Speed grade discrepancy on Zybo revB vs ZYBO_zynq_def.xml file.

[coloradosensors]

Hi,

 

I see in the ZYBO_zynq_def.xml file the following:

  <Projinfo Part="xc7z010clg400-2" DeviceSize="xc7z010" Package="clg400" Speed="-2" />

However, on my ZYBO board I see the chip in the attached JPG file.

 

(I attached the photo of the chip, because I had problems sharing a link. It says I can't use JPGs, is that right?)

 

I think I have a speed grade 1 chip, but the ZYBO_zynq_def.xml file indicates speed grade 2.

 

This appears to be a mis-match. Is the file correct? What am I missing here.

 

Does this file run OK on my ZYBO revB board? Thanks for your patience!

 

Cheers,

David

Hi David,

 

You are correct in seeing that the SoC on your board is speed grade 1. After talking with support, it seems that the .xml file was for the revA prototypes which did have the speed grade 2 chip, so they will get this file corrected when they get the opportunity.

 

The file itself will work just fine with the speed grade 1 chip (hence why it slipped through), but we'll get this updated in the near future so that it matches.

 

I personally see thumbnail you attached; I know some links have a weird file extension at the end of it which the forum will reject, so I recommend if you ever need a higher resolution photo uploaded to forum to use our Gallery.

 

Thanks,
