1. Use interrupt config header file and interrupt cfg.c file in example_config
2. build and run fls_app on mcu2_1 core
3. When app is doing interrupt configuring, it will receive "Error in SciClient Interrupt Params Configuration!!!" Please see log file
4. Then app gets stuck when doing read or write commands that's done by interrupt

only j721e fls_app (interrupt) works on mcu2_1
