I need to read an input signal into the agx on a gpio pin that may be switching at 15kHz. How do I accomplish this with python? Reading this link people have been able to achieve faster write speeds using mmap, this link says you can access mmap with Python. Can anyone advise me on how to achieve …

hello iandanielsooknanan,

you may check the clock tree, i.e. # cat /sys/kernel/debug/clk/clk_summary | grep axi_cbb
please check the pinmux file, such as tegra19x-mb1-pinmux-p2888-0000-p2822-0000.cfg for the address.
thanks
