# Troubleshooting download problems
|
|
|
|
If you're having trouble getting your code onto the EV3 Brick, try these steps to see if you can fix the problem.
|
|
|
|
## Check your **@drivename@** firmware
|
|
|
|
MakeCode needs a firmware version of **1.10E** or higher installed on your brick.
|
|
|
|
### ~hint
|
|
|
|
Firmware is the software that runs all the basic operations on your EV3 Brick. Your programs and the firmware work together to make the EV3 Brick do all things you want it to. Your EV3 Brick comes with firmware pre-installed, but it may need to be updated to work properly with MakeCode.
|
|
|
|
### ~
|
|
|
|
To check the the firmware version on your EV3 Brick:
|
|
|
|
1. Go to the **Settings** menu (it's under the wrench tool symbol)
|
|
2. Select **Brick Info** and press ENTER
|
|
|
|
|
|
|
|
3. Check the version number under **Brick FW:**
|
|
|
|
|
|
|
|
If you can't find the **Brick Info** or you see that the version is less than **1.10E**, **you need to upgrade your firmware**.
|
|
|
|
## Upgrade your **@drivename@**
|
|
|
|
If your a firmware version level is less than **1.10E**, you need to install an upgraded version. You can upgrade the firmware with the **EV3 Lab** or **EV3 Programming** software. Also, you can do a manual upgrade by downloading the firmware install file. See the [Firmware Update](https://education.lego.com/en-us/support/mindstorms-ev3/firmware-update) support page to learn about the upgrade process.

**Recommended:** Upgrade with the **[EV3 Device Manager](https://ev3manager.education.lego.com/)**

## Can I see the **@drivename@** drive on my computer?
|
|
|
|
When your EV3 Brick is connected to your computer, you should see a new drive called **@drivename@** attached.
|
|
|
|
On Windows, it looks like this in Explorer:
|
|
|
|
|
|
|
|
If you don't see the **@drivename@** drive, make sure your brick is powered on and check that your USB connection is good.
|
|
|
|
## The display on the EV3 Brick is blank
|
|
|
|
Make sure your EV3 Brick is charged and powered on. If your it doesn't turn on, find the charger and plug it into wall power, then connect it to your EV3 Brick. Does it turn on and start up?
|
|
|
|
## I still can't see my @drivename@ drive
|
|
|
|
Make sure that one end of your USB cable is firmly inserted into a USB port on the computer and the other end is connected to the EV3 Brick. If you still can't see the **@drivename@** drive, try a different port on the computer. If that doesn't work then maybe your cable is faulty or you need to reset the EV3 Brick.
|
|
|
|
## How do I reset my EV3 Brick?
|
|
|
|
If you think your USB connection is good and you still can't see your **@drivename@** drive, try giving the EV3 Brick a reset. You can follow these steps to reset:
|
|
|
|
1. Using a finger from one hand, press the **Back** button. Keep holding it.
|
|
2. With your other hand, use two fingers to hold down both the **Left** button and the **Center** button. You hold these at the same time while you're still pressing the **Back** button.
|
|
3. Now, release your finger from the **Back** button.
|
|
4. When the EV3 Brick says "Starting.." you can let go of the **Left** and **Enter** buttons.
