Hi,

I had a general question on PYNQ packages. I don’t understand the purpose for some of them. Is there some where in the documentation that explains what the purpose of each package is.

I included the Ethernet package in my spec file when building the PYNQ image since I wanted to utilize ethernet to connect the board to the computer. However, I didn’t include packages like pynq in the spec file, since I didn’t know what the purpose of it was. Appreciate if you could give me guidance on what the PYNQ packages in the sdbuild folder are! Thank you!
