Hi Sir
We did some experiments to connect AM3352 GPIO1_9 to ground via the resistor.
and the result is listed as below
10Ω：v=0.56V，I=50.99mA
50Ω：v=1.78V，I=33.4mA
100Ω：v=2.36V，I=22.99mA
1KΩ：v=3.2V，I=3.319mA
the spec defined the max. current of GPIO1_9 is 6mA
It seems GPIO doesn't have the current limit feature or could you advise what is wrong?
