My homemade 1843 development board encountered a problem, I flash the xwr18xx_mrr_demo.bin of TI's official website to my board, and found that the WARM_RESET indicator kept flashing after power-on, but as the temperature rose, the board would return to normal work, during which I did not do any other operations, I tried two boards appeared this phenomenon. If the heat gun is used to raise the temperature of the board, the board will quickly return to normal. What is the problem with this?
