The firmware for the Analog EVM Controller must be upgraded for the first time before using the software. A jumper must be modified, and the USB cable must be connected to the XDS110 port of the Analog EVM Controller to download firmware. The firmware can be programmed to the Analog EVM Controller using the online tool UniFlash. This link is also provided on the Setup page of the GUI. The firmware bin file can be found at <Download Directory>\TPL1401EVM_1.0.1_installer_win\install_image_TPL1401EVM\TPL1401EVM\firmware\acctrl.0.3.0.3b.bin after unzipping the file install_image_TPL1401EVM.zip.
