DM814x : CCS loading M3VPSS symbol issue

Hi I am using CCSv5.5 _ xds 560v2 use emulator, trying to run HDVPSS standalone.

when I load M3VPSS firmware(xem3 symbol, pre build and newly build), it will return error as below:

Cortex_M3_ISS: Breakpoint Manager: Retrying with a AET breakpoint
Cortex_M3_ISS: Breakpoint Manager: Error enabling this function: Address exceeds the allowed range
Cortex_M3_ISS: Trouble Setting Breakpoint with the Action "Terminate Program Execution" at 0x8c8447e4: (Error -1170 @ 0x8C8447E4) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.1.232.0)

I have checked the breakpoint window but there is no break point set.

Could you give me some idea what might cause this issue?

BR,

Eason
