TMDSDOCK28335: COM port is not detected in Device Manager

Mike,

Thanks for the follow up, take a look at this post: https://e2e.ti.com/support/tools/ccs/f/81/t/646137?CCS-TMS320F28377S-XDS100-V2-Does-Not-Show-Up-in-COM-Ports  If you scroll to the bottom the green/verified answer has a modified set of instructions to address this using this guide http://processors.wiki.ti.com/index.php/XDS100#Q:_How_can_I_use_the_XDS100v2.27s_second_port_as_a_serial_port_.28UART.29.3F 

Hi Matthew,

Thank you for the rely. I followed the steps. "Load VCP" was already checked even before. At the end I I was not able to get COM ports to appear. After some more playing around and trying different stuff, now I cannot see TI XDS100 Channel A or B under Universal Serial controllers menu. I can see Texas Instruments XDS100+RS232 v1.0.

There are several topics already with this issue on the forum (e.g. 1 and 2), but they do not provide solutions. I even came across some suggestions to delete usb.inf and drivers... did that help... Last option is to reinstall Windows.

If I try to manually update the drivers and point to C:\ti\controlSUITE\development_kits\~Utilities\XDS100 Drivers v1.0, the process is unsuccessful and I get the following message:

I have two controlCARDS and two docking stations and previously only one set worked, but now both do not work and show same when I plug them to USB port. I am not sure if buying a new set (controCARD and docking station) will help. If I scan with EEPROM Programmer MProg 3.5 I get:

Number Of Blank Devices = 0
Number Of Programmed Devices = 0

CCS 5.5 cannot connect and I cannot run <Test Connection>.

LD1 on Docking station R3 is ON and LD1 on controlCARD R2.2 is ON and LD2 and LD3 and flashing (i.e. executing all code that was there before all this happened).

MIke,
Yes, I would hold off buying more HW, I think this is tied to driver/FW as you have noted. I'm going to pull in some folks from the emulation team to see if we can get to the bottom of this.

Best,
Matthew

Hi Mike,
I have the setup as you - F28335 with docking station, connected to the USB XDS100v1. I reprogrammed the EEPROM as you did following the same instructions - it worked as expected. I'm not sure what the issue is on your end, likely something with your PC environment. Can you get everything recognized on another PC? Also, what is the host OS? Looks like Windows 10. What build?

Thanks

Mike,
Wanted to check back in, to see if you were able to look into the above questions from Ki-Soo.

Thanks,
Matthew
