## Troubleshooting

### The firmware folder name has space (blank)

<figure><img src="https://3309772875-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FnikHUDUd2JXqkOsnOi7l%2Fuploads%2FpjOl9ejPZB2Wllr8L8Oq%2Fimage_2022-10-21_142836789.png?alt=media&#x26;token=ed47fc85-086f-426e-8c63-5bed6102f71a" alt=""><figcaption></figcaption></figure>

This problem will be fixed when saving the folder where the path has no spaces or special characters.

Example: C:\Users\Admin\Desktop\PixySM300\_SoM\_Firmware\Pixy\_SM\_v2.1.0.38 (no spaces and special characters)

### Lost file setting.json

This error will be fixed by extracting the firmware again and not moving the files contained in the folder after decompression.

During the loading process, if there are other errors, please capture the error code and contact our support team by email: <support@gremsy.com>
