About

CHIP is a 9USD board, bas on Allwinner R8 (an A13 rebranded).

Lsusb

It has by default an Ubuntu distro on its internal flash.

It shows up as a /dev/ttyACM0 when connected and powered via the USB port (you have to wait for a while the time the system boots). Let's hope the device does not consume more then 500mA.

Lsusb shows:

Bus 001 Device 010: ID 0525:a4a7 Netchip Technology, Inc. Linux-USB Serial Gadget (CDC ACM mode)

Dmesg shows:

[71662.660018] usb 1-1.1: new high-speed USB device number 5 using ehci-pci

[71662.785679] cdc_acm: USB Abstract Control Model driver for USB modems and ISDN adapters

You can access this /dev/ttyACM0 via screen and get a console:

$ screen /dev/ttyACM0 115200
Debian GNU/Linux 8 chip ttyGS0

chip login:

The login/password is chip/chip. Once you have a shell, you can do a "sudo bash" and be root with the same password.

Serial

You can access a similar serial console via the GND, TX and RX pins located on the first header. The GND, TX and RX pins of the CHIP connected respectively to the GND, RX and TX pins of the USB serial adaptor.

Problems

  • kernel crash when you remove g_serial kernel module, see here
  • does not reboot when installing 4.4 kernel (at least could not ping it, need to attach the serial console to find out)
