ADV7622 drivers

Hi Hank,

Customer will need to sign an SLA. Have their Sales/TSM contact me to get that started.

Thanks,
Dave

Hi Hank,

Is the customer looking for the Windows driver to interface with the Cypress USB-to-I2C on the evaluation board?

Or are they looking for the software driver which runs on the ARM processor on the evaluation board and configures the ADV7622?

These are very different things.

The customer says he needs both.

With regards to the source code for the software driver which runs on the evaluation board's ARM processor and dynamically controls the ADV7622, the customer will need to work with ADI sales to sign an SLA, as Dave mentioned above.

With regards to the Windows driver to interface with the Cypress USB-to-I2C, I believe this should load automatically when the customers connects a powered evaluation board to Windows via USB. What operating system is the customer using? Windows 7 32-bit or Windows 7 64-bit?

Hello Matt,

I am confirming the OS.

What the customer is asking for is "I2C drivers to allow the DVP application to go in and read/write to the registers". Does that require the SLA or is that something that should happen when the evaluation board is connected to the PC?

I am assuming the SLA. I have contacted my local ADI sales for the SLA process, but this is still open after several weeks. How do we move this forward?

Thanks,
Chris

From my customer:

I’m running Windows 7 on the machine on which I’m trying to communicate with the eval board. However, our main software guy does his development in, and all of our products run Linux.

Hi Chris,

For the EVAL-ADV7622EBZ register control software, we only support Windows 7 32-bit and 64-bit.

When you connect the evaluation board's USB port to Windows 7 32-bit/64-bit, the USB drivers are automatically installed.

Hello Matt,

Here is an update from my customer on this issue. Does he need the Rev D config file? If so, where do we locate it? Thanks.

I retried my prior procedure on both a winXP and win7 device with no luck. However, when I run the "scan for devices” inside the eval software I consistently get a list of 20+ registers, which leads me to believe that Matt P in the forum is indeed correct and that the issue was not missing drivers, but instead the wrong configuration file:

I realized that I have been loading the ADV7623 Rev. C XML config file, and the board is Rev D.  — I looked at the FTP address (ftp.analog.com) for a Rev. D XML file but it seems there has been some restructuring and was unable to find it by hand. I’m running a comprehensive search now and will let you know if I find it.

The config file that I had been using was called “ADV7623C.XML", so I would assume the one I need is called “ADV7623D.XML”. If you can locate that file, I believe this should let me read/write to registers. I will continue to look as well.

Thanks,
Chris 

BTW - the customer is using Windows 7 64-bit.

Can we get the ADV7623D.XML?

Thanks.

Hi Chris,

The C in ADV7623C.XML stands for customer. That's the correct file. I got mixed up on that also in the past.

So did the customer follow the instructions on page 7 of ADV7622_23_EvalBrdUsrGuide_RevA_241112.pdf about adding a new board to the application? Does ADV7623 show up under RX? Please have the customer post some screen shots of what he's seeing.
