Using D-Bug12 v4.0.0 with external RAM | 68HC12

Join our technical discussions about Freescale Microcontrollers: M68HC12. (Freescale Semiconductor is a Subsidiary of Motorola).

Hi, Is it possible to change D-Bug12 v4.0.0 in order to start the HCS12 256K in "Expanded Wide Mode"? I was planning to use the 0x4000 to 0x8000 address space for external RAM and keep the FLASH mapped between 0x8000 and 0xFFFF... Thanks, /Cilo __________________________________________________

Cilo, You can utilize D-Bug12 in Expanded Wide mode on the MC9S12DP256, however, you cannot turn the lower fixed page off as D-Bug12 uses this area for the erase/programming driver code for all the supported MCUs.

Cilo, You might want to consider using BDM instead of trying to get D-Bug12 to run on your expanded-mode embedded system. HC12 systems don't usually have a debugger in memory. What one does instead is to have two CPUs: one runs your software, and the other runs the debugger. They communicate via the BDM interface. This setup is much nicer than a memory-resident debugger.
