I have a series of questions regarding accessing GPIO on Qnx.
1> To enable gpio’s making changes to device tree (dtsi) files. And flash.
But how do it via pinmux file ?..
We can generate dtsi files from Generate DT options in excel sheet. But how to generate multiple .dtsi files specific to each components on SOC(such as UART, SPI, GPIO etc).
We don’t have gpio.h files in QNX include ?
Then to access gpio
Do I have to write program manually specifying the address of gpio followed by opening/closing fd ?
Or we have gpio built-in libraries in QNX similar to that of gpio.h in C or import gpio as in python in Linux platform ?
