You can use your
CTT SensorStation to burn a new operating system onto the compute module using a micro USB cable attached to your computer. Here is an article on raspbian’s website with general instructions: Flashing the Compute Module eMMC. This page will summarize the steps needed to burn a New CTT SensorStation image to your compute module using the SensorStation hardware.
While CTT offers many over-the-air updates to your
CTT SensorStation sometimes you just need a fresh start, or maybe you haven’t been incrementally updating the source code and want to do so after a full stable release. You’ve found the right place to learn how!

You will need drivers for your computer to recognize the module as a new drive, and software to burn new images to disk.
Linux / MAC users will have to clone the rpiboot source code, compile and run the rpiboot.exe file that is generated. Detailed instructions for Linux here.
For Mac, follow these directions:
Homebrew, which is a package installer for Mac.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
git clone --depth=1 https://github.com/raspberrypi/usbboot cd usbboot
Then install the libusb libraries:
brew install libusb
Then make the rpiboot installer:
Then run rpiboot:
At this point you should see a message in your terminal that says something to the effect of:
Waiting for BCM2835/6/7/2711...
This indicates that the USB port has been opened, and your computer is waiting to see a Raspberry Pi on that port. Now complete Steps 1 and 2 below, and skip steps 3 and 4.
