I can’t connect to the JTAG USB emulator of my beaglebone Rev4.
Here is the message when testing connection:
[Start]
Execute the command:
%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -F inform,logfile=yes -S pathlength -S integrity
[Result]
-----[Print the board config pathname(s)]------------------------------------

-----[Print the reset-command software log-file]-----------------------------
This utility has selected a 100- or 510-class product.
This utility will load the adapter ‘libjioserdesusb.so’.
An error occurred while soft opening the controller.
-----[An error has occurred and this utility has aborted]--------------------
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 one or more of: invalid emulator serial number,
blank emulator EEPROM, missing FTDI drivers, faulty USB cable.
Use the xds100serial command-line utility in the ‘common/uscif’
folder to verify the emulator can be located.
[End]
Notice that my beaglebone is correctly started with the BSP and the two FTD1 port are visible as ttyUSB0 and ttyUSB1 and i use ttyUSB1 for the terminal emulation on the board.
Notice also that i’m running ubuntu 11.04 in a virtual box on MacOSx.
Last notice the result of the required test command:
sudo ./xds100serial
