How to update the EP-1320 firmware
The EP-1320 Medieval updates its firmware over its USB-C port using teenage engineering's online update utility. Keeping the firmware current matters because updates regularly fix bugs that can cause file-system issues. This guide walks through what you need, the update steps, and how to recover if you hit an error code afterward.
What you need
Before you start, gather a couple of things so the update runs cleanly over the DATA port.
- A USB-C cable (5V, minimum 1A, a quality USB-IF compliant cable is recommended)
- A computer with internet access
Update the firmware
The actual update happens in teenage engineering's online update utility, not on the device itself. Connect over the DATA USB-C port and let the utility guide you.
- 1
Connect your EP-1320 to your computer using a USB-C cable.
- 2
Go to the firmware update utility at teenage.engineering. The manual refers to this as the update utility but does not list a specific URL in the available documentation.
- 3
Follow the on-screen instructions in the update utility to install the latest firmware.
Keep your device up to date, as teenage engineering notes that firmware updates regularly fix bugs that can cause file-system issues.
Fix E.04 and E.05 errors after an update
If your device shows an error code like E.04 or E.05 after an update, you may need to format the file system.
- Power the device off.
- Hold ALTERO (shift) and ERADO (erase) while powering on to format the file system.
Note that this erases all user content, so back up your samples first using the EP Sample Tool at teenage.engineering/apps/ep-sample-tool.
Always back up your samples before formatting the file system, since the format wipes everything stored on the device.
