How to Use Instrumentation Trace Module to Debug on TM4129DNCPDT

Other Parts Discussed in Thread: TM4C129DNCPDT, SEGGER

Hi,

I am using TM4C129DNCPDT and facing some issues. I want to debug and keep trace on some variables and also the interrupts coming while run. I am using CCS as my developement and debug enviornment. I have heard of ITM that it is an application driven trace source that provides a high level software view of what is happening on the device. ITM enables features such as: Statistical Profiling, Variable Tracing and Interrupt Profiling. I tried to see it it is supported for TM4C129DNCPDT, i found that it has support for ITM(Instrumentation Trace Macrocell). Is it the same? If yes, can anybody help me for how to use i while debugging. I am using XDS200 usb emulator as a debugger.

Thanks in Advance.

Regards,

Shrikant

    Hello Shrikant,

    I think CCS does not have the Trace for Cortex M4F devices with XDS2xx. You may want to check on the Code Composer Forum.

    If you're willing to expand your use from CCS to IAR - and acquire a J-Link (pod) -  much of that you seek becomes enabled.

    If interested - visit to Segger's site further details.  

    IAR under J-Link well enables SWO which provides a reduced cost/size trace while avoiding the cost & signal demands of full-scale trace...

    Hello cb1

    J-Link and I-Jet are different (sorry for my ignorance) as someone did ask me about I-Jet Trace. May you please enlighten this vendor rep!!!

    Hi Amit,

    Staff here are evaluating I-Jet for our small firm's upgrade. Rather than my (incomplete) report - may this wait till their return (late today)?

    There are multiple grades of "J-Link & beyond" - and substantial differences in price.

    Real (full) trace does seem to demand a major connector & board dedication to that, "trace process." Yet - with that commitment comes greatly enhanced insights into, "where the MCU's been - what its done - & when!" This does come at a great financial and board-size cost - as each case proves different (as you well know) forming a general usage rule is beyond this reporter's pay grade.

    Poster Robert may "know I-Jet" cold - but I will respond (later) in his absence...
