We are Using MQX Rtos for our custom board based on MK60DN512ZLVQ10 series of Kinetis ARM Cortex-M MCUs. We have developed our application based on MQX 3.7 RTOS for our custom board and its working fine But we need to migrate from MQX3.7 to MQX We have ported from MQX3.7 to MQX and our application to MQX

The application developed on MQX 3.7 RTOS was working fine but we are placing problems with MQX

Our code is getting stuck in 'gpio_eport_irq' function. It keeps on getting the interrupts and it comes to 'gpio_eport_irq' and stays there.

The function is in 'io_gpio_kgpio.c' file. Ultimately the code goes to hang state.

Can you please help us in finding the cause of this behavior?
