I’m trying to connect a board containing the MAX98357A chip (I2S decoder and analog audio amplifier) to the I2S4 output of the 40-pin header connector pins (pins 12, 35, 38 and 40). I’m sure the hardware electrical connections are correct and my board is in good condition. I used the Jetson-io.py software to correctly configure the I2S4 pins for their functions. Still, I can’t enable this interface in any way. How should I proceed?
Hi,
Before we can help you with proper suggestion to fix this issue, can you help with the below clarification.
As you enabled the I2S4 from jetson-io tool, do you see I2S4 clocks (FS, SCLK) output on oscilloscope from the Jetson nano board with I2S4 in Master mode?.
*I can’t enable this interface in any way. How should I proceed?
Can you provide more info here like the steps you tried to enable this interface, how you concluded the interface is not enabled.
