Hello All,

I am beginner with respect to Q2687 kit. Now I ran a sample program and want to debug. Now, I have some very basic questions regarding the same…please kindly respond

1. Which is the best and easy way to debug a program on Q2687?

2. If I need to use J-Link, How do I interface J-link-ARM to Q2687 and what additional software do i need to install ? what should be the debug mode(RTE/Target)

3. Is it possible to debug using GDB hardware debugger alone?

Thnks n regards,  
Sameer
