ICE40 up5k Internal internal oscilator and ip's

Question

i can see that icestorm support ice40 ultra plus up5k fpga, but this chip has internal osc, is there any example what i use it ? of course using yosys, icestorm (opensource) and is there some examples where i can use build in IP,s such as SPI, I2C, PWM ? Thanks

No, it does not. There has been some preliminary work, but it is far from generating any up5k bit streams, with or without the internal oscillator. Only the devices listed on http://www.clifford.at/icestorm/ are supported (see table under the "What is the Status of the Project?" heading).
