各位工程师们：
        大家好，我最近在用CC2538的芯片跑程序，用了TI的swrc271acc2538_foundation_firmware_1_0_1_0driverlibcc2538examplesstartup_filesstartup_ccs.c和cx2538xf53_ccs.cmd来建立项目，当我下载程序到CC2538一开始程序在不断运行，出现如下提示：

Cortex_M3_0: GEL Output:

1、我查了硬件电路，reset引脚上电时电压0.8V，仿真后下载程序进去再测reset引脚变成3.2V左右，拔出仿真器又变回0.8V。这是电压没有上拉还是给MCU拉低了电压导致复位？

2、出现这个错误的原因是什么？是内存映射出错还是硬件的问题

希望能够给我点提示和帮助，万分感谢。
