Hi, I'm working on iMX6ULL evaluation kit. We are using the Yocto Project.
I was trying to interface a heart rate sensor with the processor. I configured it as an IIO device and wrote a device driver for that. All functionalities are working fine. But I'm facing some timing issues in the system. I would like to Toggle one GPIO on arrival of ADC Ready interrupts. It takes 50 - 120 usec to toggle. Also, It follows different timings when the IIO trigger buffer is enabled. I need to reduce this timing to less than 10usec. For that, I would like to get more details about interrupt handling in IIO drivers. I would like to know why this time delay occurs. Thanks and Regards, Mathew K Tharakan
