Bluetooth
Bluetooth 4.0 is in combo wireless chip BCM43142.
Install: bluez and bluez-utils

In spite of hci0: BCM: Patch brcm/BCM.hcd not found
the bluetooth module works:

Sometimes it is needed to run:
# rfkill unblock bluetooth
blueman works correctly.
Here https://forum.libreelec.tv/post-12512.html I've found a firmware for BCM43142 - BCM.hcd.
# unzip BCM.zip # cp BCM.hcd /lib/firmware/brcm/
After restart:
$ dmesg|grep -i bluetooth [ 21.606725] Bluetooth: Core ver 2.21 [ 21.606750] Bluetooth: HCI device and connection manager initialized [ 21.606758] Bluetooth: HCI socket layer initialized [ 21.606762] Bluetooth: L2CAP socket layer initialized [ 21.606771] Bluetooth: SCO socket layer initialized [ 21.663192] Bluetooth: hci0: BCM: chip id 70 [ 21.679212] Bluetooth: hci0: thinkbali [ 21.679218] Bluetooth: hci0: BCM (001.001.011) build 0172 [ 22.414606] Bluetooth: hci0: BCM (001.001.011) build 0172 [ 22.430520] Bluetooth: hci0: Broadcom Bluetooth Device (43142) [ 25.208811] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 25.208814] Bluetooth: BNEP filters: protocol multicast [ 25.208822] Bluetooth: BNEP socket layer initialized
But I felt no any difference without or with firmware.
Card Reader
Works out of the box. Tested with SD card 512 Mb.
Dual boot with Windows
To boot Windows 7 it is needed to switch on CSM
at BIOS. Otherwise Windows boot hangs at logo.
Set the BIOS setting OS Selection
in the Advanced
menu to Windows 7
.
Freezing on 4.x kernels
Pentium N3520 processor is affected by the c-state bug: https://bugzilla.kernel.org/show_bug.cgi?id=109051
Workaround: add intel_idle.max_cstate=1
kernel parameter.
