各位工程师：
大家好。我最近在用CC2538，内核也是M3.加载程序总是提示不断重置。提示如下：
Cortex_M3_0: Trouble Halting Target CPU: (Error -1266 @ 0x0) Device is held in reset. Take the device out of reset, and retry the operation. (Emulation package 5.1.402.0)
Cortex_M3_0: GEL: Error while executing WaitForReset(): Could not read 0x20003004: Execution state prevented access at isAtResetIsr=*((int *) 0x20003004) [cc2538.gel:91] at WaitForReset() .
Cortex_M3_0: Trouble Halting Target CPU: (Error -1266 @ 0x0) Device is held in reset. Take the device out of reset, and retry the operation. (Emulation package 5.1.402.0)
Cortex_M3_0: JTAG Communication Error: (Error -1170 @ 0x0) Unable to access the DAP. 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 5.1.402.0)
Cortex_M3_0: Failed to remove the debug state from the target before disconnecting. There may still be breakpoint op-codes embedded in program memory. It is recommended that you reset the emulator before you connect and reload your program before you continue debugging
对M3的启动过程还不是很了解，还希望大家能够指点一下。
谢谢
