- The files in udev-rules should be copies to
/etc/udev/rules.d
this will ensure stable names in /dev for input devices and
the ttys that talk to the 3G modem.
- Kernel can be compiled using a cross compiler. I use
angstrom-2011.03-x86_64-linux-armv7a-linux-gnueabi-toolchain.tar.bz2
from http://www.angstrom-distribution.org/toolchains/
This goes in /usr/local/angstom.
I then compile with
export PATH=$PATH:/usr/local/angstrom/arm/bin
export CROSS_COMPILE=/usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-
mkdir O
make O=O gta04_defconfig
make O=O -j8 uImage
rm -r M; mkdir M
cp O/arch/arm/book/uImage M
make O=O INSTALL_MOD_STRIP=1 INSTALL_MOD_PATH=`pwd`/M modules_install
then the uImage and modules are in 'M' ready to be copied
- Directory 'scripts' includes some sample scripts to various
simple tasks
+ vibra.py shows how to program the vibrator as a rumble effect.
+ b_host.sh helps to switch to b_host otg state (GTA04 is external
powered but plays the role of an usb host, the id pin is
not grounded in that situation). First apply power or switch on
software-controlled charging, run that script, then also connect
the usb data lines
