Hello,
I downlaoded an evaluation version of PK166 v7.4, and write a very very simple main function for XC2364B, when I try to debug in the simulation mode, it reports the error "error 65: access violation: addr=0x0000A000". Does PK166 v7.4 support the simulation of XC2364B?
Thanks, Simon
You haven't (correctly) configured your memory map.
Hello Andrew,
Is it possible to use Debug->Memory Map to change the memory maping of target system? I try to change it via the menu command Debug->Memory Map, but each time I re-enter the debug mode, the modified memory map configuration is lost.
Thanks.
i have the same probelm,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, give me answer
Yes, as the name suggests, that is what the MAP command does!

Are your memory setings correct in the project options?

I checked the memory map, it is as below:
001: 0x00000000 - 0x00009FFF exec read write 002: 0x0000A000 - 0x0000A23F read write 003: 0x0000A240 - 0x0000F5FF exec read write
According to the map file (.m66), my code is allocated as below:

The MCU XC2364B that I am using, the memory from the address 0x00A000 to 0xDFFF is Data SRAM. Everything looks OK, but the deggguer report the error "*** error 65: access violation: addr=0x0000A000", and in the Disassembly window, it stop at the address 0x00A000 and it looks like:
0000A000 0000 ADD R0,R0 .... ....
Now I have no idea why this happen because the memory map configuration looks correct.
Have you noticed that there is a 'Search' box at the top-right of the page...?
