Switch off the mobile
Press Vol - and Power on at startup

UART2

The SP 40 has no GPS inside. So we can use this UART2 for something else.

Soldering a 0 - 30 Ohm resistor.

  

Now we can connect to the UART2 at PIN 26 and 29.

UART2 sends some data.

Using the Android Debug Bridge and starting a remote shell

Compile a Kernel Module

Go to the http://www.pearl.de/support/ an search for Sp40
Download the kernel source.
Download the Android ndk android-ndk-r4-linux-x86.zip (only this version works. Because we need gcc 4.4.0 ).
Go into the kernel tree make modules_prepare. The kernel didn't compile.
But you can compile your own kernel drivers!!!!

 Pins on Board

1) UTX4  ( UART 4 )
2) URX1  (UART 1 )
3) PAD_USB_DP  ( USB )
4) PAD_USB_DM  ( USB)
5) PIMC ????
6) BAT
7) GND
8) URX4  (UART 4 )
9) UTX1  ( UART 1 )
10)  PON
11)  ????
