Following on from the previous workshop, we will be continuing with the theme of NetBSD on embedded platforms. This time covering GPIO access with lua and rapid development with Rump kernel, which we did not get to in the previous workshop due to the lack of time.
If you did not get to attend the previous workshop, not to worry, notes are available and assistance will be provided on the day.
You will need to bring:
- Your own laptop (running Windows, Linux or Mac OS X);
- A Raspberry Pi or BeagleBone Black;
- An appropriate SD card for your board;
- USB card reader to write a new OS image onto said SD card;
- An ethernet cable to connect board to laptop and/or a USB UART/FTDI adapter to access the board via the serial console.
Windows 10 users

Windows 10 / Linux (Debian/Ubuntu) users

Mac OS X users
Install GCC or clang via Xcode or command line tools.
Everyone should fetch the source code for NetBSD:
Download all source archives (.tgz files) from http://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/201704270800Z/source/sets/ .
(It is likely the above URL will become invalid as old builds are purged and new ones are generated. Substitute 201704270800Z with the most recent release available on http://nycdn.netbsd.org/pub/NetBSD-daily/HEAD).
Extract all fetched source code files. In your terminal, enter:
for file in *.tar.gz
tar -xzf $file
Any questions should be directed to the discussion list.
