Simple DSD modulator for DSC2

[rfbrw]

For programming the device or the config prom VBox is not necessary. If you already have the .bit file, then the Xilinx Lab Tools is all you need.

I'm at this point.

You have to create mcs file from your bit file: double-click "Create PROM File" and follow the steps you can see in the pictures below.
Check your flash memory chip on the modulator PCB, is it M25P80? I assume it is.
When you will have mcs file, right-click on the SPI/BPI square in the "Boundary Scan" tab and attach the SPI file you created (it will ask to choose the right model, so you should pick M25P80 from the drop-down list) and "Program" it - it will take a while.
Check this document from page 6.
Or you can check all steps from this document, starting at page 14.

Thanks Torp, when I press OK button to add device the programm goes out and stops working

"Is it M25P80?"

Impossible to read....

Looks like maybe you didn't have the FPGA connected? Did it at least create the .mcs file?

Using a magnifying glass and a flashlight held at an shallow angle to the top of the eeprom?

 

[merlin el mago]

Tried also without success.

How to check it?

Red LED at pcm2dsd board is lighting. Green LED Status at Platform Xilinx is also lighting.

In the pic below, the upper right hand corner shows where the .mcs file should be saved at, and what its name should be (steps 6 and 7).
Explore to that directory location and see if the .mcs file is there.

When the FPGA is connected it will be shown in the Impact window something like in the pic below. The eeprom (green with the word FLASH when this pic was taken) may or may not be shown.

I didn't create the .mcs file.

In the upper right hand corner of the Impact window you can collapse the window, or reduce the size of the window, or close the window. Either collapse it or reduce its size. That should expose the Virtual Box linux desktop. There should be a file folder there. You need to look in linux file directories, not in windows directories.

 

[merlin el mago]

When I collapse the Impact window shows attached pic.

 

[Markw4]

Can you collapse or reduce the size of that window? You are still not at the linux desktop.

You could also try CTRL+ALT+D hotkey combination which might take you to the linux desktop. Depends.

 

[merlin el mago]

Collapsed or reduced only this 2 windows,

 

[Markw4]

What happens when you first open Virtual box and start the linux session, do you ever see the linux desktop? Otherwise how do you start Impact? Don't you have to click on it to open it?

 

[merlin el mago]

I open Impact from here

 

[Markw4]

So, you're not running Virtual Box? You're running Lab Tools from Windows?

When you try to create the mcs file, what output directory did you select in Step 7?
