Firmware

To update the firmware, you need a Windows 10/11 64bit PC with Vivado and J-Link Software installed. We tested with Vivado 2024.1 and J-Link Software v8.10.

NOTE: If the sole purpose is to update the firmware, it is strongly recommended to use “Vivado Lab Edition”. ML Edition requires more than 60 GB of disk space for installation. Lab Edition requires about 6 GB of disk space.

NOTE: When using an old J-Link device, check “Install legacy USB Driver for J-Link”. For example, J-Link Plus V10 and earlier require a legacy USB Driver. (The version is written on the back of the J-Link Plus device.) For more details, refer to the Segger Wiki. If the device you are using has the WinUSB feature, the legacy USB Driver is not required.

First, connect the AUTD3 device and the PC with a XILINX Platform Cable and a J-Link 9-Pin Cortex-M Adapter attached to a J-Link Plus, and turn on the power of the AUTD3. Next, execute autd_firmware_writer.ps1 in the autd3-firmware from PowerShell and follow the instructions. The update takes a few minutes.
