I’m getting the above message when I try to unpack ospi.tar.gz ib the pi directory like it says in the README found on Github. I thought maybe it was just my inexperience with linux, so I attempted to unpack it with Winrar on my windows machine but it tells me that the archive appears corrupt. I have DL’d the package multiple times from both Ray and Dan’s github but I’m getting nowhere fast. Please help a n00b out and point me in the right direction! Thanks!
