How to Enable GPIO7 and GPIO14 as PWM8 and PWM7 on Xavier-Nx module

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 included using the pinmux configuration spreadsheet to generate a device tree, but that did not work this time. It seems like the spreadsheet doesn’t control the pinmux in Xavier-Nx. Any suggestions on what to do?

Hi sgamu,

Unlike Jetson Nano, Xavier NX is using cfg file (tegra19x-mb1-pinmux-p3668-a01.cfg) to control the pinmux instead of dtb.

Did you use the correct method to generate the cfg file?

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-a01.cfg. Given that the cfg file is in the bootloader directory, do I need to build u-boot with ‘make 3450-porg_defconfig’ and ‘make’ OR would a simple re-flash after the cfg file modification work?

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 more questions, but you should check out how the spreadsheet works.

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/pinmux/t19x$ ls
addr_info.txt       mandatory_pinmux.txt  pinmux-dts2cfg.py  README.txt
gpio_addr_info.txt  pad_info.txt          por_val.txt

Seems pwm can work on another customer’s case.

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 GPIO14 in the cfg file is:
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, lpdr-disable. So I changed GPIO7 to
pinmux.0x0243d030 = 0x00000410; # gp_pwm3_px3: gp, tristate-enable, input-disable, lpdr-disable

After building and flashing the module, I used the instructions below to try to trigger a PWM signal on the module:

cd /sys/devices
Displayed 4 pwm devices 3280000.pwm, 32c0000.pwm, 32d0000.pwm and 32f0000.pwm
32d0000.pwm always produced a ‘resource busy’ message when ‘echo 0 > export’ was done. So I assumed that was being used by GPIO14 whose amplitude could be changed using this command echo X > /sys/devices/pwm-fan/target_pwm.

To figure out if GPIO7 was mapped to any of the 3 pwm devices (3280000.pwm, 32c0000.pwm, 32f0000.pwm), I tried these commands on all 3 and probed the pin for a PWM signal without success.

CONFIG_PWM_SYSFS=y
cd 32X0000.pwm/pwm/pwmchipY
echo 0 > export
cd pwm0
echo 200000 > period
echo 100000 > duty_cycle
echo 1 > enable

Any more pointers/clues would be greatly appreciated.

Here’s the dmesg:

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, lpdr-disable. So I changed GPIO7 to
pinmux.0x0243d030 = 0x00000410; # gp_pwm3_px3: gp, tristate-enable, input-disable, lpdr-disable


Also GPIO 7 is PWM 8 and GPIO14 is PWM5
I am not sure how you are seeing GPIO14 is working.
The correct pinmux registers are:
gpio7:
pinmux.0x02430040 = 0x00000056; # soc_gpio44_pr0: rsvd2, pull-down, tristate-enable, input-enable, io_high_voltage-disable, lpdr-disable
gpio14:
pinmux.0x02434090 = 0x00000414; # soc_gpio12_ph0: rsvd0, pull-down, tristate-enable, input-disable, lpdr-disable

Can you please change value to 0x455 in both the registers and check PWM signals?

Thanks,
Shubhi

I made the changes you recommended but nothing changed. GPIO 14 still shows as a PWM signal on the oscilloscope, but GPIO7 stays at 0. The changes were made in this cfg file: tegra19x-mb1-pinmux-p3668-a01.cfg. The file exists in 2 places, so both were modified. See the changes below:

pinmux.0x02430040 = 0x00000455; # NVIDIA says GPIO7 = PWM8
pinmux.0x02434090 = 0x00000455; # NVIDIA says GPIO14 = PWM5

On the pinmux spreadsheet, GPIO07 is the same as GP_PWM8, but GPIO14 is GP_PW6.

I believe this is what GPIO7 should be:
pinmux.0x02430040 = 0x00000401; # soc_gpio44_pr0: gp, tristate-disable, input-disable, lpdr-disable

because GPIO14 is actually this:
pinmux.0x02434098 = 0x00000401; # soc_gpio13_ph1: gp, tristate-disable, input-disable, lpdr-disable

I was wondering if I can get more insight/input from NVIDIA as the suggestions above don’t work. Comparing the pinmux configuration spreadsheet to the pinmux.cfg file, I am certain that the register for GPIO14/PWM6 is 0x02434098 while the register for GPIO7/PWM8 is 0x02430040.

Like I said earlier, GPIO14/PWM6 works by default without any alterations, but GPIO7/PWM8 stays low when it is assigned the same value as GPIO14/PWM6 e.g. 0x455, 0x401, 0x409, 0x405, GPIO7/PWM8 never works. The value change to GPIO14/PWM6 however only seems to affect the starting duty_cycle/ cur_pwm value i.e. is it 130 or 0.

Since all the nodes pertaining to PWM are blank (i.e. it says status= “okay”) on the device tree, I was wondering if there would need to be a device tree change for a particular node from those shown below? Else could someone please give me other suggestions about geting GPIO7/PWM8 to work?

pwm@3280000 {
status = “okay”;
};

pwm@32c0000 {
status = “okay”;
};

pwm@32d0000 {
status = “okay”;
};

pwm@32f0000 {
status = “okay”;
};
pwm@c340000 {

Hi sgamu,
As I mentioned above, correct registers are:
gpio7:(Pin 32 on 40-pin header)
pinmux.0x02430040 = 0x00000056; # soc_gpio44_pr0: rsvd2, pull-down, tristate-enable, input-enable, io_high_voltage-disable, lpdr-disable
gpio14: (FAN pin present on SOC)
pinmux.0x02434090 = 0x00000414; # soc_gpio12_ph0: rsvd0, pull-down, tristate-enable, input-disable, lpdr-disable

The register pinmux.0x02434098 = 0x00000401; # soc_gpio13_ph1 is CPU_OVR_VID pin which is also going to GPIO14.
The fan PWM pin is unsed in default case and we use CPU_OVR pin which is already configured as PWM. That’s why you are seeing it as working.

Can you just dump following registers in working case of GPIO14?
0x02434098 (GPIO14: PWM6: CPU_OVR_VID)
0x02434090 (GPIO14: PWM5)
0x02430040 (GPIO7)

Also, try writing value 0x401 to register 0x02430040 and check pwm on Pin 32 of 40-pin header.
Let me know the results.

Thanks,
Shubhi

These are the values below after changing 0x02430040 to 0x401. Also pin32 on the 40-pin header is 0 on the oscilloscope.
busybox devmem 0x02430040
0x00000401
busybox devmem 0x02434090
0x00000414
busybox devmem 0x02434098
0x00000401

Hi sgamu,
Can you tell me about your setup how are you checking pwm signal on 40-pin?

Hello Shubhi,

I don’t have a devkit for Xavier-Nx. I have a generic devkit that I use from time to time for flashing the Xavier-Nx module and running quick tests which has a 40 pin header. So I performed the test you requested on that devkit by probing pin 32 of the 40 pin header.

Before this devkit detour, I have been using a custom designed board for testing GPIO14 (FAN) and GPIO7. GPIO14 is either PWM signal by default once the device is ON or able to be triggered as such using this command “/usr/bin/jetson_clocks” if the signal is low. The duty_cycle is controlled from here /sys/devices/pwm-fan/target_pwm or /sys/devices/pwm-fan/cur_pwm and it is attached to this device node: /sys/devices/32d0000.pwm

For GPIO7, after using the commands below to trigger it, it stays at 0. BTW, I’m using Release 32.4.1.

cd /sys/devices/32*0000.pwm where * is any of these hex numbers (8, c, f)
OR
cd /sys/devices/c340000.pwm

echo 0 > export
cd pwm0
echo 2000 > period
echo 1000 > duty_cycle
echo 1 > enable

Hi sgamu,
Can you please give this experiment results to check if pin is actually toggling when it is GPIO:

  1. Do not use pin as PWM, keep it gpio
  2. short Pin 31 and 32 on 40-pin header
  3. echo 424 > /sys/class/gpio/export
  4. echo 416 > /sys/class/gpio/export
  5. echo out > /sys/class/gpio/gpio416/direction
  6. echo in > /sys/class/gpio/gpio424/direction
  7. echo 1 > /sys/class/gpio/gpio416/value
  8. cat /sys/class/gpio/gpio424/value
    ##measure voltage at pin 32, it should be 3.3V
  9. echo 0 > /sys/class/gpio/gpio416/value
  10. cat /sys/class/gpio/gpio424/value
    ##check voltage at pin 32, it should be 0V
    Repeat from step 7 for 3-4 times.
    Let me know the results.
