NeuTab N7Pro

= Identification = On the back of the device, the following is printed: NeuTab Model: N7 Pro

The PCB has the following silkscreened on it: TZX-723QB6

In android, under Settings->About Tablet, you will find:
 * Model Number: 
 * Build Number: 

= Sunxi support =

Manual build

 * For building U-Boot, use the  target.
 * The .fex file can be found in sunxi-boards as

Everything else is the same as the manual build howto.

Mainline U-Boot
For building mainline U-Boot, use the  target.

Mainline kernel
Use the  device-tree file for the mainline kernel.

= Tips, Tricks, Caveats =

Through serial console
This method will NOT initialize boot1. For more information on the various ways to enter FEL mode, see the FEL page.


 * 1) Power off the device
 * 2) Start a serial terminal program (  for instance)
 * 3) In the serial terminal, hold down the 2 key
 * 4) Power on the device

The device should eventually print out the following over serial: HELLO! BOOT0 is starting! boot0 version : 3.1.0 reg_addr 0x01f00100 =0x00000000 reg_addr 0x01f00104 =0x00000000 reg_addr 0x01f00108 =0x00000000 reg_addr 0x01f0010c =0x00000000 reg_addr 0x01f00110 =0x00000000 reg_addr 0x01f00114 =0x00000000 eraly jump fel

FEL version example
$ ./fel version AWUSBFEX soc=00001667(A33) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000

ADB
This device has root access enabled by default. This means that dumping things like  from NAND is as easy as:


 * 1) Install   on a PC, enable USB debugging on the tablet, and connect the tablet to the PC via USB
 * 2) Run   from the PC to dump an image of   to the PC's working directory

Recovery mode

 * 1) Power off the device
 * 2) Hold down the vol+ button
 * 3) Power on the device
 * 4) Release the vol+ button when recovery starts

Boot log from serial port
NOTE: this log is from a device that has had its battery removed.

= Adding a serial port (voids warranty) =



The non-chip/connector side of the board has a number of test pads on it. Solder headers or wires to the pins below the large ground pad on the right side of the board (as seen with the USB port, power port, and power button facing upwards). For more information, please reference the UART howto. Note: the UART pins are shared with the µSD (MicroSD) card pins, so please do not have a MicroSD card inserted when attempting to debug this device with a UART.
