Problem: I would like to change Reset address (0x0000) to another one (0x800000) in the MONITOR Mode, because in our hardware RAM starts at this address. I am able to load my program into RAM using bootstrap mode and my MONITOR, but I am unable to run or debug my proram. Thanks for help Aram
In uVision2: 1. In Project Options-Target Options: un-check the Use on-chip RAM and Use on-chip ROM check boxes. 2. In Project Options-Target Options: under External Memory enter the appropriate ROM range and RAM range. ROM will probably be starting at 0x80000 (for a length of 0x8000) and RAM will probably start at 0x88000 (for a length of 0x8000). 3. In Project Options-L166 Misc: enter 0x80000 for the Interrupt Vector Table Address. 4. Be sure to include the START167.A66 startup file in your project. Rebuild your project and take a look at the MAP file. You should see everything in the correct place. I tried this with the HELLO example program. Following is the MAP file output from that build.
