3 Intrductin The NVIDIA Andrid Fry OS Supprt Pack fr Tegra 250 Develpment Kits prvides an update t earlier Andrid 2.2 (Fry) OS images fr the Tegra develpment kits.

4 Install as directed - Cnfigured fr Tegra devkit ADB cnnectins: See the NVIDIA Tegra Andrid Setup Guide at: Cnfigure the system t run ADB withut needing t prefix the adb cmmand with sud. Smetimes adb isn't in the rt PATH, meaning yu will need t set up the adb driver fr a device t run in yur user grup with prper permissins. Yu need t create and edit a new rules file that the usb driver will apply. The steps are: 1. Create and edit new file: 2. add as new line: sud gedit /etc/udev/rules.d/51-andrid.rules SUBSYSTEM=="usb", SYSFS{idVendr}=="0955", MODE="0666", GROUP="myname" Instead f 'myname' fr grup, use yur username, r ther grup yur username shares permissins with. Instead f 0955, replace with ther vendr ID if nt an NVIDIA bard. 3. clse editing and fix permissins: sud chmd a+r /etc/udev/rules.d/51-andrid.rules 4. replug yur device, and restart the server: adb kill-server adb devices Nte that sud is n lnger required.
