An installation Debian-arnhf into BeagleBone Black, To use analog input function on Linux 3.8 kernel.

The BeagleBone Black has many functions ,ADC, PWM, , , ,

But ArchLinuxArm kernel of BeagleBone Black doesn't support BONE-CAPE.

So I decided installing Debian-armhf into BBB.

My instillation is below

1) download

I used ubutu machine to make a boot micro SD card.

wget http://s3.armhf.com/boards/bbb/uboot-bone.tar.xz

wget http://s3.armhf.com/debian/wheezy/bone/debian-wheezy-7.0.0-armhf-3.8.13-bone20.img.xz

2) install

Please refer BeagleBone official site.

3) enable AIN

user change from debian to root

Completed!
