The parameter th(boot-mode) must account for a reset initiated from any of these sources.
See the Resets section of the System Control chapter in the TMS320F28P65x Real-Time Microcontrollers Technical Reference Manual.
Some reset sources are internally driven by the device. Some of these sources will drive XRSn low, use this to disable any other devices driving the boot pins. The SCCRESET and debugger reset sources do not drive XRSn; therefore, the pins used for boot mode should not be actively driven by other devices in the system. The boot configuration has a provision for changing the boot pins in OTP.
