I have a J721E EVM development version, I created a project with CCS V12, when I use launch select configuration--LoadJSFile, the serial port prints an error message, except for C7x, other R5, C6x, and A72 can be connected. The error message is:
C71X_0: GEL: Error while executing OnTargetConnect(): Memory map prevented reading 0x0000000080680010
