Hello,
I suppose you have installed Processor Expert for i.MX in an Eclipse installation and you have a compiler installed (e.g. GCC ARM). The Processor Expert generates C source code files only, there is not provided toolchain configuration. You must install plugins and/or tools for your debugger.
For example, if you have Segger j-link you can install GNU ARM Eclipse plugins, CDT, toolchain, build tools and debugging tools. You can find all instructions on page How to install the GNU ARM Eclipse plug-ins?
GCC ARM Embedded can be download on the webpage GCC ARM Embedded project files : GCC ARM Embedded
You can find instruction how to iconfigure the J-link debugging Eclipse plugin on page The J-Link debugging Eclipse plug-in
Best Regards,
Marek Neuzil
