ST-LINK V2+STVP 烧录程序时一直这个,还有如下:
> Programming OPTION BYTE area...
Error : Cannot communicate with the tool.
Wrong tool selection or check tool power supply or check that a previous session is closed.
Error : < OPTION BYTE programming failed.
每次要把目标车载机断电-关闭STVP-重新打开烧录程序-选OPTION BYTE ,要操作十几 二十次才才能烧录进去一次,:'(
而用STVD 连接另外一个学习板都没问题(偶尔会找不到tool,插拔下ST-LINK V2)
请高手指点怎么解决,谢谢! |
