MSP430F2132 又遇到下载问题,请教各位!

Other Parts Discussed in Thread: CC1101, MSP430F2132

请教一下各位大侠,
第一个问题:
MSP430F2132在不加外部电池,不加CC1101模块的情况下,仿真器内部供电,2线下载成功,但是一旦加载CC1101模块,电压下降到1.1V左右,测量无短路,照说模块功耗应该不至于这么大,而且上一版硬件电路已经测试OK,带模块下载无问题,更换多个正常CC1101模块,都是同样情况,而电路已经验证过,只是修改了GDO0/GDO2从P3口挪到P2口,没找到原因,
第二个问题:
在上述情况下,此时不外接CC1101模块,下载设置为外部供电,外接3.6V电池,测量电压正常,仍然无法正常下载,弹出致命错误,无法找到硬件 ,

请各位大侠支招啊!
