Hi people... problems again... this time, when changing stack. In a new
update of NestorAcentos I'm developing, I put the following piece of code
attached to the timer interrupt hook. The code is placed in a reserved zone
on page 3:
ld (SAVESP),sp
ld sp,NEWSP+100
push all
.
. (changes slot and segment on page 2, do stuff and restores old status)
.
pop all
ld sp,(SAVESP)
jp old interrupt hook
SAVESP: dw 0
NEWSP: ds 100
Well, a program executing such code causes the system to crash when any
other program is executed. Someone knows where is the problem?
Thanx!
