Karl,

We are seeing this problem from a few customers and it appears to be related to the pc. Can you send me the type of pc and the operating system you are using. Have you tried a different pc? We are currently trying to resolve this issue and any information you can provide will help us.

Regards,

Jim

It is a Dell tower T3400, the OS is Windows XP Professional SP3. I can try a different computer, I have a T3500 with Windows 7 as well and can try it.

Thanks,

Karl

Windows 7 also did not work.

Hi,

We are looking into this, but there are a couple of easy things to ask first, just in case it is one of these things.

Is the power to the TSW1400 on?  There is a slide switch next to the 6V power input jack.  The first time I installed the TSW1400 I did not think to look at the power switch because the USB port is powered off the USB cable and so the board looks to be 'live' to the GUI even if the FPGA is off.  But the cooling fan on the FPGA was not running, which was my only visual cue that the power was off.  And having the power off to the FPGA gives the same firmware download error.

Is the USB port being used a USB 2.0 port?  I don't think we support USB 3.0 ports yet, and I'm not sure about USB 1.0 ports.

I am having the same problem Karl reported but I am trying to connect to a ADS4149 board.  Do you have any suggestions?

Cheers,

Kyle

Kyle,

Can you provide more info on what your problem is?

1. Does your TSW1400 work with other evm's?

2. Can you connect to the board with the GUI?

3. What version of GUI are you using?

4. What OS are you using?

5. Is the 5V led on after turning on the main power switch?

6. If you get to the point where you start loading firmware and it fails, what error message does the GUI report?

7.Have you tried a different computer? If so, did it have a different OS?

Regards,

Jim

Kyle,

If you want to attempt to trouble shoot the board, on the top side of the board near one of the corners of the FPGA are 8 resistors that could possibly cause this problem. Make sure R61, R62, R63, R64, R149, R150, R151, and R152 are all installed and read 0 Ohms across each one. If you want to send the board back for a replacement, please send your board to the following address:

Jim Seton

Texas Instruments

12500 TI BLVD

Dallas, TX 75243

M/S 8755

FedEx account #106695628

They all check out at ~.2 Ohms.

Kyle,

Send the board back and we will get another one to you ASAP.

Jim

Hi Jim,

I am the purchasing representative for UW Madison who purchased this eval board.  Is the FedEx account number the RMA number so that we can return this board for replacement? If not, could you please provide an RMA number for shipment and replacement of this part? 

Debbie,

This number should allow Fed Ex to bill TI for the shipment. I do not know what a RMA number is.

Regards,

Jim

Hi Jim,

Kyle Jero who has the part for return tried to call FedEx using your account number and they indicated that without a printed label they are unable to help us return this part.

I believe that you will have to contact FedEx and explain the situation as it is your account number.  Then I think they issue you an RMA (return merchandise authorization) number and send (probably email) a label which you can forward to us to return the part.

Please let me know what you are able to find out from them.  We are unable to return this part without a label currently.

Thank you,

Debbie Sewell

Debbie,

You can call TI product support center at 512-434-1560 to get an RMA number for return merchandise. Let me know if this helps.

Regards,

Jim
