Other Parts Discussed in Thread: TMDS570LS31HDK
We are attempting to collect timed data markers from our software using a TMDS570LS31HDK development board and a Lauterbach PowerTrace debug unit.
On other projects, we have used the “Stimulus Ports” provided by the ARM ITM or STM within the processor.
The TMS570 instead has an ETM, which does not appear to offer the “Stimulus Port” capability.
We have attempted to output markers by writing to a specific memory address, and using the Lauterbach PowerTrace to trace writes to the particular address.
This works, and we can collect the data markers, but the times reported do not match the time that the markers were written by the software.
Can you suggest any alternative method that we could use to collect timed data trace markers?
