CC2642R1F ccs下载程序报错

Other Parts Discussed in Thread: UNIFLASH, LAUNCHXL-CC26X2R1, LAUNCHXL-CC2640R2

现在遇到一个问题,之前买的CC2460R2开发套件由于不能进行多设备定位,故买了几片2642R1F的芯片替换开发板上的2640R2F芯片,当然晶振从24MHz换为了48MHz。现在遇到个问题,下载的时候报错,不能下载。ccs版本为最新的10.1版本。

  然后我用用smartRF Flash Programmer 2 Ver.1.8.1版本进行flash烧录也提示失败。擦除flash是ok的,就是烧录程序的时候报错:Failed to read last page.

具体报错如下:
