From SSH


(if lirc is executing, stop it with
 sudo /etc/init.d/lirc stop)

irrecord -d /dev/lirc0 /home/pi/mi_mando_tv.conf

irrecord -f -d /dev/lirc0 /home/pi/my_nevir_tv.conf
(-f for raw mode; it was required for my tv handler. it writes more hex codes for each key) 
(irrecord will ask to press many buttons, have patience because it is a quite boring process, after it it will ask for KEY names, enter a previous keyname, press enter, press key in IR handler.)

cp my_nevir_tv.conf lircd.conf


From RaspBMC/Openelect GUI(GUI Graphical User Interface)

 If using RaspBMC, from Menu enter in "Raspbmc Settings", "IR Remote"
Then, verify following options.
"Enable GPIO TSOP IR Receiver" must be enabled
"GPIO TSOPremote profile"=Custom
and it will detect a new lircd.conf file and will ask for reboot. Select "Yes"


From RaspBMC/Openelect GUI(GUI Graphical User Interface)

 If using RaspBMC, from Menu enter in "Raspbmc Settings", "IR Remote"

From OSMC(GUI Graphical User Interface)

By default, it is enabled
Verify from:
"Pi Config"; "Hardware support";
Enable LIRC GPIO support=yes
gpio_in_pin=18

From  "Remotes", "Browse" and load a config file

Deploying OS on Rasperry - partitions, filesystems,...

From my point of view, the default raspberry OS images or the installation script, lacks of some useful features, such as:

• Deployment from an image

• A bigger fat partition (useful for data exchange; it able to insert this SD in a Windows computer and copy files there)
• Additional partition for  data  (having system and data separated, it is possible to have smaller backups containing only system partition)

• Deployment from a installation script

• OSMC (installation script, creates a
•      a 1st partition of 242MB FAT32-LBA
•      a 2nd partition using the rest of the SD.

So, we can improve the default deployment with the following solutions:

1. Deploy the standard image on a bigger SD card (default)
2. Deploy the standard image on a bigger SD card and resize partitions (gparted)
3. Manual method 1
4. Manual method 2
1. Deploy standard image on a bigger SD card
2. Resize ext partition (decrease from begining) in order to free space after the fat32 partition
3. Copy or pack (tar) files from fat32 partition
4. Delete fat partition
5. Create a new fat32 (lba) partition with desired size
6. Paste, untar files on fat32 partition

Some examples of a "better" partition

XBMC

SD 8GB
fat32 1GB(boot+media)
ext4 7GB(system+media)

SD 16GB 
fat32 8GB(boot+media)
ext4 8GB(system+media)

Raspbian

SD 16GB 
fat32 1GB(boot+media)
ext4 7GB(system)
ext4  8GB(data)

Partition backups on images

Backups to image can be done at partition level, using dd command or graphical tool (i.e Disks in Ubuntu)
To restore an image containing a partition, you have to create a partition on destination disk.
If you are using "Disks" and image size and destination partition have not the same size, it will alert you but don't worry it works.

Checking content of images

sudo fdisk /media/midisco/raspberry_cosas/OpenELEC-RPi.arm-4.0.5.img

Resizing OS from an image

Gparted

In theory with gparted it is possible to resize fat and ext partitions but it

sometimes can have problems resizing a  fat32 filesystem, it means that partition have desired size but filesystem and available space still having the original size.
-usually works fine with ext2, ext3 partitions

Manual method for fat32 partition

dd partition1(fat32) on a disk

Copy or pack (tar) files from fat32 partition
Delete partition
Create a new fat32 (lba) partition with desired size
Paste, untar files 

Accessing from Windows to Linux Filesystem

Use a file explorer, i.e Linux reader from diskinternals

Tools:Windows Software
Ms. Windows is not the best environment to work with disks, filesystems etc.. but using the following apps we can do most of the tasks without the need of rebooting a Windows computer.

Win32DiskImager.exe (GPL)
Linux Reader (Diskinternals)
EaseUS Partition Master (EaseUS)

There are better software for Windows\DOS and Linux but at least the previous are gratis

1. Uncompress downloaded file
2. Identify SD card device (i.e /dev/mmblkxx) (1)
3. Format/remove partition from SD card. Disks or Fdisk (2)
4. Applying image to SD
•  sudo dd if=/path/sd.img of=/dev/mmcblk0 (3)
•  /path/ mounter folder where image is placed
5. Boot Raspberry with SD
• (Raspbmc will do some actions over SD, Sucha as partition resizing etc)
6. (optional) From PC, resize/create partitions
• (i.e with gparted) (4)
• Create a fat32 partition
• Copy multimedia to SD

(1) use Disks, dmesg, ...
(2) if there is problem try with a different card reader, usb to SD adaptor,..
(3) Use dd command or restore image from Disks on GUI, wait because it can take sometime and there is not a progress bar
(4) gparted recommended, but other software could done this action
