How to revive a MC57xxPSIA board

The MC57xxPSIA is a board used to interface, configure and control the TAS57xx family of digital audio amplifiers.

The Firmware of the MC57xxPSIA may get corrupted, resulting in Windows not recognizing the board. 

Follow the next steps to reprogram the MC57xxPSIA Board. the required files are included in the attached zip file. 

1) Remove the jumper from the board labeled A0

2)  Short SDA and SCL lines by shorting the EEPROM SDA and SCL pins (U1, pins 5 and 6).

3)  Connect the EVM board to the USB socket.

4)  After 5 seconds, remove the short.

5) Run the DFUTEST.exe from the unzipped folder

6) Click 'Program USBMODEVM' 

7) Select DFUEE.bin file

8) Program will popup message box about (jumper). Replace jumper across A0, click OK

9) Device will program, WAIT for the device to detach & reattach.

10) Find the driver (if necessary) in the extracted directory from the zip. This step is needed only the OS asks for the driver.

11) Popup Device successfully reset, Click OK

12) Popup Device program successfully, Click OK

13) Popup for new filename, select EEPROM.bin

14) Device will program, WAIT for the device to detach & reattach.

15) Find the driver if necessary in the extracted directory from the zip

16) Popup Device successfully reset, Click OK

17) Popup Device program successfully, Click OK

18) Open Device Manager

19) Click on" new device connected" and update Driver (This step is needed for only few OS).

The new device should show up as Human Interface Device in the USB Device Manager

How to Revive a USB Audio EVM

Applies to:

TLV320AIC3254EVM-K
TLV320AIC3254EVM-U
TLV320AIC3204EVM-K
TLV320AIC3253EVM-K
TLV320AIC3256EVM-U

PCM3070RHBEVM-K 
TLV320AIC3212EVM-U
TLV320AIC3262EVM-U 
TLV320AIC3268EVM-U


IMPORTANT: Before proceeding, ensure that the jumpers are set to their default positions. Refer to the EVM User Guide by clicking the link of the appropriate EVM above.

If the USB Active LED does not lit on the EVM and does not enumerate as a USB Audio device, follow these steps:

1. Download your USBfirmware files:

For TLV320AIC/DAC/ADC EVMs: http://www.ti.com/lit/zip/slac563.

For TAS/PCM EVMs and PurePath Console Motherboard: http://www.ti.com/lit/zip/sloc305.

2. Remove the USB cable from the board.

3. Short SDA and SCL lines by shorting the EEPROM SDA and SCL pins (not the test points).

4. Connect the EVM board to the USB socket.

5. After 5 seconds, remove the short.

6. A 'Found new Hardware' wizard will appear. The driver is in under "dfu_driver\" inside the USBfirmware files obtained above.

7. Run DFUTEST.exe. This is found inside the USBfirmware files obtained above. If the message below appears, repeat steps 2-6.

8. Click the Program EVM button. Browse for the DFUEE.bin file located in the "image\" directory. Click Open.

9. The following message will appear. Click OK.

  

10. A "Download completed" message will appear. Click OK.

11. A "Device was succesfully reset. Please..." message will appear. Wait 2-3 seconds before clicking OK. If a "Found new hardware wizard appears, install the DFU driver as explained in Step 6.

12. A "Detach call succeeded. Please..." message will appear. Wait 2-3 seconds before clicking OK. If a "Found new hardware wizard appears, install the DFU driver as explained in Step 6.

13. Browse for the desired firmware image file (e.g. USB-xxxx_441KHZ.bin) located in the "image\" directory. Click Open.

14. Click OK for the next two windows. The last window will look like the one below.

 Programming Complete

15. Click OK and close the DFUTEST program.

16. Run "remove-miniEVM.exe" as administrator (right click option). This is found inside the USBfirmware files obtained above.

17. Remove and re-connect the USB cable.

18. The EVM is now ready for use.

Music won't play with USB streaming

There are several reasons that music won't play on an EVM for USB streaming. Let's address a couple of them here. Note that this page will apply to essentially any device using the TAS1020B USB to I2C/I2S device.

Always refer to the EVM's user's guide as an initial point of reference for configuring the device

1) Check that the EVM is selected as the default device.

To do this, open up control panel and select "Sound"

Next, right click the USB-AudioEVM and select "Set as Default Device"

Now check to see if music is playing.

2) If you get the error "Windows Media Player encourtered a problem while playing this file."

or in YouTube "An error occurred, please try again later. Learn More"

 To resolve this go to control panel -> sound

right click USB-AudioEVM and select "properties"

Then select the "Advanced" tab

Next try to change the sample rate from 48000 Hz to 44100 Hz or vice versa.

Now check to see if music can play.

3) Remember that register settings for audio converters are all volatile memory, so be sure to use the GUI or I2C script after every power cycle as many devices do not play music unless they are programmed first.

TAS1020B Firmware Update Procedure

Applies to:

PurePath Console MotherBoard (Rev D)

The TAS5766 App and TAS5766_Dual App in PPC3 require a PPCMB (PurePath Console MotherBoard) that can support 48KHz sample rate.  If you have a PPCBM (Rev D) whose firmware only supports 44.1KHz sample rate, you have to update its firmware.  

Follow the steps in Appendix D of the document below to update the firmware.  

3276.TAS1020B Firmware Update Procedure.pdf

All the software required can be downloaded here: http://www.ti.com/lit/zip/sloc305.

Here is one important trick that you should be aware of. The very first step is to short SCL and SDA pins of the EEPROM to ground.  Usually what I do is to use a tweezer to short Pin 5&6 of EP1 to ground.  Be careful when you do this!
