Part Number: XDS110ISO-EVM
Other Parts Discussed in Thread: LP-XDS110,

Tool/software:

#1. In XDS110ISO schematic, there is not TRST on emulator connector. I want to use this emulator to connect Sitara AM62x device, Is TRST pin needed?

While it is there on LPXDS110 schematic.

#2. There is not RTCK signal on connector also, is it implemented inside the XDS110 core device MSP432E401YTPDT

#2. Is XDS110ISO and LP-XDS110 connector designed for lauchpad dedicatedly? The connector pin assignment is different with: https://www.ti.com/tool/TMDSEMU110-U

    XDS110ISO-EVM is for SOM-based EVMs. For a standalone XDS110 emulator, I suggest the TMDSEMU110-U debug probe.

    XDS110ISO-EVM is designed for controlSOM EVMs. The LP-XDS110 is designed for LaunchPads that have been split and have the corresponding 20-pin edge connector.

    If you are trying to connect to the AM62x EVM, use the debug probe I suggested in (1).
