Hi,
Most of our tests are fully automated and unattended. Our FW verification team occasionally needs to watch state machine behavior while exercising various embedded functionality. They are not allowed to instrument the code and they are also to avoid anything that would change the way the hardware behaves (for example we don't want to trigger a breakpoint or in any way influence hardware behavior e.g. DMA access). Some times the number of memory locations that need to be watched are more than 10. Streaming trace looks like the way to go, we would just filter.
The ULinkPro has proven its mettle. Our only problem, is that as far as we can tell there is no way to script the probes functions without reverse engineering it. We don't see an SDK. Segger has such an SDK for their J-TracePro, but the SDK currently doesn't support continuous streaming trace, as it mainly targets the
JTAG/SWD/SWO tagged because acronyms trigger spam warning
debug stuff.
Our target device is an M4F SoC that does not support ETB but does support ETM (4 wire) and runs around 64 MHz and we can successfully trace it using the Keil MDK Cortex IDE. What we want is the ability to write C, C++ or C# code to automate the probe.
Thanks!
