Currently I am using HCS12 controllers. Debugging is extremely difficult due to limitations of software breakpoints (two hardware breakpoints is not enough for a source code of 256KB). I am thinking of using another freescale controller that supports software breakpoints in flash.
Can anyone tell me which controller supports software breakpoints in flash? (S08, RS08, HCSX12, Coldfire V1, Coldfire V2, Kinetis).
