migen_uart
migen_uart is a minimal UART meant for no-hassle testing purposes and an
example of integrating fusesoc with
migen via the former's generator API
(GAPI 1.0).
Quick Start
Initialize the fusesoc library and make sure fusesoc sees the
migen_uart_gen generator and migen_uart and sample loopback cores:
fusesoc library add migen_uart .
fusesoc list-cores
fusesoc gen list
Generate a loopback core for the iCEBreaker and program the bitstream:
fusesoc run --target icebreaker cr1901:migen:uart-loopback
iceprog build/cr1901_migen_uart-loopback_0/icebreaker-icestorm/cr1901_migen_uart-loopback_0.bin
Once the above is done, open a serial terminal at 19,200 baud connecting to the iCEBreaker. If you type characters and see them echo'd back, congratulations, you have successfully used the loopback core provided w/ this library!
Take a look at loopback/loopback.core as well as the help from fusesoc gen show migen_uart_gen
for examples on how to use the migen_uart core (which only provides the
generator at present, and nothing else)!
Clean
Assuming you are in your working directory with fusesoc.conf, you can clean
your work tree by running:
rm -rf fusesoc.conf build/ fusesoc_libraries
