Loading Your Root Filesystem
Sometimes it's convenient to copy a root filesystem on to a Balloon from a USB stick. This is how to do it.
The instructions below assume that you have a file debianrootfs.tar.gz which you would like to load into the Balloon board, and that you have a serial console and programming board with USB host connector set up. The USB host connector requires that the Pinko FFC is connected. The USB stick should contain a gzipped tarfile of the root filesystem.
First, get a serial connection to your Balloon board's console working. Switch on the board, and press space to get to the bootldr prompt. Boot into the boot/recovery kernel:
set bootscript=exit boot flash
Log in as root (no password). Mount the root filesystem:
and now mount your USB stick:
On the Balloon board, change to the right directory and delete any existing filesystem contents:
cd /mnt/root rm -rf *
Deleting the existing filesystem may take 5-10 minutes.
Now unpack the new filesystem (change the filename to reflect yours):
tar xzvf /mnt/sda1/yourfilesystem.tar.gz
The process takes some time, so make some tea. It will probably take about 10 minutes.
