Booting Barrelfish on PandaBoard

If you are building Barrelfish for the first time, please have a look at the README file and the notes given in Getting_Started.

Instructions how to get an extra serial/uart interface connected to your computer are here.

Toolchain

In addition to the requirements listed in Getting_Started, we are using the Ubuntu/Linaro toolchain for cross-compiling ARM.

$ arm-linux-gnueabi-gcc --version
arm-linux-gnueabi-gcc (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.1) 5.4.0 20160609

Building a Barrelfish PandaBoard image

We need to build for armv7 and then run make PandaboardES:

$ mkdir build; cd build
$ ../tip/hake/hake.sh -i . -s ../tip/ -a armv7

Then run the following:

$ make -j4 PandaboardES
...
OK - pandaboard boot image is built.

This creates the boot image armv7_omap44xx_image.

Building usbboot

To boot armv7_omap44xx_image on a Pandaboard we need usbboot. The Barrelfish source tree now contains a copy of usbboot.

Additional packages for building it are required:

sudo apt-get install libusb-1.0-0-dev freebsd-glue libfreebsd-glue-0 libelf-freebsd-dev

The Makefile will build usbboot on demand. It can be built explicitly using

make tools/bin/usbboot

Booting barrelfish

Connect to the serial:

$ picocom -b 115200 /dev/ttyUSB0

And boot PandaBoard using usbboot

make usbboot_panda

You should see Barrelfish booting on your picocom window:
