Possible pin mis-label

[GarageDirt]

I am using MIMX RT1176 eval board.  In configuration tools (pins), LPADC1 for Signal A,1_0, the routed pin/signal is shown as [N13] GPIO_06 with Label as USB_OTG2_ID/U18[A2]/J9[10]/AUD_INT.  

On my board, if I put an analog signal into that pin(J9[10]), that signal is not converted.  However, if I put the signal into J9[9], the signal is converted as expected.  Maybe the the pins configuration table is wrong, or I am.

Hi,

I tested this by using lpadc_polling example of the SDK that uses J9[10] as input. As you can see in my results below the first conversions are with J9[10] floating, then I connected J9[10] to GND and I was able to see correct measurements. Please check my results and connections below.

Please test this and let me know your results.

Best regards,

Felipe
