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.
Thank You
Hello, What's the value of the NMISR register when the NMI handler is called? The value of the register gives some data about the cause of the NMI interrupt. Also at what point inside the 'spi_transmit' does the NMI occur? Regards Alex Thomas
