CC3200 自己画的板子无法使用uniflash下载，求助！

请帮我看一下 现在自己画的板子可以进行debug 调试，引出的LED灯可以进行控制亮灭，但是无法使用uniflash 下载程序，串口使用的uart0 ，sop 2 接高电平，低电平都试过，复位信号直接在lanchpad 读取，但是依旧无法下载程序，遇到瓶颈了 ，请问还有什么我没有注意到的问题么？

下面是更为详细的输出信息，请TI员工和做过的大神看看，指出一下问题！

唉，问题都解决掉了，还没有回帖的~

问题已解决！

楼主的问题怎么解决的？我也快调试自己作的板子了。

请参考此帖：https://e2e.ti.com/support/wireless_connectivity/f/968/p/385212/1358678

我现在也在做自己的板子，能留下个联系方式，请教你吗？

楼主是怎么解决的？我也遇到这个问题了，现在不知如何是好

请教，同遇到问题uniflash不能下载，请问怎么解决的

多年的老帖了，现在已经都不用3200了，不知道现在3200还这么火，如果不能下载看连线是否都正确，然后如果确定走线都对的话，把和电源相关的电容都换成更大尺寸的电容，就是指的TI开发板那几个和电源相关的大电容，如果还不行那就需要考虑走线了，两层板设计我都失败了，所以四层板设计应该严格按照官方推荐，GND层有两个独立的电源回路，你可以看一下，如果都注意了，应该就没什么问题了

恩恩，非常感谢你的帮助，我确定连线都正确，板子也是根据ti推荐电路来设计的，可能pcb设计上有些问题吧，一直不能下载，我新下载了个uniflash试了下，也没有错误显示，也不能下载，懵了……我去提问看看吧，再次感谢你的帮助
