extern crate cortex_m;
extern crate cortex_m_rt;
// extern crate panic_abort;
extern crate panic_semihosting; // reports panic messages to the host stderr using semihosting
 
use cortex_m::asm;
 
fn main() {
    panic!("Oops");
}
 
// As we are not using interrupts, we just register a dummy catch all handler

extern "C" fn default_handler() {
    asm::bkpt();
