 +There is no dedicated Blackfin STAMP evaluation board for the ADAU1373. During test and driver development we used the [[adi>EVAL-ADAU1373]] board.
 +
 +It can be easily wired to the Blackfin STAMP SPORT header.

-===== Adding Kernel Support - As a module ===== +===== Kernel configuration =====
-Skip this section if you want to build the driver into the kernel directly. +
-To add support for codec ADAU1373 to the kernel build system, a few things must be enabled properly for things to work.The configuration is as following:     +
  
 <code> <code>
-Linux Kernel Configuration +Device Drivers  ---> 
-  Device Drivers  --->  +[*] I2C support  ---> 
-    Sound  --->  +[*]   I2C Hardware Bus support  ---> 
-      <M> Sound card support +***     I2C system bus drivers (mostly embedded / system-on-chip) *** 
-        Advanced Linux Sound Architecture  ---> +<*>       Blackfin TWI I2C support 
-          <M> Advanced Linux Sound Architecture +(100)     Blackfin TWI I2C clock (kHz)
-          < > Sequencer support +
-          <M> OSS Mixer API  +
-          <M> OSS PCM (digital audio) API +
-        System on Chip audio support  ---> +
-            <M> ALSA for SoC audio support +
-            <M> SoC I2S Audio for the ADI BF5xx chip  +
-            <M> SoC ADAU1373 Audio support  +
-            < > SoC AC97 Audio support for BF5xx  +
-            (0) Set a SPORT for Sound chip+
 </code> </code>
  
-<note important> +Enable ALSA SoC evaluation board driver:
-I2C bus is used to configure the codec.  So, if the audio driver is built into kernel, the I2c driver is also built into kernel automatically.  But if the audio driver is built as module, then make sure that the I2C driver is loaded before the audio module.   +
-</note> +
 <code> <code>
-Linux Kernel Configuration +Device Drivers  ---> 
-  Device Drivers  ---> +<M> Sound card support  ---> 
-    <*> I2C support  ---> +<M>   Advanced Linux Sound Architecture  ---> 
-      --- I2C support +<M>     ALSA for SoC audio support  ---> 
-          I2C Hardware Bus Support ---> +<M>       Support for the EVAL-ADAU1373 boards on Blackfin eval boards
-            <*> Blackfin TWI I2C support  +
 </code> </code>
  
-Doing this will create modules (outside the kernel). The modules will be inserted automatically when it is needed. You can also build sound driver into kernel.+===== Hardware configuration =====
  
 +Connect the STAMP SPORT 0 port (P6) to the EVAL-ADAU1373 J23 and J28 headers.
  
-==== Testing the built in kernel driver ====+Note that the SPORT has separate signals for the capture and playback clocks, while the ADAU1373 uses the same clock signals for both, so the EVAL-ADU1373 clock signal pins need to be connected to two STAMP pins each.
  
-If audio is configured as modules, skip this section. If audio is built into kernel and you have booted the kernel, there are a few things to check to ensure audio is working:+^ STAMP pin ^ EVAL-ADAU1373 pin ^ Function ^ 
 +| P6-26 (SPORT 0 - PJ2_SCL) | J23-1 | I2C SCL | 
 +| P6-24 (SPORT 0 - PJ3_SDA) | J23-3 | I2C SDA | 
 +| P6-6  (SPORT 0 - PJ9_TSCLK0), P6-16 (SPORT 0 - PJ6_RSCLK0) | J28-6 (A_BCLK) | BCLK | 
 +| P6-11 (SPORT 0 - PJ10_TFS0), P6-7 (SPORT 0 - PJ7_RFS0) | J28-8 (A_LRC) | LRCLK | 
 +| P6-14 (SPORT 0 - PJ11_DT0PRI | J28-10 (A_DACDAT) | Playback data | 
 +| P6-8  (SPORT 0 - PJ8_DR0PRI) | J28-12 (A_ADCDAT) | Captrue data | 
 +| P6-33 | J28-1 | GND |
  
-  - Check the boot messages to see if you have booted the correct kernel. During kernel boot, it should print out: <code> 
-Advanced Linux Sound Architecture Driver Version 1.0.12rc1 (Thu Jun 22 13:55:50 2006 UTC).
