关于2640烧录程序的问题。

我手上的4X4封装的芯片，使用IAR可以仿真，使用IAR下载后复位可以正常使用。

但是使用TI的SmartRF下载器下载后运行不了，打开数据校验，单独下载APP和STACK的时候，校验出错，信息为：

问别人借了同样封装的芯片未发现这样的问题，并且我手上的10片都会这样。请技术员不要单纯的让我去找供应商或者换官方指定供应商，我想找到原因，谢谢。

weihao，

你的smartRF Programmer是最新的吗？TI官网可以搜索下载。

你的4x4是哪个PG版本的？这个在smartRF Programmer中可以看到，最新的是PG2.3， 如果是PG2.1或者之前的，那不是量产版本的芯片。

我也遇到同样问题，校验失败。使用的4*4 CC2640芯片，在smartRF Programmer2显示的PG是unknown，烧写过程中PG会变成0.0。

请问这是什么原因，芯片有问题？验证两片都是这样的
