IDE: CCS V5.5

平台： 英蓓特  BeagleBone Black (B4)

利用CCS的TI Resource Explorer ，选择BeagleBone Black 下Generic Examples中的Hello World.

Step 3:        Debugger Configuration        
Connection: Texas Instruments XDS100v2 USB Emulator
Click on the link above to change the device connection. Additionally, this option is also available in the project properties.
最后Step 4Debug the imported project总是出现

Error connecting to the target:

-----[Print the reset-command software log-file]-----------------------------

This utility has selected a 100- or 510-class product.
This utility will load the adapter 'jioserdesusb.dll'.
The library build date was 'Aug 20 2013'.
The library build time was '22:56:19'.
The library package version is '5.1.232.0'.
The library component version is '35.34.40.0'.
The controller does not use a programmable FPGA.
The controller has a version number of '4' (0x00000004).
The controller has an insertion length of '0' (0x00000000).
This utility will attempt to reset the controller.
This utility has successfully reset the controller.

-----[Print the reset-command hardware log-file]-----------------------------

The scan-path will be reset by toggling the JTAG TRST signal.
The controller is the FTDI FT2232 with USB interface.
The link from controller to target is direct (without cable).
The software is configured for FTDI FT2232 features.
The controller cannot monitor the value on the EMU[0] pin.
The controller cannot monitor the value on the EMU[1] pin.
The controller cannot control the timing on output pins.
The controller cannot control the timing on input pins.
The scan-path link-delay has been set to exactly '0' (0x0000).

-----[The log-file for the JTAG TCLK output generated from the PLL]----------

There is no hardware for programming the JTAG TCLK frequency.

-----[Measure the source and frequency of the final JTAG TCLKR input]--------

There is no hardware for measuring the JTAG TCLK frequency.

-----[Perform the standard path-length test on the JTAG IR and DR]-----------

This path-length test uses blocks of 512 32-bit words.

The test for the JTAG IR instruction path-length succeeded.
The JTAG IR instruction path-length is 6 bits.

The test for the JTAG DR bypass path-length succeeded.
The JTAG DR bypass path-length is 1 bits.

-----[Perform the Integrity scan-test on the JTAG IR]------------------------

This test will use blocks of 512 32-bit words.
This test will be applied just once.

Do a test using 0xFFFFFFFF.

请问是什么原因导致无法调试的呢？

尝试更换不同的gel,最后总是Load Failed. 什么原因呢？

还是有什么地方操作不正确？

我是用了StarterWare，也不行。
