# Overview

> Install or update Qualcomm Linux on the IQ-9075 EVK, and decide whether you need to flash.

Before you develop on the IQ-9075 EVK, make sure it is running the latest Qualcomm Linux software. This page helps you decide whether to flash, then points you to the right flashing method.

<Danger>
  **Caution:** Flashing erases all data on the device. Back up anything important before you start.
</Danger>

## Which path should I take?

<Steps>
  <Step title="First time powering on this board?">
    We recommend flashing the latest Qualcomm Linux before you do anything else, so you start from a known, current image. Continue to **[Flash the software](#flash-the-software)** below.
  </Step>

  <Step title="Have you flashed this board before?">
    If you already flashed a recent Qualcomm Linux build, you can skip flashing. Go straight to [**Set up the device**](../set-up-the-device) and verify the software version there.
  </Step>

  <Step title="Can't verify the version, or the image is too old?">
    If the device won't boot to a serial console, or the version doesn't match what you expect, the image is likely missing or outdated. Come back here and flash the latest software.
  </Step>
