Yes - appears the DRA829 hardware does not support your XDS110 header directly. You will need adapter (or modification) to make the following connections:

CON20A Connecter - XDS110 Connector

XDS110_TRST# - RESETn

XDS110_TMS - JTAG_TMS

XDS110_TDI - JTAG_TDI

XDS110_TDO - JTAG_TDO

XDS110_TCK - JTAG_TCK

DGND - GND

VSYS_IO_3V3 - VCC

I think the 10-pin connector might be ARM mini-JTAG connector (10-pin) . If you look around, you should be able to find some adapters (MDL-ADA2)

If I understand the log file correctly - it appears you able to connect to the DMSC (which confirms the JTAG connections), but failed when attempting to connect to the MCU. Is that correct? Have you setup CCS correctly?

Yes，you understand correctly ,it failes when connect to MCU.CCS was set up corectly,because i can debug on EVM_J721E.Is there any other errors which may cause this faults?

Your error message says attempt to run board initialization script, but then says error loading. Do you have a path/setup issue to the GEL files?
