Sorry but this does not work. Here are the steps and what happened...
I did finally get it working though and have included the steps below that I used. Someone else may be able to use them if they run into this issue.
Thanks,
George
1. Download the latest f/w from here: http://e2e.ti.com/support/data_converters/audio_converters/f/64/t/218025.aspx.
I downloaded this file
2. Remove USB cable.
done
3. Short TP1 and TP2.
done
4. Insert USB cable. Wait for 5 seconds.
done. I hear 3 low frequency beeps from Windows. Not the usual device found sound. No message pops up. In Device Manager under Other devices, Unknown appears. Under Universal Serial Bus controllers, Unknown Device appears.
5. Remove TP1 to TP2 short. The Windows device manager should show a TI DFU device under USB devices. If the device has an exclamation mark or a new device window pops-up, install the DFU driver found in the link in step 1.
When I remove the short, nothing happens. The two unknown devices listed above still remain.
6. Run DFUTEST.exe. If a "No DFU devices found" window appears, then that means that steps 2-5 were not followed properly. Close DFUTEST.exe and repeat steps 2-6.
I repeat the steps exactly as stated and nothing changes so I stopped at this step. DFUTEST reports "No DFU devices found. Set EEPROM's I2C Address to 1010xxx and restart this program(xxx is anything different than 000)". I see no way to change the address.
To get things going again, I clicked on the properties for the Other devices, Unknown and updated the driver, setting the folder to dfu_driver. This installed the DFU driver.
I started over at step 2. When I clicked Program EVM and selected the bin files I get a message that says "Set EEPROM's I2C Address to 1010000b". I clicked OK and got a couple more message boxes, one told me download was successful and resetting device. Then I get the "No DFU devices found. Set EEPROM's I2C Address to 1010xxx and restart this program(xxx is anything different than 000)" message again. If I run DFUTEST again, I get that same message. However if I run AIC3256EVM-U CS it finds the device at address 0x30, the USB LED is green and the sampling rate is now 44100.
