Hello, I hope someone could help
I am developing Occam programs under D700C (beta 2 release)
and I have some interesting problems running my Occam
programs.
When I load a network of Transputers (T212 or T800) the
programs run randomly and I get a lot of error-flags set. When
I use the network debugger to see what went wrong, the
instructionpointer is way out of bounds. This is true for
every processor but the first in the network. I did a lot of
work trying to figure out what was wrong with my program, and
I also tried to run small simple programs but they acted the
same way. Only the first processor was running ok, all others
acted randomly.
When I studied the program I noticed that the entry point of
the program was different for the first processor, it was
higher. The memory map for every processor in the network is
obtained by running the Config-Info utility. That was also
what it supposed to be according to "Software Tools", chapter
6 "Loading transputer networks" (minimum code load point).
The I tried to include a dummy BYTE arry, so big that all
processors had the same entry point. And suprise, suprise it
worked. Funny (?).
Now, when I fixed the bug in the program, it put me to wonder
WHY. Is it the compiler, linker or loader ??????
Is there anyone who could give an answer.
Thanks Tor-E Malen
