How to use the Jetson Nano's Pinmux spreadsheet?

Autonomous Machines Jetson & Embedded Systems Jetson Nano
#1

Hello.
I found new Jetson Nano’s update files.

-> Jetson Nano Developer Kit Users Pinmux Configuration Table New 1.0 2019/06/10

I tried to export DTS files, but I could not. I got a few “*.dtsi” files by this spreadsheet.

I could not get “.dts" files or ".dtb” files…

Anyone please tell me how to get the “dtb” files ???

Where I should copy this file to ?

I want to get functions(I2S, SPI, PWM and so on).

Maybe I guess… If I can get the “dts” files, I try to execute the command.
->dtc -I dts -O dtb -o xxxxxxxxxx.dtb xxxxxxxxxx.dts
->sudo ./flash.sh -r -k DTB jetson-nano-qspi-sd mmcblk0p1

This is my Nano’s pic :-)

JETSON NANO B01 I2C0 config as GPIO

hello devemin,

please refer to previous release documentation TX2 Configuring Pinmux GPIO and PAD for the steps to generate cfg file from pinmux spreadsheet.
thanks

Hello JerryChang.

Thanks a lot for your comment!

So I try the link, but I can’t find “pinmux-dts2cfg.py” in path “Linux_for_Tegra / kernel / pinmux /”. (L4T R32.1.0)

Did I have to download R28 ? Is the old version worked for R32?

And I don’t understand that why I use “cfg” file for alternation of “dts” .

Should I use “cfg” file ? Not “dts”?
( I guess that this way need to build kernel, “dtb” way didn’t need to build it.)

Thank you.

hello devemin,

nice catch, it seems we’ll need python scripts for Nano platforms.
we’ll investigate this internally, stay tuned.
thanks

#5

Thank you for investivation and your busy time !

I’ll wait for it.

I like the Jetson’s platform :-)

#6

hello devemin,

sorry, Nano platforms don’t need python scripts for conversions.
you have to update the kernel sources to modify the device tree settings,
for example, modify below to customize GPIO settings.
$TOP/kernel_src/hardware/nvidia/platform/t210b01/porg/kernel-dts/porg-platforms/tegra210b01-porg-p3448-a01-gpio-default.dtsi

#7

hello JerryChang.

Thanks for Reply.

I tried it.
But I got Errors. (Some fix goes to success compilation. but I don’t know is it correct…)

Can you give me some advices ?

  1. Downloaded files from https://developer.nvidia.com/embedded/dlc/l4t-sources-32-1-jetson-nano

  2. I used the spreadsheet, And I exported 2 *.dtsi files.
    (with Jetson_Nano_DeveloperKit_Users_Pinmux_Configuration.xlsm)

  3. I copied the files with overwriting to
    $TOP/public_sources/hardware/nvidia/platform/t210/porg/kernel-dts/porg-platforms
    -> tegra210-porg-gpio-p3448-0000-a02.dtsi
    -> tegra210-porg-pinmux-p3448-0000-a02.dtsi

  4. cd $TOP/public_sources/kernel/kernel-4.9
    zcat /proc/config.gz > .config
    make O=build/jetson-nano/ oldconfig
    make O=build/jetson-nano/ dtbs

    (“make Image” got same result.)

  5. I got this errors about “suspend_gpio”.
    (so I try Next 5’s modification.)

  1. I modified and add “tegra210-porg-gpio-p3448-0000-a02.dtsi”, with “suspend_gpio”, I copy the code from default file.

    so I compiled successfully. but …

     suspend_gpio: system-suspend-gpio {
 		status = "okay";
 		gpio-hog;
 		output-low;
 		gpio-suspend;
 		gpios = <
 			TEGRA_GPIO(A, 6) 0
 			>;
 };

  2. I got the “dtb” files at $TOP/public_sources/kernel/kernel-4.9/build/jetson-nano/arch/arm64/boot/dts

    I have not written yet this file to Nano’s SD card.

I want to tell me that is this means correct ?

And Why did I get this errors about “suspend_gpio” with using official spreadsheet ?

I would appreciate your reply.
I apologize for the inconvenience, but thank you for your consideration.

I continued to try this. But the kernel did not boot up.

I copied the all of “*.dtb” files and kernel Image to SD card at path “/boot/”.

and then configured the “/boot/extlinux/extlinux.conf”

I was able to write the dtb files, and Nano boot.

I copied *.dtb file to Linux_for_Tegra/kernel/dtb/tegra210-p3448-0000-p3449-0000-a02.dtb

sudo ./flash.sh --no-systemimg -k DTB jetson-nano-qspi-sd mmcblk0p1

boot, No edited extlinux.conf

sudo cat /sys/kernel/debug/tegra_gpio
then SPI’s CNF has changed.

I don’t know yet this…

I want to tell me that is modifition with adding “suspend_gpio” means correct ? (#7 comments)

And Why did I get the errors about “suspend_gpio” with using official spreadsheet when building dtb files ?

Anyone can tell me this ?

#10

hello devemin,

there’s known issue that pinmux spreadsheet is not align with public release sources. please expect next public release (l4t-r32.2) will fix this failure.

also, summarize the steps for using the Jetson Nano’s Pinmux spreadsheet.

  1. Download the pinmux spreadsheet from Jetson Download Center
  2. Generate the dtsi file from pinmux spreadsheet. (you’ll generate 2 dtsi files)
  3. Copy these dtsi files to the ubuntu host
  4. Download the kernel sources from Jetson Download Center
  5. un-tar the sources package
  6. overwriting dtsi files for building.

Hello JerryChang.

Grateful thanks for this.

I’ll expect L4T-r32.2.

I wish you the best.

Until R32.2, I will use this dtb instead of spreadsheet.

SPI :
https://devtalk.nvidia.com/default/topic/1050427/jetson-nano/enabling-spidev-on-the-jetson-nano-is-hanging-when-flashing/post/5338398/#5338398

I2S :
https://devtalk.nvidia.com/default/topic/1051776/jetson-nano/enabling-i2s-audio-output-on-40-pin-connector/

PWM :
No data.
Maybe we can use GPIO pin No.32(PM3_PWM0), No.33(PM3_PWM2).

Thanks.

Hi Jerry,

I noticed that “Jetson Nano Developer Kit 40-Pin Expansion Header Configuration” PDF was released yeaterday. Unfortunately, following the steps you get stuck at the error:

ERROR (phandle_references): Reference to non-existent node or label "suspend_gpio"

You mentioned that the error would be fixed with the release l4t-r32.2. When could we expect the release to take place? Is there any way to fix the problem before the release?

Thanks,

Kira

#13

hello kira_canada,

please update the device tree manually, you should copy the code from the default file.
for example,

suspend_gpio: system-suspend-gpio {
 			status = "okay";
 			gpio-hog;
 			output-high;
 			gpio-suspend;
 			suspend-output-low;
 			gpios = <
 				TEGRA_GPIO(A, 6) 0
 				>;
 		};

we’re currently close to l4t-r32.2 release,
stay tuned.

#14

Hi Jerry,

Thank you for information. I will stay tuned.

Best,

Kira

#15

That’s quite the nano set up you have there. I don’t know if you’re connected to these guys (or if it might be you), but there’s a Japanese robotics shop that seems to be getting through many of these configurations as well.

I’ve come across their GitHub page before, thank you for the pointer. Their scripts helped me get an I2S microphone to work on my Jetson.

Hello
i flashed dtb file successfully by following ‘Jetson Nano Developer Kit 40-Pin Expansion Header Configuration’ file

what could i do next!!!

@ washiu hello, I think I may have the same problem as you. I asked support on the following link:

https://devtalk.nvidia.com/default/topic/1057627/jetson-nano/jetpack-4-2-1-spi/post/5367885/#5367885

Unfortunately, I do not have yet the serial cable for debug, so I could not go further to investigate. I should receive it soon, but in the meantime, I kind of have to rely on external support to diagnose.

I’ll have a look in more details to your log. Please let me know if you find anything on your side.

for info, what modification did you do to the pinmux spreadsheet: enable SPI? other outputs?

#19

hello wahsiu,

could you please also share what’s the modification you had done.
thanks

Ok, I now have a serial cable. I have something similar on the log.

Log when it doesn’t boot:

Err:   serial
Net:   No ethernet found.
Card did not respond to voltage select!
** Bad device mmc 1 **
Hit any key to stop autoboot:  0

Log when it does boot (no modification of pinmux):
