我做了一块板子,刚焊接回来时,用xds100V2仿真器连接不上TM4C129xnczad芯片,报错Error-2062:Unable to halt device.Reset the device,and retry the operation.If error persists,confirm configuration,power-cycle the board,and/or try more reliable JTAG setting.后来我把晶振烫掉,结果就能连接上芯片了,我又焊接了一个24MHz的晶振上去,能调试了,但今天烧了一个网口程序进去后,又连接不上仿真器了,出现上面同样的错误,我换晶振也没用。
