hello earl0054,

the --mandatory_pinmux_file is an optional switch, you may have a try to exclude that.
please also check this thread for reference, Pinmux-dts2cfg.py errors with default pinmux - #5 by JerryChang

Thanks, alot,pls have a look to the first screenshots pictures, pls check did I using the right command?

[earl0054]

remove --mandatory_pinmux_file,will make flash error

hello earl0054,

did you download pinmux spreadsheets via DLC to have customization?
may I also know which JetPack release you’re working with, thanks

[earl0054]

thanks a lot,
yes,I downloaded it’s from download center，
I use l4t 32.5.2 by ‘flash.sh jetson-xavier-nx-devkit-tx2-nx mmcblk0p1’ and it’s works well .

Hi earl0054,

We can’t reproduce your issue on TX2-NX with r32.5.2.
List our steps for you reference:

1. Download Pinmux v1.01 from Download Center.
2. Generate *.dtsi from excel file.
3. Copy *.dtsi to /Linux_for_Tegra/kernel/pinmux/t186/
4. Run below command to generate cfg file:

   $ python pinmux-dts2cfg.py --pinmux addr_info.txt gpio_addr_info.txt por_val.txt tegra186-quill-p3310-1000-a00-pinmux.dtsi tegra186-quill-p3310-1000-a00-gpio-default.dtsi 1.0 > tegra186-mb1-bct-pinmux-p3636-0001-a00.cfg
   

5. Replace tegra186-mb1-bct-pinmux-p3636-0001-a00.cfg to /Linux_for_Tegra/bootloader/t186ref/BCT/
6. Flash image:

   $ sudo ./flash.sh jetson-xavier-nx-devkit-tx2-nx mmcblk0p1
   

We are using default pinmux setting to generate dtsi.
Are you change any value from pinmux?

[earl0054]

Thanks a lot，I modified it according to the steps you provided.
this is my .dtsi file
tegra186-ws-tx2nx.dts (5.0 KB)
but can’t finish flash,Pls look at the log text. this is on 32.6.1,and also got same error on 32.5.2.

hello earl0054,

could you please also share the command-line you’re used for image flashing.

@earl0054

jetson-xavier-nx-devkit-tx2-nx

hello earl0054,

you cannot use this board name, since it’ll include TX2 NX DevKit’s board configuration file for image flashing.
please check Jetson Module Adaptation and Bring-Up chapter, you should review the steps for software bring-up process.
thanks
