How to determine origin of Default ISR error

Hey there,

in my project I am using the UART capability of the K64F board. I didn't use it for a couple of days, and now when I restart it the program stalls it stalls. I have reduced my program to the following line (plus a win the main while loop for example:

    UART_DRV_SendData(UART_INSTANCE_1, test, 4u);  

 

 

If I go into the debugger and press pause, it shows me line 349 in the startup_MK64F12.S file, which has something to do with the default ISR.

 

Whitch includes, project settings and setup code in the program should I check to fix that?

The only thing I changed is the debugger, because somehow the board had become unresponsive and I had to repair it by dropping a PEMicro .bin file into the bootloader.

 

Thanks for any help and information,

Michael
