How to read code from chip?

[arthurhsu]

Hi there

As title,I would like to read the code in the kinetis chip and backup using codewarrior 10.2.

Anyone know how to do it ?

Best regards

Hi Arthur.

I have the next for get information about the MCU:

Dear Evgeni

Much thanks your reply

The answear is not what I want;but I have to thank you

It's a a useful program

Let me describe the question

There is already a code in my kinetis chip,if I lost the original code

I would like to read back the binary code from chip

The answear is

I have to build a emtry project and get in debug mode by RAM

then I can export binary code from memory panel

This is method I know

Best regards
