Author: Petr Porazil

File:Jt usb5.pdf

Adapter is compatible with standard 20 pin ARM JTAG connector as well as provides reduced 10 pin connector used on PiKRON's LPC17xx, LPC21xx, i.MX and other boards.

Permit access to usb as non-root user

in /etc/udev/rules.d add file 45-ftdi-libftdi.rules with following content:

ACTION!="add", SUBSYSTEM!="usb_device", GOTO="kcontrol_rules_end"
ATTR(idProduct)=="bcd9", ATTR(idVendor)=="0403", MODE:="666"
LABEL="kcontrol_rules_end"

Values are checked on Stellaris board and Ubuntu 10.10. Then reload rules

:/# initctl reload-configuration udev

and reconnect your hardware.
