EuroBSDCon Bucharest Romania

The Wikitravel page for Bucharest has some scary warnings about taxis. I didn't heaer any horror stories from conference goers, but there was a large variation in prices for the same journey.

He held a two day DevSummit before the conference proper. A DevSummit is a chance to talk through technical issues and hash things out face to face. We did some planning for FreeBSD 13 with the idea of setting GGoals for the release.

We tried to match a bit of a hackathon with the DevSummit, but the tutorial schedules meant we couldn't focus the time very well and it was broken up.

Day Two concluded with announcing the location of the next EuroBSDCon, Lillehammer Norway.

EMF Camp 2018

Skeleton Dome

EMF Camp is a giant hacker camp that occurs in the deep South of England. It managed to attract nearly 2500 people into a field for four days at the end August.

EMF Camp 2018 was the first time I have volunteered to help with the organisation. I volunteered to help out the content team earlier in the year, it wasn't until the week before that we realised lightning talks needed more organisation. Foolishly I stepped up and got a weird split experience between attending the camp and running a tiny slice of it.

It wasn't sooooo awful, I'll probably do it again.

EMF Camp Map

I attended EMF Camp 2014, since then they have really managed to integrate well with the village system used at other camps. The map shows all the spontaneous events that people put together during the camp, the adage 'it is what you make it' really comes out at these events with many participants helping to make it hole.

Border control point ShoutyTel

In our own way the Scottish Consulate contributed too, with our bureaucratic role playing game going beyond the pale and expanding into operation of a phone network (cups and string) and a Hard border from the rest of the camp.

America's Hackercamp

Milliways Dome

Toorcamp is America's Hackercamp, it happens on the stunning Orcas Island an hour or so North West of Seattle. Hacker events always manage to create their own neon lit world, Toorcamp took this to another level and sequestered 500 hackers away in a idillic resort in the Pacific North west and even then it poured on the neon lighting effects to keep us in a dream world.

LED Gateway

Doe Bay resort spreads over three regions, a bay area (were I camped with Milliways), an island outcrop and a field at the top of a hill. This division (especially the hill) make it less enticing to move around the site. It also meant that the nosiy area in the bay, by being far away from most of the camping, was able to go all night long without disturbing too many people.

Call to anywhere but Shady Tel

Toorcamp is serviced by a group of telephone enthusiasts called Shady Tel. They operate a highly reptuable phone company in the American fashion, offering service anywhere on the camp site, whether near an exchange or on a boat out in the bay.

I hate talking to people on the phone, but I found this limited network to be a ton of fun. I must have spent hours wardialling around trying to find people to call. Once I discovered the maintainence line that echo'd back your phone number I started going around and collecting interesting phones.

Payphone

Because we are hackers on top of this phone network highly ammusing things pop up. Milliways ran a pager network and from their payphone I spent many hours paging people to call numbers. Knowing how to find numbers for a phone I started paging people to call me at random places.

Stage Dome

The Doe Bay resort that hosted Toorcamp would be a wonderful place to go even without an amazing hacker camp in toe. Rather than attempt to describe the event it is easier to link to the 10 intervies the amp hour podcast did on site.

The final night nature decided to turn on a smoke machine and join the party.

FreeBSD on the Intel Compute Stick STK1AW32SC

Compute stick pieces

A FreeBSD developer has been tricked somehow into working on EFI boot. A large missing piece has been support for 32 bit EFI. Many devices with Intel mobile SOCs have shipped with bios which only support 32 bit EFI for boot even on 64 bit processors.

Rumour had it the Intel Compute Stick STK1AW32SC was one of the platforms with only 32bit EFI. This compute stick has a SOC from the Cherryview family, the same as the GPD Pocket, I want FreeBSD to support this SOC well and 32 bit EFI to boot is a part of that.

This compute stick is end of life and looking around I saw a few on ebay. I managed to win an auction for a new in box compute stick, getting it for about £50. For that I got:

I asked Allan Jude to take his compute stick to the DevSummit at EuroBSDCon, while he was grabbing it someone else piped up and claimed to have run FreeBSD on the compute stick before. Turns out there is a bios option to switch between 32bit boot and 64bit boot.

Yes, our deliberate FreeBSD brick actually works. Here is how to install FreeBSD on a Compute Stick:

BIOS default settings

Break into the bios by hitting F2 at boot.

BIOS Boot 64

In 'Configuration' change Operating System from 'Windows 32-bit' to 'Windows 64-bit'

Reboot and break into the boot menu and choose your FreeBSD USB stick.

As with the x5 box there is an issue where the uart causes the compute stick to hang.

Break into the loader menu and set:

OK unset hint.uart.1.at
OK boot

Install as normal

Before rebooting at the end of the installer you need to edit device.hints to disable the uart again.

# chmod +w /boot/device.hints
# vi /boot/device.hints
....
hint.sc.0.flags="0x100"
hint.uart.0.at="isa"    # comment this line out
hint.uart.0.port="0x3F8"
....

WiFi

Bluetooth is present in the dmesg, but we need to load the iwm kernel module then we can configure WiFi as normal.

# kldload if_iwm

Graphics

Since setting up the x5 box in January our FreeBSD has has gained support for integrated graphics on CherryView SoCs. Now graphics support is available by installing and loading the drm-next-kmod.

# pkg install drm-next-kmod
# kldload /boot/modules/i915kms

Meat

I was unable to find any tear down pictures of the compute stick so I had to make some. The cast is easy to take a part, there is a single screw under a rubber foot once that is removed the rest of the top case is held on with snap fits. Inside the fan is connected with a tiny cable, the 2.4GHz and 5GHz antennas are glued to the side of the case, everything else is held down with 2 screws. 3 screws hold the heat sink assembly to the pcb.

Compute stick top

Inside there is very little to see

On the top is the SOC is in a puddble of goop, an AXP288 PMIC, 64Mb of Winbond flash and two Kingston 4Gb DDR3 Ram modules.

On the bottom there are two more DDR3 modules (taking us up to 2GB), a SanDisk SDINADF4A 32GB eMMC and an Intel 7265D2W WiFi + Bluetooth module..

One of the campgnds I used the tag line 'it happened again!'. It keeps happening and people are still upset about that year we missed. At this point it is easier to keep doing it.

hammocking

campgnd is the annual camping trip for the hackerspace. We take 10-20 people off into a remote field build up an unreasonable shanty town of tents, feed it with power and data and let our minds go.

pokedex hacking

I love campgnd, it is a chance to escape and an opportunity to test out Village for visiting larger camps around Europe. Getting away and going somewhere is a great way to increase focus, if camping isn't your thing then taking your hackerspace to a makerfaire is a great way to focus on getting projects ready to show.

It seems we are already planning campgnd 2019, if you want to join the madness drop into #scottishconsulate on freenode and ask.
