DBE62
From ThinCan
The DBE62 retained the AMD Geode LX design used in the DBE61, upgrading to VIA VT6122 Gigabit Ethernet controller and adding possibility for optional internal USB extension daughterboard.

Variants
- DBE62D-700: 512KB NOR Flash for BIOS, 256MB DDR SDRAM, 64MB NAND Flash for OS payload — delivered with an LX700 as preproduction samples.
Driving the DBE62
- The DBE62 is covered by the same Linux and X.org drivers as the DBE61.
- The VIA VT6122 network controller is covered by Linux kernel module via-velocity.
- If you need to swap phone out and master channels for the audio, the following kernel command line snippet would do that for built-in drivers:
snd-ac97-codec.ac97_quirk=swap_hp cs5535audio.ac97_quirk=1
Booting the DBE62
The DBE62 benefited from the Coreboot development efforts made for the DBE61. Support in Coreboot-v3 is good, but extensive testing and stress testing is still to be conducted.
LPC Dongle on DBE62 HOWTO
- Developing firmware for the DBE62 requires an Artec Programmable LPC Dongle with FPGA revision 04 or later.
- Writing BIOS image to dongle: ./dongle.py -c <dongle_port> <bios_image_file> 0x380000
