Same issues here. I thought it might be because I had installed the drivers that came with 1.9.9beta (which I started with) and also the ones with 1.9.8.10 but it looks like it may be a common problem.

I can also download the bitstream to the TN9K: https://raw.githubusercontent.com/dimitrit/nabu-howto/mai...

It looks like I've managed to program my shiny new TN9K: https://raw.githubusercontent.com/dimitrit/nabu-howto/main/images/tn9k_test-image.jpg However, when I try to (re)synthesize the project files I get the following error: ERROR (IF0008) : The number(131072) of DFF used to infer "ram" e...

This looks great, thank you for sharing!
