Changelog

Updated kernel with adc drivers. Can read AUX1 and AUX2 now using sysfs. 
using 'cat /sys/devices/platform/jz4780-adc/jz4740-hwmon.0/in0_input'
using 'cat /sys/devices/platform/jz4780-adc/jz4740-hwmon.0/in1_input'

Upgrading to Debian 8 / Jessie

Note: Please use CI20 Distros#Debian unless you know what you are doing.

Before you upgrade

Before upgrading you must ensure you have a kernel with CONFIG_FHANDLE enabled since the version of udev in jessie now requires it. The kernel supplied in the NAND image does not have this option enabled. You can test if you have it by running

grep 'T sys_open_by_handle_at' /proc/kallsyms

Old kernels will print nothing, up to date kernels will print the symbol address.

After you upgrade:

  • Graphics acceleration will not work (the powervr drivers currently don't work with xorg 1.16).
  • MPlayer will be removed.
  • Your system will be converted to run systemd.

Upgrading

All commands should be run as root.

Move PVR specific xorg.conf out of the way

mv /etc/X11/xorg.conf /etc/X11/xorg.conf.pvr

If you are running the rootfs from an SD card, comment out the ubi boot line in fstab by adding a # at the start of the line

nano /etc/fstab

Remove PVR module from /etc/modules

sed -i 's/pvrsrvkm//' /etc/modules

Update sources.list to point to jessie

sed -i 's/wheezy/jessie/g' /etc/apt/sources.list

Update package lists

apt-get update

Upgrade packages

apt-get dist-upgrade
APT may decide to remove some packages here - look carefully at the list before pressing yes.
During the upgrade you will be asked what to do about a modified version of /etc/lightdm/lightdm.conf. Select N here (selecting Y is ok, but will disable autologin).

To save some space you can remove some old packages by running

apt-get autoremove
apt-get autoclean

If everything goes well, reboot

reboot
