Information

currently pmOS only have the WiFi variant for this device (Device package here). To use it, choose samsung-n5110 on pmbootstrap init.

The device has a 3G variant (n5100). See the Exynos4412devices at Replicant wiki that can be followed at See also section for more details.

While Galaxy Note x.y is not part of the Midas family, it is part of a very near relative, the Kona family, which uses the same Exynos4412 SoC as the Midas family. Here is a list of Kona family boards here from Replicant wiki. See the chipset page for more details.

How to enter flash mode

Hold Power + Volume Down + Home. When prompted, release all buttons and click Volume Up.

How to enter recovery mode

Hold Power + Volume Up + Home. When the Samsung logo appears, release all buttons.

Installation

System image

Currently pmbootstrap can produce recovery zip that installs pmOS into system partition and boot partition.

To create the system image and the flashable zip:

$ pmbootstrap install --recovery-zip
$ pmbootstrap export

Then get a recovery like TWRP to install it.

Kernel image

Flashing of the kernel works with heimdall, installation on the system partition works at least with adb sideload using TWRP (did not try heimdall). Installation on the sdcard should work, too (untested).

N5110 can be chosen as a device during the init, seeing how the hardware is identical(the difference is that n5110 is the wi-fi version, this would mean that the modem would not work)

flasher flash_kernel at flash mode should work currently, untested though (just pick up the boot.img from armv7_native and install manually via TWRP)



Mainline Kernel

Currently status

Currently there is a WIP kernel repository at https://gitlab.com/nexplorer-3e/linux-exynos4 , To use it you need to copy the necessary files from Device package to make a new device differ from current samsung-n5110.

What is working

  • 3D acceleration seemed working. Lima driver is loaded and there is a drm file under devfs. The biggest problem may be the bad performance of Mali-400 MP4 on modern DEs.
  • WiFi working but it takes a long time to initialize. and the bcm4334 only supports 2.4G.
  • USB Networking is working but it cannot use the IC config from midas device tree. Otherwise, the usbnet won't work.
  • Charger (Fuel gauge & Charging IC)
  • Display & Backlight
    • NT71391 is very rare. Porting these device not only need patience, but only to take the look of recent driver changes for there are some information that may not covered by the blog written for the driver.
  • Touchscreen

Working but untested

  • Button except the power button
  • Sound

Not working

  • IR
  • S-Pen
  • USB Networking with MHL configured
  • Camera
  • Modem (and cannot test since I only have Wifi variant)
  • GPS
  • Sensors (untested)
    • Accelerometer
    • Magnetometer
    • Hall effect sensor


May be useful data

Device Info
Element type Element Works? Notes
Chipset Exynos 4412 Y Supported in mainline
Graphics Mali-400 MP4 Y Poor performance and missing OpenGL 3 support (google lima driver for details)
Charging IC max77693 P Supported in mainline; cannot configure USB role otherwise the USB Networking is gone
Audio WM1811 P untested, seems works but need extra UCM configuration from other device packages
PMIC S5M8767 - Supported in mainline
Fuel gauge MAX17047 Y Supported in mainline
Touchscreen Synaptics S7301 Y Similar to another two device with mainline Synaptics RMI4 driver.
Buttons gpio-keys - power button is working, other untested. the touch button seems not working
WiFi, Bluetooth BCM4334 Y Driver in mainline.
Display BOE Panel, NT71391 IC Y Driver in kernel fork. See also: Blog post about getting the display working
Backlight LP8556TMX Y PWM-controlled backlight controller. Seems to have a weird issue where setting it to 100% causes the backlight to shut down (though this is lazily worked around in knuxify's fork). Also seems to forget ROM settings after suspend.
Camera Sony ISX012 and Siliconfile SR130PC20 Both aren't in mainline
IR N
MHL sii9244 N see the Charging IC section above
Modem N TODO: Check Replicant
GPS N

  • Replicant is also interested in mainlining this device and replacing the bootloader with u-boot and would like to collaborate with us [1].


Downstream

What works

  • Weston including touch
  • Xfce4 (recommended) including touch and pen
  • WiFi using the firmware-samsung-i9305 - but: NetworkManager does not work, see #1461
  • Bluetooth works partially as described for the Galaxy SIII but the device is /dev/ttySAC0
  • Audio, see Audio#WM1811 for more instructions. Both an pre-configured saved state as well as the ucm profiles are included.
  • charging-sdl

What does not work

  • S-Pen
  • MHL
  • Bluetooth pairing with bluez5 (bluez4 is working, more on that soon)
  • osk-sdl - FDE most likely does not work as some kernel options are missing (can be easily fixed probably if FDE is desired).
  • GPS
  • Camera
  • Sleep etc.
  • poweroff on shutdown (halt) command - make sure you really turn the device off or your battery will be totally depleted.
  • 3D acceleration (plasma mobile is very slow)
