自己做的AM3352板子,将FT2232D集成到了板子上,但是连接不上CCS



如题:参考Beaglebone将USB转UART与JTAG集成到了单板上,通过FT_prog更改EEPROM,之后系统安装好了驱动,识别的情况如下图:

但是打开打开CCS建立连接的时候却连不上(CCS中仿真器选用的是XDS100V3),请帮看下是哪儿设置有问题,谢谢。

log如下:

This error is generated by TI's USCIF driver or utilities.

The value is '-151' (0xffffff69).
The title is 'SC_ERR_FTDI_OPEN'.

The explanation is:
One of the FTDI driver functions used during
the connect returned bad status or an error.
The cause may be one or more of: invalid XDS100 serial number,
blank XDS100 EEPROM, missing FTDI drivers, faulty USB cable.
Use the xds100serial command-line utility in the 'common/uscif'
folder to verify the XDS100 can be located.

[End: Texas Instruments XDS100v3 USB Debug Probe_0]

按照上面提示,使用自带的工具xds100serial 可以检测到这个口

USB芯片的eeprom中的寄存器配置如下:
