用CCS Uniflash 给CC3200 下载bin 出现的问题,请问是怎么回事,怎样解决
CC3200 LaunchPad 剛開始使用時在 "Code Composer Studio 6.0.1" 與 "CCS UniFlash" 燒錄程序與flash都正常,但是使用幾次之後,目前都出現下載程序與燒錄Flash 時都是失敗的狀況,請問是哪出了問題?
绝对不是硬件连接问题,串口选择等问题,我认为是3200某个设计问题,希望ti的大神们使用3200的遇到过这种问题的工程师来解答一下,很很急

这是软件部分
这是软件设置
首先保证USB转串口FT部分是可以正常工作的,在下载过程中如果提示要进行Device reset时,需要手动进行复位,或者直接更新最新的Uniflash进行下载工作。
硬件板卡检查SOP的设置,将SOP设置为100,即SOP2上拉,其余两个保持低电平状态,此时CC3200启动后进入了UART0模式,进行程序的烧录工作。
