I am using MK22FN1M0AVLH12 processor, copy the part code of the No-Block UART example of frdmk22f in V1.3 KSDK. The SW hold at send function, seems that send function can't find the correct ISR.
My question is,
- Why have the above issue? Should some place define interrupt vector?
- What evaluationd board is for MK22FN1M0AVLH12? TWR-K21F120M?
- I use wrong code? Not the code from frdmk22f?
