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- out/host/linux-x86/bin/acp -fp out/target/product/msm8960/obj/KERNEL_OBJ/arch/arm/boot/zImage out/target/product/msm8960/kernel out/host/linux-x86/bin/mkbootimg --kernel out/target/product/msm8960/kernel --ramdisk out/target/product/msm8960/ramdisk.img --cmdline "console=ttyHSL0,115200,n8 androidboot.hardware=qcom user_debug=31 msm_rtb.filter=0x3F ehci-hcd.park=3" --base 0x80200000 --pagesize 2048 --ramdisk_offset   0x109c000 -z --output out/target/product/msm8960/boot.img.nonsecure openssl dgst -sha256 -binary out/target/product/msm8960/boot.img.nonsecure > out/target/product/msm8960/boot.img.sha256 openssl rsautl -sign -in out/target/product/msm8960/boot.img.sha256 -inkey device/qcom/common/qcom.key -out out/target/product/msm8960/boot.img.sig dd if=/dev/zero of=out/target/product/msm8960/boot.img.sig.padded bs=2048 count=1 dd if=out/target/product/msm8960/boot.img.sig of=out/target/product/msm8960/boot.img.sig.padded conv=notrunc cat out/target/product/msm8960/boot.img.nonsecure out/target/product/msm8960/boot.img.sig.padded > out/target/product/msm8960/boot.img

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

Questions

 * Is there a serial port?
