I am developing on a Kinetis K60 and on MQX3.8 I was successfully using _cortex_int_init() to call my ISR handler on a port edge interrupt. Now that I have to use MQX4, it doesn't compile as there's no definition in <cortex.h>. I tried _bsp_int_init() but that gets translated to _nvic_int_init(), which the compiler can find in <nvic.h> but the linker can't! All I can find in <cortex.h> is _psp_int_init(), but I've no idea if that's equivalent or what the arguements are?
Can anyone help?
