Errors building Clocked Video Output

--- Quote Start ---

I added a Clocked Video output to a design and feed it with a scatter-gather DMA. There are two Avalon ST adapters in the path to make it work.

I'm getting a bunch of errors like this:

"Error: IP Generator Error: Unable to set generic "USE_EMBEDDED_SYNCS" on entity "alt_vip_itc"- the parameter cannot be found on the entity"

I'm attaching a screenshot of the Quartus errors below.

The design is based on the Cyclone III starter kit example from the nioswiki. It contains a CPU, SSRAM, SDRAM, flash and the SGDMA/CVO thing I added, no other video blocks.

Thanks,

Andrew

Hi Andrew,

I suppose, the query in nios forum was posted by u about this issue. As i mentioned there, you will need to write a custom component, which will convert avalon streaming protocol(output of SGDMA) to avalon ST video prototcol(input of clocked video output).

without that, your design will not give correct functionality, even if you manage to compile it without error.

the avalon ST adapters are just for avalon streaming protocol and they will not solve the problem of avalon ST video protocol.

i suppose, these errors will be resolved once you put the custom component in your sopc builder.

good luck!
