== Tips ==
Use this space to share tips about using the FRI2. If you didn't find it in the README and it took you longer than 5 minutes to figure it out, consider placing it here and we can work it into the README as appropriate.

=== Unable to view HDMI output on your monitor ===

Some HDMI monitors do not appear to work with the HDMI output from the FRI2. Which displays work and which do not can be unpredictable; it may even be the case that individual monitors of the same make and model may work while others may not.

As a workaround you can connect the FRI2 to the DVI connection on your monitor using an HDMI to DVI adapter.

=== Obtaining the ti_3410.fw file needed by ti_usb_3410_5052 ===

Debian (and perhaps other Linux distros) do not package ti_3410.fw (no, not even in lfirmware-linux-nonfree).     The following bash script will use git to obtain just the one file from kernel.org and move it to where "modprobe ti_usb_3410_5052" will find it:

   #!/bin/bash
   sudo apt-get install git
   git clone -n git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git --depth 1
   cd linux-firmware
   git checkout HEAD ti_3410.fw
   sudo cp -p ti_3410.fw /lib/firmware

The script is tested on Debian with 3.1.0 kernel and will need to be modified if your system uses RPM and/or does not follow the standard filesystem hierarchy.

Note that <b>Ubuntu and Fedora both package it</b> with the linux-firmware package and Ubuntu also includes it in the various linux-image packages.

== Known Issues ==
=== Warning at arch/x86/kernel/apic/ipi.c ===
 WARNING: at [...] linux-yocto-3.2.18+git1+5b4c9dc78b5ae607173cc3ddab9bce1b5f78129b_1+76dc683eccc46804729a76b9d2fd425ba540a483-r1/linux/arch/x86/kernel/apic/ipi.c:109 default_send_IPI_mask_logical+0xa4/0xe0()
 Hardware name: Fish River Island II
 empty IPI mask
 Modules linked in:
 Pid: 1, comm: swapper/0 Not tainted 3.2.18-yocto-standard #1
 Call Trace:

This appears to be a known issue with how IPIs are handled within the generic SMP infrastructure. A fix is being discussed on [https://lkml.org/lkml/2012/2/19/11 LKML], but the warning appears to be benign.
