Hello, I am using DS-5 with a DStream-ST probe connected to a processor with a Cortex R5 core & dual Cortex M7 cores.
I am able to connect to the R5 processor, single-step, set breakpoints, etc.
However, I am unable to issue a JTAG reset to the Cortex R5 using the "reset jtag" command. When trying to do so I receive the error:
"ERROR (CMD463): The reset capability jtag is not available"
If I issue the command "info capabilities", I see the following:
Reset options
System Reset
Available while running == true
My debug connection is from the DStream-ST ARM JTAG 20 connector to my board and has both nTRST (pin 3) and nSRST (pin 15) connected.
Q: How do I enable the "reset capability jtag" in DS-5?
I am using DS-5 Ultimate Edition v5.29.3, Build 5293015 with an evaluation license (our corporate license expired 12/18/2021).
Q: Could this problem be related to the use of an evaluation license?
Thank you,

HiThe Debugger/DSTREAM sometimes uses this "soft TAP reset" mechanism itself (hold the TMS high for 5 cycles) for its own internal purposes but, sorry, there is no Debugger command or GUI control available for the user to trigger this. Doing so could result in the TAP and DSTREAM getting out of sync, possibly resulting in a lost debug connection.Stephen
