TRACE Interface through FPGA on Intel's Agilex 7 device not outputting clock
Hi.
I am trying to validate a TRACE interface coming from Agilex’s HPS through the FPGA IO to a Mictor connector, but I am having issues getting the TRACECLK to show up. Currently I have a DSTREAM-PT interface working and can see the TRACE DATA signals toggling but not the clock.
I added to the HPS Core the 16-bit width TRACE interface through Quartus, and made the Coresight Trace clock 50MHz as it’s the slowest to make sure we could see a clock. After synthesis I see the trace_s2f_clk output is actually connected from the S2F module as TPIU_TRACE_CLK to the IO pins but once we run a test through the ARM-DS I don’t see a clock coming out of the pin, but I do see data toggling through a scope
I also made sure that looking at this register all clocks were enabled
I find there is a lack of documentation about this feature and haven’t been able to find the reason of it not working. Am I missing something that I should be enabling either through Quartus or through a SW register? Any suggestions to look at?

Hi Fdominguez,
May I know if there is further respond on the matter?
Do let me know if you require more time to setup/route and test on the HPS IO for the trace clock?
Thanks.

Hi Fdominguez,
I will close this thread if possible. If there is a further follow up with signal probing to the HPS IO, do consider open a new thread on the matter.
Thanks.
