AM625: AM625:M-Core Debugging

Part Number: AM625


1.Problem Phenomenon: Error reported when connecting to XDS110 via CCS 

BLAZAR_Cortex_M4F_0: Error connecting to the target: (Error -1274 @ 0x0) Error encountered during connect sequence.  The specific reason is unknown but may be the result of trying to access a Core or logic that is inaccessible due to a lack of Power, Clocks, or Authentication (i.e. Security is preventing).  If blocked by security, and if supported, access may be allowed after following the Authentication process. (Emulation package 20.3.0.3656) 

 

2.Problem Description

  1. (1) I can connect to the MCU normally when using the SD card image that comes with the development board.
     
    (2) The connection fails when I use the project compiled by myself, with my own tiboot3.bintispl.binu-boot.imgdtbImage and rootfs. My project only uses two CAN channels of the M-core.
 
I want to know the possible causes of this error and how to resolve it while ensuring that M-core debugging is not affected.
