CCS/TMS570LS0432: Real time debug

Part Number: TMS570LS0432
Other Parts Discussed in Thread: LAUNCHXL2-TMS57012, LAUNCHXL2-570LC43

Tool/software: Code Composer Studio

Hi,


I am still not able to monitor the variables within the watch window of CCSv6 on a TMS570LS0432 launchpad.

The watch window of CCS is showing correct und updated values only when the programm is halted.
However in my application it is essential to view the variables online during program excecution.

I would appreciate any help and advice.

    Hello Nobby,

    The TMS570LS0432 does not have the ability to update debug information without halting the CPU. This is due to an optimization that was made on this series of devices (TMS570LS0432/332/232) since they are the low end of the Hercules family of devices in both feature content and performance. The next level of devices would support this debug feature (TMS570LS07x/09x) but I do not believe they are available in a Launchpad. However, there is a 100pin version of the LS07x that is pin compatible to the 0432 (default pins only not muxed pin outs) so you could purchase a sample 100pin 07x and replace the 0432 on the launchpad if so desired (caution to investigate the differences highlighted in the application note proddms.itg.ti.com/.../spna204a.pdf that discusses migration concerns (it covers the LS04x device even though not explicitly stated in the title or scope section).

    If you are open to getting a new launchpad and a more feature rich device, both the LAUNCHXL2-TMS57012 and the LAUNCHXL2-570LC43 launchpads have devices that support the feature you are wanting.
