How to debug my applet on a real card

[pitbar]

I want to debug my java card applet on the real card. I mean I can set some breakpoints in my applet source code and the execution flow on a real card can stop when coming across these breakpoints. How can I do this? Could anyone give me some pointers? Any answer will be much appreciated.

It seems that you can not debug your applet in the real card.

But there is a flexible method to reach your aim.

Add code to your card that will throw a known exception at a known point in the execution flow. When you see the status word for an exception, you know you have reached a certain point.

Hello bro.

Thanks for your help!

But actually I want to monitor some values during the execution flow. What can i do? Is there any method?

The flexible method I mentioned may be the optimal approach.

Probably, you need specific and proprietary hardware to do what you need.
