Mycelia
A bare-metal actor operating system for Raspberry Pi.
Build and run instructions
NOTE: HEAD is in active development, for a stable version the latest release is recommended.
If you are building on the RPi, just type:
$ make clean all
If you can't compile (or cross-compile) from source,
you can use the pre-built kernel.img file.
Next, copy the firmware and kernel to a blank SD card, for example:
$ cp firmware/* /media/<SD-card>/
$ cp kernel.img /media/<SD-card>/
The end state for the SD card is to have a FAT32 filesystem on it with the following files:
bootcode.bin
start.elf
kernel.img
Put the prepared SD card into the RPi, connect the USB-to-Serial cable (see RPi Serial Connection for more details), and power-up to the console.
To get to the console, you'll need to connect. Here are two ways to try:
$ minicom -b 115200 -o -D <device>
Where <device> is something like /dev/ttyUSB0 or similar
(wherever you plugged in your USB-to-Serial cable).
Alternatively, if minicom is not working for you, try using screen:
$ screen <device> 115200
Where <device> is, again, something like /dev/ttyUSB0.
The console will be waiting for an input, press <ENTER>. You should then see:
mycelia <version> sp=0x00008000
