DebianOn is an effort to document how to install, configure and use Debian on some specific hardware. Therefore potential buyers would know if that hardware is supported and owners would know how get the best out of that hardware.

The purpose is not to duplicate the Debian Official Documentation, but to document how to install Debian on some specific hardware.

If you need help to get Debian running on your hardware, please have a look at our user support channels where you may find specific channels (mailing list, IRC channel) dedicated to certain types of hardware.

Important Note






Power Management



Bluetooth is provided by an on-board SDIO Broadcom chipset BCM43241 rev B5. It requires a binary firmware file to be enabled. This chipset is supported only by the upstream Linux kernel and BlueZ stack, both of which are not (yet) packaged in Debian for the time being (early March 2016).

Support for the BCM43241 rev B5 chipset was added in early March in the bluetooth-next kernel development tree. It is expected to be officially part of Linux 4.6 or 4.7. Building a custom kernel is required in the meantime, including the following commit: Add BCM2E55 ACPI ID used in Lenovo ThinkPad Tablet 8.

Enabling this Bluetooth chipset is done via the new btattach command, released in BlueZ version 5.37. Until this version is packaged in Debian, instructions about how to build it can be found here Building Bluez 5.37 on Debian Jessie. The btattach command is built into "debian/tmp/usr/bin/".

Then the binary firmware file must be copied in /lib/firmware/brcm/BCM.hcd and can be found on the original Windows partition. It has the following format "" with the current version being BCM4324B5_002.006.006.0601.1170.hcd .

 # cp ./BCM4324B5_002.006.006.0601.1170.hcd /lib/firmware/brcm/BCM.hcd

Finally, Bluetooth can be enabled with btattach built previously:

# btattach --bredr /dev/ttyS1 -P bcm &
Attaching BR/EDR controller to /dev/ttyS1
Switched line discipline from 0 to 15
Device index 0 attached

and hciconfig can be used to check that the chipset is properly enabled:

$ hciconfig -a

Upon reboot, the btattach command will have to be entered again until btattach is fully supported by the Debian boot scripts.
