TUSB3410 intermittent communication

Hello,

You can download our latest VCP driver from this FTP pickup site:

ftp://pickup@ftppickup.ti.com/pub/share/kooheph

User Name = pickup , Password = piurh!

This driver version is v3.2 (6.5.9017.0), and has some fixes related to open/close COM port issues shown in some other customer’s SW apps.

I suggest trying this new driver and installing it on a fresh OS installation. This one is compatible with XP/Vista/Win7. Also, this is a license wrapper that will install the driver’s installer on a default location or any other path you may choose.

Thanks and Best Regards,

Ismael

Ismael,

Good day.  I have tried to access the ftp site from here at work and also at home.  In all cases, I have not been able to access the ftp site.  I get a message that says that I do not permission to access the site.  Please also know that the zip file that is downloaded via the conventional file download only contains a text file.  The executable is not in the zip file.  I do not know if it is blocked by something or what.  If there are no other download options, would it be possible to burn a copy to a CD or something and mail it to us?

Thanks,

Dave

Dave,

I suggest doing a second attempt... The full FTP info is as follows:

-------

The ftp pickup directory 'kooheph' was created on 11/10/2009 10:30:01.

The files from the dropoff area have been moved to the pickup directory and are available for 7 days.

To retrieve the files from the pickup directory:

1. Open an ftp session to ftppickup.ti.com.

ftp ftppickup.ti.com

2. Login with the userid 'pickup'.

Name: pickup

3. Enter the password.

Password: piurh!

4. Change directories to the pickup directory.

ftp> cd /pub/share/kooheph

Note: If you are using a graphical ftp client, you will not

see the hidden pickup directory name kooheph appear

in the file list. You will need to use a manual

'Change Directory' or 'CD' command to change into the

dropoff directory.

5. Set the file transfer mode to ascii or binary as necessary.

ftp> bin

6. Transfer the file.

ftp> get <file>

7. End the ftp session.

ftp> quit

The files can also be retrieved with the url:

Regarding the download issue from our website, our website team is working on it, so I hope that tomorrow you'll be able to download it from our website w/o troubles.

Best Regards,

Ismael

Isamel,

I do appreciate your itme and patience on this.  I am getting the above result.  This is basically the same result I was getting yesterday.  So, if you feel the website will be good to go in a day or two, I can wait and try that.  Please let me know if there is anything else that I can attempt.

Thanks,

Dave

Hi Guys,

I can not download the file either !

Is any alternative way existing to get this file(rather  than download or ftp )?

Ismael, Please let me know that is possible to get CD/DVD from TI ? I can provide UPS account for RED shipment .

Thanks &Regards

Ashkan

Dan,

Thanks for quick respond,I did download it.

Have a great time

cheer

Ashkan

All,

Now I have a technical  problem !

After I execute the driver to ver3.2, I could not connect to USB and my application can not  detect and send the command to the device?

Should I do any especial processes or do I need to change my code for communication ? is there any different declaration?

Thanks in advance.

Ashkan

I don't know if this is important, but the file inside the zip file is just called "setup.exe", rather than "TUSBWINVCP_WDF-Single_Driver_v3-2.exe" as the download page claims.

Creighton,

When you do install ,name will change to appropriate name .

Thanks for suggestion.

Actually  command can not open the port ! here is portion of the code:

"

Try

 If obj.Open()

Then

Hello Ashkan,

I suggest to double-check if the VCP driver has been updated at device manager. Latest driver is version 6.5.9017.0 (we called it v3.2 as a major version). In case it has been updated and a driver failure is suspected, then could you please share your SW app with me? Please let me know if there's a link to obtain your SW app and if it is compatible to any TUSB3410 device (since I don't have your 3410 implementation), I'll like to use one of our EVM for testing your app.

Best,

Ismael

Good morning Ismael,

I would like to say especial thanks to you for follow up my issue.

The driver properties tab shows Version  6.5.9017.0  and I will get confirmation from my manger to send the whole or portion of the code to you .

Please let me know what exactly you need?

-executable application ? or

- source code of application (whole or related portion ) ? 

-firmware code (whole or related portion ) ?

Thanks&Regards

Hello Ashkan,

Please share your EXE app if possible (you can maybe attach it here on your post...), I'll like to test it along with this scenario:

PC <-> Your SW app <-> Win VCP driver <-> TUSB3410 Eval board

Please let me know if the issue can be seen with the scenario above, or if any special HW is needed (or VID/PID info in order to get your app working?)...

Thanks,

Ismael

Hi Ismael,

Our application Load from E2PROM via I2C,Attached is our application.

We use own hardware ,But I think you can use Eval board as a test (data will be garbage).

I generate .bin file with .cfg and .BAT, put the hex data in appropriate portion of E2PROM  and also I take out the .i51 command from .inf .

My problem is :during install driver still asking about .i51  !!!  Any suggestion ?!

Thanks & Regards

Hi Ashkan,

Could you please share you INF just to take a look at it? I want to double-check it, maybe there are a few *.i51 calls still there... please ensure that all of those calls are commented or removed, so you can avoid the install wizard asking for the FW, since it's already burned in your EEPROM. am I correct?

Regards,

Ismael

Ismael,

Thanks for suggestion ,.inf is attached.

I did check twice ,but As you said I will check again.

Yes, You are absolutely right  and device manager will detect the USB chip without install wizard,but can not talk to it .

I did step throw the code ,Detection is fine ,just it has problem to communicate (in method ,open and close object doesn't work !)

Best regards and Thanks for quick respond

Ashkan,

I checked your INF and looks correct to me... Although I didn't see your VID/PID info. Do you have one?

Also, is the BIN file you are burning in the EEPROM using our default umpe3410.i51 FW? or is it a customized one?

Thanks,

Ismael

Ismael,

For now that we are still developing the product and that is why we do not have our own PID/VID.

I watched the Tip video and the guy mentioned about reseller rights ,How is that and what we should do for future to have reseller rights ?

Regard the .bin file ,I did customize it and address 0x0000 to0x0083 is for USB .bin considered.

Thanks & Regards

Ashkan 

Ashkan,

Ok, I'll like to take a look into your CFG file and FW file you used to generate the BIN file which will be burned in the serial EEPROM (if possible, it will be useful the BIN file itself, but a rather prefer the CFG and FW files...). It will help a lot to address the issue you are seeing at your end.

Thanks,

Ismael

Ismael,

I did not modify any of original files that TI provided for us.

I generate the .Bin file based on your file with no modification(Only I did change to small name of the  .CFG file).

Thanks & Regards

Ashkan

Ashkan,

I have some questions in order to clarify some points:

Could you please share the CFG file?

Are you combining it with our umpe3410.i51 FW file?

Which tool are you using to burn the generated BIN file into the EEPROM?

Thanks,

Ismael

Ashkan,

Ok, I got both the CFG and BIN files...

I'll generate a new BIN file using our default CFG and header generator utility... then I'll burn the BIN using our EEPROM Burner Application (since I don't have your EEPROM programmer...), but please guide me in how to use your SW app... if possible, a document showing a step-by-step scenario on which the TUSB3410 VCP driver shows the issue you are seeing at your end will be very very helpful...

Thanks and Regards,

Ismael
