Hi,
I have an evaluation board CYW43907. On the SoC, there is a Cortex-R4 core.
I am trying to trace it. But In the debug ROM table, I only found two "Cortex-R4 Debug", no ETM(Embedded Trace Macrocell ).
(I still don't why there are two "Cortex-R4 Debug".)I checked BCM43907 datasheet, it says:
"Using multiple technologies to reduce cost, the ARM Cortex-R4 enables improved memory utilization, reduced pin overhead, and
reduced silicon area. It also has extensive debugging features, including real-time tracing of program execution.
"
Sounds like it has ETM or similar things. I am wondering someone can give me a hint about this.
Thanks
Solved! Go to Solution.

Hi,
CYW43907 doesn't support ETM. It do support standard JTAG/SWD support for debugging purposes but the SWD functionality haven't been tested from our side.

Thanks
What about the cortex-m3 in cyw43438? In the datasheet, I saw they draw the ETM in the block diagram.
I am about to try it. Please let me know if you also familiar with this one, thanks
