Thank You for assistance..

Effectively the driver I use is already coming from there. I tried the normal things, reinstall and restart the machine, it does not work the error is always there. I tried for similar problem in this community but it does not look a common problem. So what to do???

I am running a Windows 7 and the guidelines suggest something for Windows 8, the problem I see should not be there...

I tried anyway to look for a driver signature for this Windows but I do not find.

I hope there is a solution

Thank You

Pietro

Hi Pietro,

Thanks for your updated information.

I have a question, if you don't run USB code, just run the helloword, whether the opensda COM can work on your side? J26 virtual port, can you find the com port in the win7, I also use the win7, it works Ok.

So, please try the opensda virtual com port at first.

Any updated information, please kindly let me know!

Have a great day,
Kerry

Hei Mark

Thank You for the references. I am following the source of information.

The SDA on my FRDM board is not working, I always use the JTAG, and I am happy in this way. One time I put the header connector on the SDA and I deleted the SDA software on the other uP. I do not depend on the SDA so for me it is not important. I want to use the other USB port linked to the main processor and test the new serial port. it should not be a problem. I suppose.

I have another thread for restoring the SDA which is better to have working... that's another subject...

Thank You

Pietro

Hei Mark

All of the information are around the uTasker. And I don t see any source code, just binary files.. I need a project to use and the driver to start..
I have now not ant SDA to try and I try to solve the problem on another thread...

I wander if I am the only one with the CDC driver not starting...

So this computer has some crap...

Thank You

Pietro

Pietro

The project is available as open source on Git hub (links at the bottom of the post) in case you want to build and load instead of use a pre-built binary.
