I’m struggling to enable GPIO 7 as PWM8 and GPIO 14 as PWM 7 using the Jetson_Xavier_NX_Module_Pinmux_Configuration_Template in Release 32.4.1. The pins mentioned work as GPIOs, but I’m unable to configure them as PWMs. I tried doing this by replicating the process I used for a nano module which i…

Hi Sgamu, Waiting for your reply for almost 3 weeks. If you have any issue, please file a new topic. I will close this one.

Thank you. I am unfamiliar with the correct method for generating the cfg file. Could you please instruct me on how to do that? I was able to see GPIO14 work as a PWM, while I couldn’t see GPIO7 as a PWM. As a result, I copied the cfg settings of GPIO14 into GPIO7 in the tegra19x-mb1-pinmux-p3668-a…

I can’t answer all of your questions, but you will want to start with the PINMUX spreadsheet. Go here, log in, go there again since redirect does not work: https://developer.nvidia.com/embedded/downloads#?search=pinmux&tx=$product,jetson_xavier_nx You’ll need to enable macros. You’ll probably have…

Thanks, I know how to generate a device tree from the spreadsheet. In the first response @WayneWWW said I would need the cfg file instead of the dtb, so I was asking about how to generate the cfg file.

I could be wrong, but I am thinking you should be able to generate a cfg file via the PINMUX spreadsheet (not just a device tree).

Hi, After you create the dts files from spreadsheet, please check the README file under below path to use the python script to generate the new cfg file. Also, for xavier series platform, there is no u-boot. ~/nvidia/nvidia_sdk/JetPack_4.4_DP_Linux_DP_JETSON_XAVIER_NX/Linux_for_Tegra/kernel/pinmu…

Thanks for the instructions on how to generate the pinmux, gpio and padvoltage .cfg files. After trying again, I got the same result. GPIO14 works, but GPIO7 does not work. I modified the (tegra19x-mb1-pinmux-p3668-a01.cfg) by changing the values of GPIO7 to GPIO14 as shown below. The value for GP…

Here’s the dmesg: nvidia@nvidia-desktop:~$ dmesg [ 0.000000] Booting Linux on physical CPU 0x0 [ 0.000000] Linux version 4.9.140-tegra (root@tx1-dev2) (gcc version 7.3.1 20180425 [linaro-7.3-2018.05 revision d29120a424ecfbc167ef90065c0eeb7f91977701] (Linaro GCC 7.3-2018.05) ) #2 SMP PREEMPT…

Hi, Glad to hear GPIO14 can work now. We will investigate why GPIO7 cannot work. Similar issue seems happen on Nano too.

Hi sgamu, The registers you mentioned are not for the pins you are using: pinmux.0x0243d038 = 0x00000410; # gp_pwm2_px2: gp, tristate-enable, input-disable, lpdr-disable but the value of GPIO7 is: pinmux.0x0243d030 = 0x00000415; # gp_pwm3_px3: rsvd1, pull-down, tristate-enable, input-disable, lp…
