前边都正常执行，但是执行到while（1）单步执行时就会遇到
CORTEX_M3_0: Can't Run Target CPU: (Error -1268 @ 0x90001) Device is locked up in Hard Fault or in NMI. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.762.0)
用的是LM3S9B92，编译环境是CCSV5.2.1 这个问题困扰好几天了，麻烦指导
