I have two TLV320AIC3254EVM-K evm's with the same results. I have to use a Windows XP PC to load the evm firmware below:
Audio Converter Firmware (TAS1020B) V0304 (Rev. B) – SLAC563B.ZIP (684KB)
I can not load the evm firmware on a Windows 7 or 10 PC.
Once I have the the 3.04 Firmware loaded (using a Windows XP PC) I can connect the evm to a Windows 7 or 10 PC and run Control Software (v1.2.1) (Rev. D) and get the same result. See Below:
I'm assuming there is no communication to the I2C (AIC3254). If I run the Control Software on a Windows XP PC it works correctly. I get the same results with Evm Firmware 2.03.
The evm will work with Pure Path Studio v5.95 on Windows 7, I can connect and Download Code to the device on the evm. The only issue is Control Software (v1.2.1) (Rev. D).
What is my problem? I need to be able to use the TLV320AIC3254EVM-K with newer OS's preferably Windows 10. My company frowns on the use of Windows XP and they are getting scarce.
