求救:C6678 EVM是不是被烧坏了



我用emif的扩展口来读取ad采集到的数据,本想将ad采集到的16位数据接到emif的data口上,但是不小心插到了旁边的emif 地址线上,ad芯片数字部分的电源是3.3v,之后我用ccs连接板子,发现链接不上,报错如下:

Error connecting to the target:
(Error -2131 @ 0x0)
Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 5.1.232.0)

很担心,是不是我的开发板被烧坏了。我测了一下,ad板子的数据线电压,因为我没有在ad上加输入信号,所以数据线基本在0v左右,只有最低bit有抖动(0~3.3v)
