Building

Code and instructions for building Android are here.

If you want to build just the kernel:

make out/target/product/msm8960/boot.img

or without the Android build system:

make -C kernel O=../out/target/product/msm8960/obj/KERNEL_OBJ ARCH=arm CROSS_COMPILE=arm-eabi- msm8960_defconfig
make -C kernel O=../out/target/product/msm8960/obj/KERNEL_OBJ ARCH=arm CROSS_COMPILE=arm-eabi-

Power

  • Disable USB charging:
echo 1 > /sys/module/pm8921_charger/parameters/disabled
  • Battery current and voltage:
cat /sys/devices/platform/msm_ssbi.0/pm8921-core/pm8921-charger/power_supply/battery/{current,voltage}_now
  • EPM sensors can be read using the epmread tool or from sysfs:
cat /sys/devices/platform/epm_adc/ads?_chan?

However the EPM values seem to be nonsensical on the APQ8064, at least for the CPU cores (channels 0, 3, 5 and 7).

Serial

  • The serial port /dev/ttyHSL0 is exposed (CMOS 1v8 levels, default 115200 8n1) via the dock connector on the bottom edge of the device. The supplied HDMI+2xUSB adapter can be easily hacked to access the necessary pins. (TODO: which pins are they?)
