I know the Cortex-M Trace Reference Board is very simple, but I'd like to compare the JTAG/Trace connection on our proprietary board with the reference board. I'm specifically curious if the nJRST pin is connected for TRACE purposes. I'm having problems tracing a large application on our board. I can't find the schematic on the Segger website.

I sent an email to support several weeks ago and heard nothing. It was for more than the schematic, now I have several forum entries to try to get my problems solved. I will send email again.

BTW, there are 2 resets involved with JTAG/SWD/TRACE. nRST for the processor core and nJTRST for the JTAG "port". J-Link/J-Trace documentation gives the impression the nJTRST is optional, I want to see if it's used on CM Ref Board. And to make things more confusing, these signals have different names with different boards/vendors. STM32F769_EVAL uses TRST for nJTRST which appears only on the JTAG connector and has the option (see R111) to appear on the TRACE connector displacing TRACED1 signal. nRST appears as RESET# and is on both JTAG and TRACE connectors.
I'm hoping that nJTRST might be able to solve the problem where the J-Link/J-TRACE isn't able to break into (halt) the processor.

Hi Niklas,

Thanks for getting back to me. The most recent email was sent to support@segger.com Sep. 6 2017 with subject "J-Trace PRO and STM32F765NI". Our custom board uses STM32F765NI, not STM32F769NI.
There was also an email Aug 18 2017 "Re: J-Link: connection to target device lost" which was a follow on to an original request of Jul 11 2017 that you may have considered solved. We did get responses from segger.com/support/technical-support/.
I understand it has been the holiday period.

Right, there is no JTAG connection on the CM Ref Board, I want to see the exact connection of the TRACE interface.

Thanks you. You can consider this request solved.

For informational purposes: nJTRST is not connected to TRACE connector, nor is JTDI which is JTAG signal not needed for SWD.
