We are using ZephrOS V2.1 on IMXRT1062. In some condition (uncertain which for now), the MCU end-up in the NMI handler that is just a infinite loop in ZephyrOS, freezing our application.
I've understand that on ARM Cortex-M, use of the NMI interrupt is SoC/MCU dependent. Reading all possible NXP documentation, I understand that the NMI input can be routed to the WAKEUP pin. Are they other use of the NMI in the SoC IP ? Any future documentation ? What else could trigger the NMI interrupt ?
