What is the difference bettween debugging and running independently

Other Parts Discussed in Thread: TM4C129XNCZAD

I have a custom board with a TM4C129XNCZAD and using a Stellars ICDI Emulator.
I am writting the code interface to ET1100( an EtherCAT slave chip), it is in epi hb8 mode.
When I program and debug using the ICDI, the communication with ET1100 is ok.
When I quit the debugger and power the board down and back up, the TM4C129 running independently, the communication is error.
I want to know What is the difference bettween two situation?
Thanks!

Hello Jian,

From an application point of view both should be same. However when running in debugger mode and based on the settings the code may behave differently since in debug mode between multiple program executions the device may not be fully reset.

In the case mentioned in your post, you would need to see what is not working (debug). Connect the debugger back to the device w/o loading the code and see where the program execution is stuck.

Amit

Hello Amit,

I run it in debugger mode just after power on. Is it likely caused by gel file?

Best Regards.

Hello Li,

The gel file may not cause such a problem. When you connect the debugger w/o loading the code, what does the CPU register show?
