This tutorial will demonstrate to you how to upload firmware to a new device.
Log in to AVH with your Arm user account. Log in to https://avh.arm.com/ If you do not have or need to create an Arm account register at https://developer.arm.com/
When logged in you land on the AVH Devices page. Click "CREATE DEVICE".
Click on the "Raspberry Pi 4" to select it. Then click "NEXT".
In this next step, you'll see a list of pre-configured examples/stock firmware or you can upload your own custom firmware. Either drag&drop your custom firmware into the "Drag file here" box or use the ‘browse’ option, navigate and select the desired custom firmware.
You will see the progress of your custom firmware uploading. This might take a while, depending on the size of custom firmware you’re uploading. Once the upload is complete, click "NEXT".
In the confirmation screen, click "CREATE DEVICE". You can update the default name and use advanced boot options if required.
The device will then be created. It takes a few moments...
