DFU Mode Arduino UNO without soldering



I did these steps after I loaded and "empty" sketch to the board.

Code:
void setup(){}
void loop(){}
-----------------------------------------------------------------
INSTALL THE DFU PROGRAMMER (console commands)
-----------------------------------------------------------------
$ sudo aptitude install dfu-programmer

-----------------------------------------------------------------
DOWNLOAD AND VERIFY THE FIRMWARE (console commands)
-----------------------------------------------------------------
$ wget --no-check-certificate https://github.com/arduino/Arduino/raw/master/hardware/arduino/firmwares/arduino-usbserial/Arduino-usbserial-uno.hex
$ md5sum Arduino-usbserial-uno.hex
8e01ee236e70bbea43f7eb4e11c9688a Arduino-usbserial-uno.hex

-----------------------------------------------------------------
PUT ARDUINO UNO IN DFU MODE (see Picture)
-----------------------------------------------------------------
0) connect your board to the pc
1) insert 2 wires in GND pins according to the picture above
2) hold the "wire 1" on the top left 8u2 ICSP pad (AREF)
3) touch the "wire 2" against the left side of the capacitor below the RX LED (leds will blink)
4) remove the "wire 2" wire
5) remove the "wire 1" wire
NOTE: in step 3, my board actually has 2 capacitors instead of one like displayed in the picture, use the capacitor below the RX LED.

-----------------------------------------------------------------
UPLOAD THE NEW FIRMWARE (console commands)
-----------------------------------------------------------------
$ sudo dfu-programmer at90usb82 erase
$ sudo dfu-programmer at90usb82 flash Arduino-usbserial-uno.hex
$ sudo dfu-programmer at90usb82 reset

-----------------------------------------------------------------
FINAL STEP
-----------------------------------------------------------------
disconnect the board from the pc
reconnect it and you are done

NOTE: when you are done remove dfu-programmer package from Ubuntu since this package require the arduino IDE and some other tools and those versions don't work with Arduino UNO board.

Ubuntu 17.10 running on Lenovo Yoga 920 with HiDPI and touch screen support

I resized the windows partiton to the minimun necessary (100G), disabled secure boot and I also remove bitlocker key encryption on windows drive, this allows Ubuntu to see that partition and allow windows to boot with secure boot disabled, without complaning.

This makes everything go easier if you want to keep windows arround on the same disk and dual boot with Ubuntu, you should do this it helps a lot. Even after you disable this, you can re-enable it back, both secure boot and bitlocker key encryption.

Before installing on windows updates resize your windows partition, installing all windows updates will not alow you to gain as much space as possible. After resizing the windows partition to the minimium size you want, install all windows updates, bios and driver updates.

I upgraded all windows updates to the latest version and all drivers to the latest version and upgraded the bios on windows to the latest version before installing Ubuntu, I don't think this makes much differenc…

Ubuntu GNOME 17.04 running with HiDPI and touch screen support

Ubuntu GNOME 17.04 running with HiDPI and touch screen support








See my previous post on how to install Ubuntu on Yoga Pro 2 for Ubuntu GNOME 16.10.

I think Ubuntu GNOME is the best flavor of Ubuntu if you are running in HiDPI mode 3200x1800. All screen captured images are at HiDPI resolution.
Touch support Ubuntu gnome support for touch screen is pretty good on the desktop shell.
Chrome browser supports touch screen very well and much better than Firefox without any plug-ins.
The windows key on the screen panel works as the windows key on the keyboard.
Screen rotation is supported on the new gnome and disables the keyboard when the yoga is used as a tablet, side lock rotation button works to lock the screen in a certain rotation.



 What works Almost everything works great out of the box, there isn't many changes you need to do.
UbuntuGnome ships with gnome 3.24 and will boot with full resolution HiDPI and touch screen support enabled
