Hey all!
As you may have seen, there's been some significant improvement with respect to Running ROS on Gentoo in the past few months. As such, I've compiled a 64-Bit Raspberry Pi 3 image with the necessary ROS components pre-installed!
Link to the image is [here.](

Info:
====
OS:
------
```
turtlebot@burger ~ $ uname -a
Linux burger 4.9.40-v8+ #1 SMP PREEMPT Thu Aug 3 13:18:43 PDT 2017 aarch64 GNU/Linux
```
Partitions:
--------------
* `/boot`: 128M, vfat
* `swap`: 512 M
* `/`: 14 G, ext4
Compiler:
-------------
* GCC 6.4.0
* `CFLAGS="-march=armv8-a+crc -mtune=cortex-a53 -ftree-vectorize -O2 -pipe -fomit-frame-pointer"`
* `MAKEOPTS="-j2"`
* No `USE` flags are enabled, I left that to you
ROS:
---------
* kinetic, installed in `/opt/ros/kinetic`
* workspace in `~/catkin_ws`
Usage:
======
Not much needs to be adjusted (woot). you'll need to set up the wifi, however.
User/Password:
-----------------------
* username is "turtlebot"
* password is "turtlebot"
* root password is also "turtlebot"
* You may consider emerging `sudo`, if you want.
Wireless:
--------------
Edit the file `/etc/wpa_supplicant/wpa_supplicant.conf` as needed.
```
ctrl_interface=/run/wpa_supplicant
update_config=1
network={
ssid="network ssid"
psk="super secret password"
}
```
After the wireless is established, you should be able to ssh to the host `burger.local`.
ROS Setup:
-----------------
The only thing to change here (as usual) is the `ROS_MASTER_URI`. Just change this value, and you should be good to go!
What's Enabled?
--------------------------
* I know for a fact that the wireless is working.
* All turtlebot3 packages
* 64-bit mode
* Video acceleration (though, if you want to install a desktop, you should remove the line that says `gpu_mem` in the `/boot/config.txt` file.
**Note: I have not tried anything with bluetooth, so I would not assume it is functioning.**
Let me know if you run into any issues! This is certainly not restricted only to turtlebot3 people -- you can install most packages now through portage.
