Is there any ETMs supporting data trace in the market?

The manual of ETM tells that the ETM supports data trace. However, we checked the manual of Juno board and most recent Cortex A75 processors, and found that the data trace is not implemented. Currently, is there any ETM supporting data trace in the market?

Thanks for any help and discussion!

  • I assume you need ETMv4? Cortex-M7 should be widely available and implements ETMv4.0. You'll find data trace in processors that are less complex, which rules out ever seeing it on a Cortex-A processor, although I believe some of the older or more efficient Cortex-A8, Cortex-A5 may have data address (but not data value) trace on older ETM architectures.
