Use short wires, esp. if you are not adding the 0.1{{micro}}F capacitor between ground and vcc as close as possible to the chip

[http://www.raspberrypi.org/introducing-raspberry-pi-model-b-plus/ newer Raspberry Pi model B+] and Raspberry Pi model A+ both use same pinout for the first 26 pinheaders as the previous nonplus model, so it should work on that as well.


=== Installation ===

==== Installing Raspbian ====
Run win32diskimage (if you use linux you can use dd)<br />
[[File:Win32DiskImager.png]]
# In "Image file" select the downloaded and decompressed Raspbian image (''2013-09-25-wheezy-raspbian.img'' at the time of this writing)
# In "Device" select the drive where the SD memory is.
# Select "Write".
After finished writing, put the SD card in the Raspberry Pi and power it up by inserting the USB cable.

==== Remote Shell into Raspbian ====
Two minutes after booting up the Raspberry Pi, run Putty.<br />
[[File:Putty.png]]
# In Host Name put: raspberrypi<br />If this doesn't works properly, go to the router, find the IP assigned to your Raspberry Pi and use that instead,
# Select SSH (or Raspberry and Putty support TTL https://learn.adafruit.com/adafruits-raspberry-pi-lesson-5-using-a-console-cable/overview) 
# Select Open

==== Installing Application ====
It will request a Login. According Raspbian the user is "pi" and the password "raspberry" (Both without quotes).

Insert the following commands:
{{keyboard|content=
sudo -s
cd /bin
wget http://jaicrab.org/Ps4/Tools/JAISPI/jaispi
chmod +x jaispi
echo "#blacklist spi-bcm2708" > /etc/modprobe.d/raspi-blacklist.conf
echo "blacklist i2c-bcm2708" >> /etc/modprobe.d/raspi-blacklist.conf
reboot
}}

Installation is complete. By Putty you can access the Raspberry Pi. To run the command jaispi you need to be root (sudo-s):
{{keyboard|content=
# sudo -s
# Jaispi -i / dev/spidev0.0
}}

=== Options ===
  -i /dev/spidevX.X             Get ID from flash
  -r file.bin /dev/spidevX.X    Read entire flash to file
  -e /dev/spidevX.X             Erase entire flash
  -p file.bin /dev/spidevX.X    Only write blocks differences from file
  -v file.bin /dev/spidevX.X    Verify blocks with file
==== Get ID ====
-i: Displays information of the flash.
 #jaispi -i /dev/spidev0.0
 JaiSpi v1.0
 ID:  0xC22019 MX25L25635
==== Read ====
-r: Makes a full dump of the flash (Average time: 35sec)
 #jaispi -r DUMP.bin /dev/spidev0.0
 JaiSpi v1.0
 ID:  0xC22019 MX25L25635
 Reading...
 0x02000000
 Done!
==== Erase ====
-e: Clears all flash (Average time: 1min, 30sec)
 #jaispi -e /dev/spidev0.0
 JaiSpi v1.0
 ID:  0xC22019 MX25L25635
 Erasing blocks...
 Done!
==== Program ====
-p: Write to flash only the changed sectors (Average time: 1min 30sec)
 #jaispi -p Base.bin /dev/spidev0.0
 JaiSpi v1.0
 ID:  0xC22019 MX25L25635
 Starting...
 0x02000000 -> 8192 Sectors written
 Done!
==== Verify ====
-v: Compares the flash contents with a file in PC (Average time: 35sec)
 #jaispi -v Base.bin /dev/spidev0.0
 JaiSpi v1.0
 ID:  0xC22019 MX25L25635
 Checking...
 0x02000000 -> 0 Different sectors
 Done!
