I recently bought a Raspberry Pi B+ and a PN532 NFC/RFID controller breakout board - v1.6 for doing some experiments with NFC stickers/tags.
I try to follow this guide, Adafruit NFC/RFID on Raspberry Pi but I get stuck on step one in the link. I'm supposed to change /boot/cmdline.txt from:
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 $
to:
dwc_otg.lpm_enable=0 console=tty1 $
In my Raspberri Pi the cmdline.txt looks like this:
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p6 rootfstype=ext4 elevator=deadline rootwait
When I change cmdline.txt to what the guide suggests my Pi doesn't boot anymore and I'm forced to do reinstall the system, formatting the SD card and start all over again with NOOBS. Before reboot I've also done step two in the guide.
The Pi B+ has a fresh install of Raspbian from http://www.raspberrypi.org/downloads/. I've done sudo apt-get update and sudo apt-get upgrade and I've also installed Emacs and Synaptic. dmesg (before the changes suggested in the guide) gives me this if it is of any help:
