Hello, im using SPI and the fsl_dspi official driver, I noticed that when I used DSPI_MasterTransferBlocking function, i got an unhandled interrupt .
Here is my setup: KSDK_1.3.0 board: frdmk64f.
After the unhandled interrupt occurs, pls check the interrupt source index in the xpsr in debugger of the tools you are using, the bit0~8 of xpsr register represent the interrupt source index.
If the interrupt source index is 3(hard fault interrupt), it is a bit complicated, for example you use a peripheral whose clock is not enabled, or you access a memory which does not exist, all of the case can lead to hardware fault interrupt.
Anyway, i suggest you download SDK2.0 package from the link:
Hope it can help you
