Can't load USB driver for TMDSEVM6678L Evaluation Module

Other Parts Discussed in Thread: TMS320C6678

We recently purchased a TI TMDSEVM6678L Evaluation Module. I have been unable to install the software on my Windows 7 PC. I followed the "Quick Start Guide". My recollection when I first plugged it into my PC USB port and ran DPinst on the CD.  was that a message popped up that it couldn't find the driver or some such thing. Anyway, now when I bring up "Devices and Printers" on my PC I see a "Texas Instruments XDS100-RS232 V1.0" with a yellow caution triangle. In the area at the bottom of this display, it indicates the Model "Texas Instruments XDS100-RS232 V1.0", Category "UnKnown", Status "Needs Troubleshooting". Although I have it connected to the network, I'm pretty sure it's not getting access because our corporate network requires a device to be registered before access is granted. To register this device I need the MAC address. I don't know how to determine the MAC address to get it registered with our IT department.

    Hi,

    Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues). Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics (e2e.ti.com).

    A serial port is provided for UART communication by TMS320C6678. This serial port can be accessed either through USB connector (USB1) or through 3‐pin (Tx, Rx and Gnd) serial port header (COM1). The selection can be made through UART Route Select shunt‐post COM_SEL1 as follows:

    1. UART over mini‐USB Connector ‐ Shunts installed over COM_SEL1.3‐ COM_SEL1.1 and COM_SEL1.4 ‐ COM_SEL1.2 (Default)

    2. UART over 3‐Pin Header (COM1) ‐ Shunts installed over COM_SEL1.3‐ COM_SEL1.5 and COM_SEL1.4 –COM_SEL1.6

    For more information refer section 2.14 UART Interface on C6678 Technical reference manual. 

    Refer keystone lab manual and TMDXEVM6678L EVM Hardware Setup, it should help you for run the MCSDK examples on EVM and boot mode selection.

    Please download the latest MCSDK for Keystone I devices(C6657/70/78) and the follow user guide here.

    Thanks,
