Dear sirs, I am writing an In Application Programmaing application, and I am facing with the difficult to get the real flash content using the debugger. If I program the common flash area from 0x6000 with the values 'a'=0x61, 'b'=0x62 etc, I can see in xdata window (main flash is in xdata during programming) the correct values programmed. But, if I restore the main flash in program space I cannot view the real main flash content: the debugger shows me all 0xff: no matter of page register or so, this happens also after reset and with PAGEREG and VM with correct values 0x00 and 0x0C. But attention! I can set the PC to 0x6003, where I should have written the character 'd'=0x64. So the flash is programmed with the values 0x61 0x62 etc but the debugger don't shows me the real values! |
