  Hi,
  
  i just corrected a bug in teh loader coe that was updated for PI2, can you do a gill pull on logi-tools ? For the PI2, there are multiple things to do before eveyrthing works :
  
  1) to a clean in stall of latest logi-tools
  2) go in the logi-tools/logipi_loader directory
  3) do a  "make clean" followed by a "make PI_VER=PI2" and finally "sudo make install"
  4) got to the /boot directory of your PI, and edit the config.txt file
  5) add the line "device_tree=" to disable device_tree and reboot
  
  At this point everything should be working fine.
  
  Regards,
  
  Jonathan Piat

  Yes that worked fine. Can you update the readme on the GIT to include the above?

  I followed the instructions, but I am having problems getting Raspberry Pi 2 working with LOGi Pi2. The error I get is
  
  LOGI_LOADER VERSION : 0.1.0
  Compiled for LOGI-PI
  could not open I2C device : /dev/i2c-1!
  Cannot detect LOGI-PI with I2C_LOADER, switching to old bit-bang loader
  Board variant is LOGIPI_R1.0
  can't open /dev/mem
  Blink LED App *************************************************************************
  
  I'm using the latest image from the wiki logi_2015-02-16-raspbian-wheezy. I did a git pull to make sure I had the latest code for logi-tools.
  
  thanks

  DI you follow these instructions on the github :
  
  To enable SPI on latest raspbian distro, edit /boot/config.txt (as sudo) and add :

  dtparam=spi=on

  To enable I2C on latest raspbian distro, edit /boot/config.txt (as sudo )and add :

  dtparam=i2c_arm=on

  to the file.

  also edit /etc/modules (as sudo) and add the line :

  i2c-dev

  I used the image up on the wiki and double checked all of that. I saw the other thread and contacted element14 to get a replacement.

  I'm one more person who has this problem.   I'm running on an original Raspberry Pi, not a Pi2.

  
  

  I'm using the stock logi_2015-02-16-raspbian-wheezy.img

  i've done a git pull (it was up to date)
  

  I can see the right lines in /boot/config.txt  and /etc/modules

  I've make and installed the unified loader

  I've rebooted many times

  
  

  I still get:

  
  

  root@logipi:/home/pi/logi-apps/blink_led_app# /home/pi/logi-tools/unified_loader/logi_loader

  Compiled for LOGI-PI 

  could not open I2C device : /dev/i2c-1!

  Cannot detect LOGI-PI with I2C_LOADER, switching to old bit-bang loader 

  Board variant is LOGIPI_R1.0 

  
  

  That is, I can't open /dev/i2c-1 so nothing else stands a chance of working.

  
  

  I'm disappointed, I was looking forward to playing with this but instead I've spent a whole day of holiday trying to get it to run "hello world" (and I've scheduled much mroe time to learn Verilog/VHDL).
