CC3220SF LaunchPad返回Error -2131@0x0,如何解决?
我使用CC3220SF launchPad,刚刚开始,使用demo学习中。build通过,但debug时出现如提示(Unable to access device register),断电重启、reset均无效果,不知道什么原因,怎么解决? 谢谢。

参考这个,另外你驱动安装正确吗?是第一次就这样,还是之前是好的,突然这样了?这个你要说明,因为有可能是第一次正常,然后不正常,这种是固件搞丢了。
驱动应该是没错,设备管理里面显示有XDS110的两个com端口。SDK、CCS等都是刚刚装上,按着start_guide一步步进行的,第一次就出现这个情况,还在学习中....
换了一台PC,也是一样....
默认状态下CC3220SF Launchpad 为Production 模式,需要连接Uniflash将Production mode修改为Debug模式,然后才可以通过Jatg进行程序的仿真下载。
谢谢! 怎么修改呢? 没有看到相关介绍。
直接使用CC3220连接到Uniflash.
Production模式修改为Debug模式直接用UART连接到Uniflash进行新建一个工程,将其模式修改为Debug即可,参考应用手册SWRU469
