GPT input capture in QT

david_lim — Tue, 28 Jan 2020 07:54:40 GMT

I am using imx7d for my development and one of the motor speed frequency feedback by pulse is attached to gpt2.capture1.

In the imx7s.dtsi, the gpt2 is configured as below:

I have added the patchwork from the below link:

https://community.nxp.com/external-link.jspa?url=https%3A%2F%2Fpatchwork.kernel.org%2Fpatch%2F9177095%2F

But the problem is, i do not know where should i use the mxc_request_input_capture.

I would want to configure these in QT and to be able to get the interrupt inside the QT.

But from the source from /opt/fslc-x11/2.5/environment-setup-armv7at2hf-neon-fslc-linux-gnueabi, inside doesn't have the required headers for me to do so in QT.

Do you have any example on how should I get the interrupt of the GPT?

Hi David

one can try with official nxp linux from source.codeaurora.org/external/imx/linux-imx repository
linux-imx - i.MX Linux kernel
Linux 4.19.35_1.1.0 Documentation

Also some gpt examples can be found in

FreeRTOS_iMX7D_1.0.1_WIN
