Can you explain the procedure to change the drive strength of Jetson nano SD Clock pin in terms of changing Magnitude and Rise / Fall time and frequency. and if possible can you explain what is the value for <0xa> in device tree and by changing the value what the will be the reflection.
either in magnitude or Rise/Fall time.
nvidia,pull-down-strength = <0xa>;
nvidia,pull-up-strength = <0xa>;
Welcome to the NVIDIA Developer forums. Your post should go in the Jetson Nano category for support. I will move it there for you.
there’re values with its offsets, please tweak the drive strength as following,
0x1 + 1 to drive strength 0x2 + 2 to drive strength 0x3 ... 0xF + 15 to drive strength
on the other hand
0x7F -1 to drive strength 0x7E -2 to drive strength ... 0x70 -15 to drive strength
Hello jerry thanks for your reply
Can you please explain what the drive strength states? whether it is Output impedance or Rise / Fall time.
you may access to pinmux spreadsheets to review the pin configuration.
