Chisel HDL example applications

Hey! 👋

My name is Carlos Eduardo, I'm an open source enthusiast living in São Paulo/Brazil. I'm interested in all things about technology, from low level hardware, FPGAs and infrastructure to software development in a multitude of languages like Golang, Python, Scala, Erlang and many more.

I work at Red Hat as a Cloud Architect and I'm a RISC-V Ambassador. Write about cloud computing, hardware, FPGAs and development at carlosedp.com.

chisel-playground's Issues

SymbiFlow Installation for OSS Synthesis

How did you setup the SymbiFlow tools to run the "arty7-35t-oss" target? I tried setting them up with the example in the symbiflow-examples repo, but when I run conda, I get an error when trying to import fusesoc. If I can get the tools working, I can add support for a "nexys4ddr-oss" target.

[Blinky] Strange Error while adding OrangeCrab support

While attempting to add support for the orangecrab FPGA board, I ran into a strange error:

Do you know what could be causing this? I don't have much experience with Maven, so I'm not sure.
