Hello everyone. I’m trying to use a driver that uses spi with my RA6M3 board. But I ran into a problem that I had not encountered ahead. The NMI interrupt goes into an infinite loop and doesn’t live. I do not know much about NMI so I do not know what to do. The NMI pin on the RA6M3 board is P200. P200 isn’t enabled but never gets stuck in NMI masking function in the spi_transmit process. And it can not exit NMI_Handler.
