Using Xavier GPIOs for control path

Autonomous Machines Jetson & Embedded Systems Jetson AGX Xavier
#1

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:

  1. What is the maximum supported GPIO rate?
  2. Can sync the write to the clock and data to be at the exact same time somehow?

Regards,
Ron

Sorr for the late response, have you found the answer you need?

No,
But the GPIO max rate is not good enough for me.

Regards,
Ron

hello ron.persky,

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