This indicates that the firmware on the board is not correct.
Please set the jumper and switch as per my previous post and attach the EVM to the PC. If it still enumerates as a TI DFU device, perform the following:
* locate the AIC3204 GUI software on your PC. The software has a USBfirmware folder. Open this folder and install the DFUUSB driver from this folder (as per standard Windows driver procedure).
* If the DFU driver is installed correctly, launch DFUTEST.exe from the USBfirmware folder. There should not be an error message. If there is an error message, make sure that the device enumerated as a TI DFU device and that the driver is installed.
* Click the Program EVM button. Select DFUEE.bin from the USBfirmware\image folder and follow the instructions on the screen.
* Select USB-miniEVM0204_441KHZ.bin (or any other sampling rate) and follow the instructions on the screen.
Once this procedure is completed, the GUI should recognize the EVM.
