Orin NX Custom Pinmux Fails To Flash

[lphillips]

I am trying to create a massflash blob for a new pinmux I created. I used v1.01 of the orin nx / orin nano series document to generate these files on the A03 page.

I have made the following changes to the pinmux in the files I use to flash Orin NX modules:

• GPIO #3, Set req initial state to drive 1
• GPIO #6, Set Pin Direction to Input, req initial state to N/A
• GPIO #12 Set Pin Direction to Output, Req initial state to Drive 1
• CAM1_PWDN Change Req initial state to Z
• GPIO #9 Change Pin Direction to bidirectional

I generate the following files with the excel sheet after making the above changes:

1. pinmux.dtsi
2. gpio.dtsi
3. padvoltage.dtsi

I then copy the padvoltage.dtsi and pinmux.dtsi files to the <l4t_top>/bootloader/t186ref/BCT/ directory and copy the gpio.dtsi file to the <l4t_top>/bootloader/ directory.

I changed the board.conf PINMUX_CONFIG and PMC_CONFIG to point to the pinmux and padvoltage files that were generate.

I use this command to generate massflash blob: sudo ./tools/kernel_flash/l4t_initrd_flash.sh --no-flash --massflash 6 -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml --no-systemimg" --network usb0 board_conf_name nvme0n1p1

I get the following error on my host PC:

[   3.2957 ] Pre-processing config: new_pinmux.dtsi
Error: Return value 1
Command cpp -nostdinc -x assembler-with-cpp -D IN_DTS_CONTEXT new_pinmux.dtsi new_pinmux_cpp.dts

Error: failed to relocate images to /home/labdesk/Desktop/Linux_for_Tegra/tools/kernel_flash/images

I tried manually running the cpp command in the <l4t_top>/bootloader/t186ref/BCT/ directory and I get the following error:

labdesk@labdesk01:~/Desktop/Linux_for_Tegra/bootloader/t186ref/BCT $ cpp -nostdinc -x assembler-with-cpp -D IN_DTS_CONTEXT new_pinmux.dtsi new_pinmux_cpp.dts

   33 | #include "pinctrl-tegra.h"
      |          ^~~~~~~~~~~

How can I resolve this error?

[lphillips]

Ah I figured it out, I had renamed the gpio.dtsi file to a different name than what was used in the excel document, I had to change that name back to the original name that the excel document assigned to the file and now I am able to generate my massflash blob.

Glad to know issue resolved, thanks for your update.
