Since, COM Express cannot be tested in proto 1, this is a top priority. But we also made the layout to be exactly to what they would be in the final version. This means high speed signals are much closer to each other compared to proto1.

Rule: solder 1 module at a time. Keep checking for power shorts. We made a soldering mistake where two close vias are bridged by solder. We figure out the error right away because we only solder in a few components at a time. In the future, the vias should be far away from the pads of other net.

Things to test: * COM Express working * VGA, USB, SATA, GBE, E-Card

The logs are written below, but this is the summary: * COM Express is powered * VGA works * Bios problem → need to send back to Kontron RMA * USB, SATA, GBE works

* COM Express hole smaller to accommodate small M2.5 screw heads * USB too close to USB7 * USB TVS3_0 needs fixing: * SATA holes needs 8mm diameter clearance holes * 150nF capacitors needs to make footprint bigger. Or put TPS in between 150nF caps. * Via under TPS has to be farther apart * power and reset is flipped

* Extra holes for standoffs. * Put expcard power regular on the other side * Express Card resistors on the bottom (blue) side is too close to each other to solder

'Wednesday, February 4, 2009' We started just the COM Express connector and the power components → 'works'

We then plug in the USB for KVM at port USB7, which is bare bone (no Chokes, etc). That did not work. We then try USB0 & 1; also did not work. It is stuck with error code '0075 or 0085'.

We thought, maybe it needs an Operating System to boot up. We decided to connect a Ubuntu Live CD through the SATA External. It did not work.

Later that night, Kai tried to use a USB CD-rom and not connect the USB keyboard and mouse;'it works'. The keyboard and mouse is then reconnected once Ubuntu loads up: 'it must be a BIOS' problem.

'Thursday, February 5, 2009' Now that we have a working system, we proceeded to knock out GBE, SATA, USB. We want to test ExpressCard, but needed to get it working in the evaluation board first.

We can't get the eval board to recognize our “Best Connectivity 1394A Firewire card”, although we are able to get another card, “Unibrain FireBoard Blue-e vers1.0” to work off of the PCI-Express slot (we typed in lspci on the command line). So we called Kontron and got a hold of 'Robert Schiedel' (858) 746 - 3204 robert.schiedel-AT-us.kontron.com. We told him the BIOS and ExpressCard problem. He told us to ship it to Kontron, which is in San Diego, CA.

'Friday, February 6, 2009' We shipped the board at 3pm.

'Monday, February 23, 2009' We got the board back. BIOS is fixed, needs legacy free bios. Express card is not working with our firewire card, but it did work on their 'SIIG RAID controller card on slot 54'.

We decided to just use the vertical PCI Express x1 implementation.
