Sunxi support

Current status

No support of the B300 SoC.

U-Boot

The U-Boot is not distributed. Bookeen does not have the sources and Bigme does not provide them.

Linux Kernel

The Linux Kernel is not distributed. Bookeen does not have the sources and Bigme does not provide them.

Adding a serial port (voids warranty)

Notea UART pads

You can attach a serial port to the Allwinner B300 by soldering the UART pads on the PCB, see UART howto.

Device disassembly

Gently unclip the black plastic case around the screen with plastic tools. Unclip the USB port last. Be careful with the button, it is not firmly attached.

Remove the aluminium covers on the PCB.

Locating the UART

Notea soldered UART

The UART pads are labelled G, R, T, V for GND, RX, TX and VCC. Use 3.3V and do not connect VCC.

FEL mode

There are two known methods to trigger the FEL mode, neither triggers boot1.

By sending '2' to UART

With UART active on /dev/ttyS1: - Make sure baudrate is correct: stty -F /dev/ttyS1 115200 - Spam 2 character on UART: while [ true ]; do echo -n 2 > /dev/ttyS1; sleep 0.005; done - Reboot the tablet

The tablet should reboot in FEL mode:

Using `fastboot oem efex`

Connect the tablet to your computer
Install an app on the tablet to open the AOSP Parameters
Go to system settings > about
Tap multiple times the build version until you're in developper mode
Open developper settings
Change USB mode to PTP
Enable the USB debugging
Use adb on your computer (you'll need to trust your computer on the tablet)
adb devices will show you if you're properly connected
Use adb reboot bootloader, the tablet will freeze and reboot to the bootloader so you will only see the *Notéa* logo, fastboot devices will say:
```
Android Fastboot         Android Fastboot
```
Use fastboot oem efex
Force rebooting the tablet, by holding the power button
