Hi, I would like to use Jetson Xavier GPIOs as a control path to an external peripheral. For example, One GPIO will be the clock, and another GPIO will be the data. My questions are: What is the maximum supported GPIO rate? Can sync the write to the clock and data to be at the exact same time …

Using Xavier GPIOs for control path

hello ron.persky,

please refer to GPIO Bit-Bang Speed Increase - #23 by Bibek to configure axi_cbb clock rate to get better results.
