系统：
和：
[dependencies]
cortex-m = "0.6.0"
cortex-m-rt = "0.6.10"
cortex-m-semihosting = "0.3.3"
panic-halt = "0.2.0"
说明
我遵循了https://rust-embedded.github.io/book/start/hardware.html
中描述的步骤我得到了以下内容：

555 atomic::compiler_fence(Ordering::SeqCst);
进一步的调试显示，在lib.rs中执行这些行时会发生硬故障
// Initialize RAM
r0::zero_bss(&mut __sbss, &mut __ebss);
r0::init_data(&mut __sdata, &mut __edata, &__sidata);
我该怎么办？
