    A set of Wishbone Controlled SPI Flash Controllers

    Here's the flash controller repo I use. There's a flash controller in there for SPI, Dual SPI, and Quad SPI. The Dual and Quad SPI controllers need a device specific startup script to get them into the right mode. This script should be fairly well explained by the comments. You should find at least one of these controllers that works for you. More recent versions of the controller have a Wishbone arbiter within them -- they're just not checked in the repo yet. (DSPI, QSPI). This makes it so the design fully supports two two Wishbone ports: a config port by which you can send any value and the memory mapped read port. (You can't use both at the same time.)

  • dbgbus

    A collection of debugging busses developed and presented at zipcpu.com

    I've got a couple different encodings I use to push data over the serial port. Here's the hexbus encoding for example, although I more often use the WBUBUS encoding which you can find attached to many of my projects. They're all based around what I call a "debugging bus" and a "devbus interface". It's really easy to use--once you have it set up.

  • zbasic

    A bare bones, basic, ZipCPU system designed for both testing and quick integration into new systems

    Here's sort of a generic repo you can look at which might give you some ideas.
