CoderDojoDC Tilde Pi

This project generates a simple Linux server that can be loaded onto a Raspberry Pi. The server will be used to teach CoderDojoDC members about the Unix commandline and let them post simple web pages.

Building

If you're using Ubuntu, you may need to install some packages to make Buildroot work. This should be sufficient:

$ sudo apt-get install git g++ libncurses5-dev bc
$ sudo apt-get install libc6:i386 libstdc++6:i386 zlib1g:i386 gcc-multilib # 64-bit Linux

After that, clone this project and run make:

$ make tilde_pi_defconfig
$ make

It can take some time to download and build everything so you may need to be patient. The build products can be found in buildroot/output/images.

Installing

Insert an SDCard on your PC and note where it appears under Linux. If the SDCard is automounted, make sure to umount everything that was mounted. Then run the following, but replace /dev/sdc with the path to the SDCard.

$ sudo dd if=buildroot/output/images/tilde_pi.img of=/dev/sdc bs=1M

Insert the SDCard into a Raspberry Pi Model B, and watch it boot over the serial port. Log in as...

Running in qemu

It's possible to do a lot of work locally in qemu. Run the following to make a qemu build:

$ make clean
$ make tilde_qemu_defconfig
$ make

Then, start up qemu:

$ qemu-system-arm -M vexpress-a9 -kernel buildroot/output/images/zImage \
          -drive file=buildroot/output/images/rootfs.ext2,if=sd \
          -append "console=ttyAMA0,115200 root=/dev/mmcblk0" \
          -serial telnet:localhost:4444,server \
          -net nic,model=lan9118 -net user -nographic

Now that qemu is started, it's waiting for you to connect to the serial port. This is accessible by telneting to port 4444. I.e.

$ telnet localhost 4444

Log in as root:root or fhunleth:fhunleth, etc. for now.
