Hi Tony, [quote userid="35100" url="~/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1500458/xds110iso-evm-trst-is-not-connected-to-emulator"] #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? [/quote] XDS110ISO-EVM is for SOM-based EVMs. For a standalone XDS110 emulator, I suggest the TMDSEMU110-U debug probe .

Is XDS110ISO and LP-XDS110 connector designed for lauchpad dedicatedly? The connector pin assignment is different with: https://www.ti.com/tool/TMDSEMU110-U [/quote] 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). Regards, Brennan
