CHIP (C.H.I.P.) was a single-board computer crowdfunded by now-defunct Next Thing Co. (NTC), released as open-source hardware running open-source software. CHIP and related products are discontinued.

Identification

On the back of the device, the following is printed:

CHIP v1.0

Sunxi support

Current status

CHIP has some support in mainline U-Boot and kernel (defconfig and device tree). CHIP's SLC NAND is not supported by Mainline U-Boot.

Manual build

You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.

U-Boot

Sunxi/Legacy U-Boot

Chip is not supported by Sunxi/Legacy U-Boot

Mainline U-Boot

Use the CHIP_defconfig build target.

Linux Kernel

Sunxi/Legacy Kernel

Not supported.

Mainline kernel

Use the sun5i-r8-chip.dtb device-tree binary.

Locating the UART

The UART located is on the header named U14. On this header Pin 1 is Ground (GND), Pin 3 is TX (Transmit) and Pin 5 is RX (Recieve). To establish a connection the TX of the Chip must be connected to the RX of USB-UART Converter and the RX of the Adapter to the TX of the Chip, Ground is connected to Ground. Do NOT Connect 5V or 3V to the Chip. Please note that the UART of the Chip uses 3.3V ( RX of the Chip is 5V tolerant ).


   GND -> GND on the CHIP
   TX -> UART1-RX on the CHIP
   RX -> UART1-TX on the CHIP


FEL mode

Shorting out the FEL and GND pins before connecting power will cause the device to boot in FEL mode.

Tips, Tricks, Caveats

The Chip requires 2A to run without issues if less Power is provided a brownout may occure.

If USB Devices attached to the Chip require more then 500mA the No Limit version needs to be Flashed.

A single Cell Lithium battery can be attached to the Chip.

If a external Antenna is required aUFL connector can be soldered on the back.


Device specific topic

Other than most Single Board Computers, the Chip needs to be flashed with a Operating System.

The Vendor provided only Debian Images with different Flavours ( Desktop, Server, Pocketchip ).

Those Images are provided in proprietary and undocumented format with the Filetype .chp

These files are designed to be used with a (now offline) Website and Chrome addon.

Fortunately several Open Source alternative exist.



Flashing (Debian/Ubuntu)

Clone the Repo from Github.

git clone https://github.com/Thore-Krug/Flash-CHIP.git

Change into the Directory.

cd Flash-CHIP

Make the Script executable

sudo chmod +x Flash.sh

Execute the script

sudo ./Flash.sh

Select the version you want to install. Wait until the installation finishes.

Troubleshooting

Use USB 2

Refresh Apt Repos

sudo apt update 



Flashing (MacOS)

Clone the Repo

git clone https://github.com/Thore-Krug/Install-Flash-Chip-Mac

Change into the Directory

cd Install-Flash-Chip-Mac

Make the Script executable

 sudo chmod +x Flasher.sh

Install all necessary Dependencies.

./Flash.sh install-all

Flash your Chip

./Flash.sh flash

Select the version you want to install. Wait until the installation finishes.


Or read the Help

./Flash.sh help


Troubleshooting


Kill the Script with ctrl + C

Read the output if something is not installed or Permissions are missing

Just restart the Script (fixes most of the Problem with FEL and Fastboot )

If this does not help reboot, retry

Open an Issue on the Git Repo.

Use USB 2




Dips

Like on other Single Board Computers, Hardware Addons wich add more functionality to the Board can be used. These Addon Boards are called Dips, the Vendor NTC (Next Thing Company ) provided HDMI and VGA Dips. But other User created other Dips too, like a USB Hub or a SD Card addon.
