how to visualize register of a micro without programming?

Hi,

I have to make a source code from 0 on a microship MCF51CN128. I have the microship already programmed but i don't have the source code.That's why i have to recreate the whole code (with few modifications). the code itself is not a problem, but the register configuration is really difficult because i don't know the exact configuration of the communications used (i know it's I²C and UART but even after analyzing their frames with an oscolloscope, it's hard to tell how it's configured).

My question is : is it possible to vizualise the register configuration of the actual program on the card with the debugger WITHOUT programming it ? I use Codewarrior with a Multilink universal.

( by the way i know it kinda sounds like hacking but there is nothing illegal right here, all the products are mine).

Thanks for your help !

Hi Adrien Segura,

Which version of CodeWarrior do you work with?

Hi Adrien Segura

In a debugging session, the CodeWarrior Attach launch configuration skips setting up the target hardware, and downloading the program image to that target hardware. The code image might reside on the target hardware already, or you might want to skip setting up the target hardware. Like the CodeWarrior Connect launch configuration, the settings in the Arguments and Environment panels do not apply.

 

See below screenshot of where to use it:

For more information, please search help file with keyword “CodeWarrior Attach”.

 

 


Have a great day,
Jun Zhang
