Hello Community,
I have a question about the pinout of the Apalis Evaluation board. There are several connectors on the board. For example: X2, X3, X4.
X2 consists of grounds, 3v3 and a lot of MXM3 pins. X3 consists of of jumpers between X2 and X4. X4 consists of GPIO0-GPIO8, PWM0-PWm4,CAN, and some more logic pins.
For example: If I want to use PWM 2, I search in the datasheets of the Apalis iMX6 and Evaluation Board for the Linux number and GPIOX_IOXX number.
For example. PWM 2 is MXM3_4 > GPIO1_IO01 > Linux number: 1. If I put my cable in X4.14 (PWM2) and have the jumper removed. The programm that I made for this PWM isn’t working. If I replace the jumper or use pin X2.14 It works.
Is this because the logic of X4 pins only works if a jumper is placed to connect X4 with X2? or is there an other way to use X4 pins?
It is not a problem for me to use X2 instead of X4 I’m just curious about it.
I am looking forward to hear your reaction
