The Dash Express (HXD8) is a networked collaborative automotive GPS unit from http://dash.net/ which was developped by Openmoko.

The FCC ID is: EUNHXD8V2. It does have a debug port that is compatible with the Openmoko Debug Board v3. It is fairly hard to get to (for a FR). It sits underneath the screen.

It has 3GB of internal flash. The DFU map is below:

The serial interface is available only for u-boot. You can put it into DFU mode, and change the authorized_keys file to log into the unit.

[edit] Hardware

From the information found in the hardware documentation and kernel patches parts of the subversion repositories, the following specifications can be predicted. The HXD8v2 has shipped under the FCC ID EUNHXD8V2

[edit] Processor

According to https://svn.openmoko.org/trunk/src/target/kernel/patches/s3c2440-nand-disable-hwecc.patch the HXD8 will feature an S3C2440, capable of running up to 400MHz. The features are the same as the S3C2410 plus a camera interface.

[edit] Flash

According to a currently available hardware patch, the device supports 1 NAND Flash device of up to 4G. (uncertain about what kind of G that is. Could be 4Gb (which makes about 0,5GB), could be 4GB).

Personal tools

The Dash Express is based off of the legendary HXD8. The FCC ID is: EUNHXD8V2. It does have a debug port that is compatible with the OpenMoko FR debug board. It is fairly hard to get to (for a FR). It sits underneath the screen.

It has 3GB of internal flash. The DFU map is below:
