If you are doing a lot of difficult debug I have found the simulator in the ACR gcc suite very good. I have been doing mixed C and assembler debug of timer interrupt routines and the simulator is clock accurate for the whole process.

I also find the JTAG ICE Mk2 is good, but you can buy a lot of CM5 boards for the price. And you need to make special wiring to the board.

I'm sure It must be much more than 20 times a day. You don't count when you love ^^

But tell me if you have a CM5 older than 1 year.

my work consist amongst other things to program industrial automated machines.
For the last plant I programmed, I used a software that increment each build Nr at every little modification done on site. If I just have a look on one of the programms of the plan, the version Number is 71 126 , for less of 4 mounths of tests (realy build and transfered in the machine)... and it's only mine, not the bigger version nr of all the softwares of the plant.

Absolutely. Do the math.

If you reprogramme your controller twenty times per day you can work every day for over a year before worrying.

If you've developed that much code for your CM-5 I think it's fair to say that you wouldn't resent purchasing a new chip/PCB...

Hello,

I'm just reading Atmel documentation of Atmega128.

Page 18: "The Flash memory has an endurance of at least 10,000 write/erase cycles"

This seems to be very poor, especially during a debugg session.

Ok it's a normal characteristic for a Flash, but what do you think about that ?

Is there a way to run program in ram ?

Should I try to change frequently the start adress of the program to balance it's use ?
