How Can Do Loopback for 32Bit I2S/TDM Mode

Question

Hi Team, 
 I would like to perform an I2S/TDM loopback test for 32-bit data. However, the current profile I am using with the FAST DSP processes only 24-bit data. 
 Is there a way to test a 32-bit loopback configuration? I have attached the profile for your reference. 7345.I2S_MASTER_SPT0_FDSP_2CH_32BIT_48000KHz_3.072MHz.zip

Hi Mastan, 
 
 Sorry but there is not possible way to do 32-bit data loopback configuration. You can configure the slot width of the serial port between 16, 24 and 32 bits. but the maximum word depth is 24 bits. In a typycal Left justified or I2S configuration, if your slot width is 32 and your word width is 24, the last 8 bits will be ignored.
