Hello Team, Here are the environment details for the Jetson AGX Orin development kit that I’m using. JetPack version: 5.0.2 L4T Kernel: R35.1 Pinmux sheet downloaded from the Nvidia download center for Orin. So, before approaching you, I attempted to modify the Pinmux settings based on my prior…

Hi, These methods you shared does not prove anything… For example, when you are doing (1), no matter what pinmux status you set before, this “export” and “set value” will lead the pinmux back to gpio. Thus, no matter what you set before, maybe it is really in SFIO mode already. But it will be ba…

Flashed the Orin Dev Kit using the command “sudo./flash.sh jetson-agx-orin-devkit mmcblk0p1”. However, the Orin kit does not reflect the modified pins. Have you checked the flash log from above step and confirm your pinmux dtsi file is really getting flashed?

Hello Wayne, Thank you for your reply. Please find the attached flash log flash.log (83.3 KB) I can see that the bootloader file’s. dtsi file was copied. copying pinmux_config(/home/parashuram/nvidia/nvidia_sdk/JetPack_5.0.2_Linux_JETSON_AGX_ORIN_TARGETS/Linux_for_Tegra/bootloader/t186ref/BCT/teg…

Wayne, To make Pinmux changes, I followed the steps listed below. Downloaded the Pinmux spreadsheet from the Nvidia download center. Changed GPIO pins to I2S2 pins in spreadsheet and generated DT files and replaced pinmux dtsi changes in Linux for Tegra/bootloader/t186ref/BCT/tegra234-mb1-bct…

Does your flash log tell you tegra234-mb1-bct-gpio-p3701-0000-a04.dtsi is getting flashed?

Hello Wayne, Pinmix changes are made in both files tegra234-mb1-bct-gpio-p3701-0000-a04.dtsi and tegra234-mb1-bct-gpio-p3701-0000.dtsi I can see that in the flash log this file is taking here copying pinmux_config(/home/parashuram/nvidia/nvidia_sdk/JetPack_5.0.2_Linux_JETSON_AGX_ORIN_TARGETS/Linu…

BTW, before going further, I have one thing to clarify here. It seems you didn’t get my point in previous comments. [image] The Pinmux modifications are not reflected in the Orin development kit Jetson AGX Orin What is your method to tell “pinmux does not take effect on m…

Hello Wayne, I have followed below steps to verify the pinmux changes. Exporting the gpio in /sys/class/gpio/export and validating the pin value and direction. verfiying with the cat /sys/kernel/debug/pinctrl/2430000.pinmux/pinconf-groups Is there any other method verify pinmux status please let…

What is your method to tell “pinmux does not take effect on my device”?
