Last few days i was playing with an Infocast 8″, the goal was to change the base OS provided by Insignia Inc. and replace it with the Angstrom Linux Kernel provided by the Chumby OpenEmbedded packages builder. For some reason there’s no similar images available for download.

After doing minor tweaks to the chumby-oe project, get some help from Guy Carpenter (thanks!) and fix some bitbake files, i managed to create a new bootable image with Wifi support (i mention this because the Marvel wifi chip requires some specific firmware files)

Infocast 8 booting Angstrom Linux Kernel

Now connect to the Wifi AP is a little tricky, you need to set something in the following order:

# iwpriv mlan0 setregioncode 0×10
# ifconfig mlan0 up
# iwconfig mlan0 mode managed
# iwconfig mlan0 key YOUR_WEP_KEY
# iwconfig mlan0 key on
# iwconfig mlan0 essid YOUR_ESSID
# udhcpc -i mlan0

After that you will be able to connect to your AP and have network access.

You can download the ROM image from here, or if you prefer, you can browse the whole content. Once you get the ROM image you need to burn it into the internal 2G SD Card, you can do it with: dd if=rom-chumby-silvermoon-chumby-starter-image.img of=/dev/sdX bs=8M. Make sure before to run the dd command, do a manual umount for each partition.
