Other Parts Discussed in Thread: MSP430FR4133,
i am having the "debug interface secured" problem also. I changed the mcu its solved. Then it happened to new mcu during debugging.
this code may be the problem?
extern uint16_t *AC_infrared_buffer_ptr = (uint16_t *)0xD000;
i didnt have that problem before this i think.
i cant erase the code by msp flasher.
