TM4C1232H6PM: Advanced Debugging with TM4C12x

Tool/software:

Hello

I'm trying to use the advanced debugging technique "Core Trace" from Code Composer Studio with a TM4C1232H6PM microcontroller.

I have found a description of the Core Trace here.

And in the Documentation of TM4C1232H6PM there are some chapters on Trace Port Interface Unit (TPIU), so I think it should be possible.

When I connect to the microcontroller using a Blackhawk USB100v2 JTAG Connector, I do not see the trace option. I assume this debug probe does not support the functionality?

How can I use the Core trace feature with this microcontroller?

Thanks for any help in advance.

Hi,

I don't think USB100v2 support Serial Trace Output (SWO) as described in https://www.blackhawk-dsp.com/products/jtag-emulators/usb100v2d.

To use SWO, you would need to something like XDS110 or XDS200. Please visit:

As you can see on the product page, core trace is supported by these debug probes.

In CCS, under the connection properties you can select SWD Mode when you use XDS200/XDS110. See below.

Thanks a lot, I will check them out.

For future reference, I also found this (much cheaper) probe, which is supposed to do the same thing, wihtout code composer studio: https://black-magic.org/
