No more time travelling

A recent kernel patch fixes the instability that was causing the rcu errors I was having in many of my PinePhone boards.

I have tested this patch on all of my boards and the rcu errors have gone away. I can run them at 624MHz DRAM clock and not have any hangs or time jumps.

The patch has made it into megous kernel, so any distribution that uses it will get the update.

Flexible GPS Antenna

I added a flexible passive GPS antenna to one of my PinePhones. These antennas are meant to be adhered directly to the inside of a plastic enclosure, far from any metal or ground planes. The datasheets I have read for similar antenna recommend at least 12mm distance to the ground plane. This particular antenna I got off of eBay from China, and has no datasheet. It does work quite well though. I taped the antenna to a piece of plastic from a SIM card to make it more rigid. It is paper thin, except for the area where the cable is soldered. Like on the Franken-Phone I removed the U.FL connector from the end of the cable and soldered it in place. This time I removed the spring contacts so that it would not make contact with the existing antenna in the mid-frame. I left the spring contact for the WiFi antenna intact. I shaved some of the plastic from the mid-frame so that the cable would fit between it and the metal shield of the modem. I also cut a slot in the back case with a Dremel cut...

Franken-Phone

I decided to take the worst performing PinePhone PCB and turn it into a hardware test bed. This is the 3GB 1.2b upgrade board that fails my compiler and memtester tests . It will time jump even with the RAM running at 492MHz. It is usable. With the serial adapter you can login to the serial console without an attached screen. Once WiFi/SSH is configured you can do everything remotely. I have also used wayvnc to remotely connect to the graphical desktop. I bought a large flat aluminum heatsink from Amazon to use as a base. I cut up a sheet of thermal pad material (sold for use with 3d printer glass hot beds). The pad is sticky and holds the PCB and battery to the heatsink. The battery is not the correct type/size for a PinePhone battery. It is an old battery I found in a drawer that has the same pinout, works fine. The micro USB breakout board has the VBUS and Ground soldered directly to the pogo pin pads. The loose orange wire at the bottom is soldered to a tiny pad next to the ke...
