AH Ok, that's why we're not seeing a ttyUSB0 (difficult to troubleshoot over Reddit) My article assumes that you're using something like this:

http://www.amazon.com/NooElec-Adapter-Harnesses-Jumper-Compatible/dp/B009GXEF8A


You're just using a plain old USB cable If that's the case, you MUST connect your CHIP to the USB cable, give the CHIP a minute to boot up, then:

$ ls /dev/tty

If you're connected to CHIPs USB port with a micro cable, what you're hoping to see is a device called ttyACM0.

If you see this, you can connect to he device using screen like so:

$ sudo screen /dev/ttyACM0 115200

If you /dev/ttyACM0 does not appear after a minute or so of plugging in your CHIP, then it's likely that you got one of the bum boards, and need to reflash it.

If you need to reflash it, start your vagrant up again by changing dir into where you installed CHIP-SDK

$ vagrant up
$ vagrant ssh

Once authenticated to the CHIP VM, Connect a jumper (piece of thin wire on your CHIP from the GND GPIO to the one labelled FEL. Do not plug your CHIP in to the computer yet!

(you should be in your vagrant version of the CHIP SDK environment you downloaded!!)

$ cd CHIP-tools
$ ./chip_update_firmware.sh


The console should say :

waiting for fel. . . . . . .

Plug your CHIP into the USB port now. That jumper must be in place BEFORE applying power to CHIP. If for any reason this process gets messed up, just do it over... plug in the CHIP after the computer says "waiting for fel . . . "

It should automatically detect the CHIP, and start the flashing process. It will download an image, and apply it to your CHIP.

Let the process go, until it returns you to the command prompt.

When it's done, remove the jumper wire, unplug CHIP from the USB connection. Plug it back in to the USB connection and repeat the first steps in this message (you're still in your vagrant client) :

$ ls /dev/tty


look for ttyACM0. if it's there...

$ sudo screen /dev/ttyACM0 115200

You should be prompted to log in... IF for any reason you can't find ttyACM0, it's likely because the CHIP has not been flashed (it will only appear as a device like that after it has successfully booted up.

Let me know how this goes!

These should support ARMbian just fine, the NAND is the only thing that doesn't work on mainline Linux with the exiting NTC CHIP.

Working on the write-ups now, but I've run both SlackwareARM-Current and Arch ARM on mine with the SD slot added. Works fine except that the GPU driver (Lima) is still not in the current Linux kernel (it is accepted for the next release though). I built a custom kernel with it enabled and there are still some things that need to be implemented to make it really usable so hopefully by the time 5.2 is released it will be working better. I tried to get the closed source Mali blobs working but was unable.

The WiFi driver is also still in staging, but works for me in the USA (my understanding is other countries use slightly different channels/frequency setups and may or may not be implemented in the firmware currently). Not sure about bluetooth, I haven't really tried it yet.

With the eMMC instead of the NAND, these shouldn't have any issues running whatever ARM ported distro you want. AFAIK though Raspbian is specifically for Raspberry Pi devices. ARMbian should be similar enough though.

One other thing to consider is that it does essentially have the Pi UPS built into it (this thing: https://smile.amazon.com/Raspberry-Battery-Charging-Protection-Output/dp/B07DB78PGJ/ref=sr_1_5?keywords=pi+ups&qid=1559244296&s=gateway&sr=8-5). That can be a big deal for certain projects. Just needs to be connected to a LiPO battery via its header.

> I would like your help pointing (pun intended) me in the right direction

No, no, you want some pointers for what to do next.

You can't learn just by looking. You need to pick a goal, then try to implement it. When you have very specific questions, you can ask here or stackoverflow. Don't do something complicated at first: Start with a trivial game like tic-tac-toe. Get it all working end-to-end, then start adding features to transform it into something interesting.

But don't forget this is an entire Linux-based computer, so you don't have to only use the tools that came with it. There are 1000s of games for Linux, and hundreds of game-building environments. Plus, there are lots of languages (Python, Lua, Ruby, Go, NodeJS, etc), and plenty of ways to paint a GUI (i.e. SDL, OpenGL, etc).

In many games, they only use C++ for the low-level bits, then wire up the high-level logic with a scripting language like Lua.

P.S. I've heard this is a good book.

I see that guide suggests a 3 W amp... when I did this mod I ended up using this 25 W (!) amp, and wondered why the CHIP would shut down whenever i played sound.

I just ordered THESE and I'm planning on trying to use little speakers I ripped out of an old laptop that was getting recycled.

I bought from this seller and the package was like i got it out of the clearance at Walmart, but it worked:

https://www.amazon.com/gp/product/B07HJHV4Z1/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

​

Now i got to flash this thing, cause it came with the Desktop UI.

​

Side note, Does anyone have the code to install the ADAFRUIT screen? Got the screen after i broke original chip.
