7

for 512k.
Replace this with a decreased by 8 value (that is used in the kickXX.s files if HRTMON is defined), e. g.

Code:

lea $7fff8,a7
