Orin nano unable to start due to I2C error

I want to boot orin nano with its own carrier board.
Since the design does not have an EEPROM on board, I have changed the contents of the UBUNTU PC according to the following document

Changed contents
Linux_for_Tegra/bootloader/t186ref/BCT/tegra234-mb2-bct-misc-p3767-0000.dts

  • cvb_eeprom_read_size = <0x100>
  • cvb_eeprom_read_size = <0x0>

Reference Documents
https://docs.nvidia.com/jetson/archives/r35.4.1/DeveloperGuide/text/HR/JetsonModuleAdaptationAndBringUp/JetsonOrinNxNanoSeries.html

I then connected the UBUNTU PC to the Orin nano with a Tpe-C cable and flashed the system to the NVMe SSD.
However, the error did not change.

The error is as follows
E> I2C: slave not found in slaves.
E> I2C: Could not write 0 bytes to slave: 0x00ae with repeat start true.
E> I2C_DEV: Failed to send register address 0x00000000.
E> I2C_DEV: Could not read 256 registers of size 1 from slave 0xae at 0x00000000 via instance 0.
E> eeprom: Failed to read I2C slave device
C> Task 0x0 failed (err: 0x1f1e050d)
E> Top caller module: I2C_DEV, error module: I2C, reason: 0x0d, aux_info: 0x05
I> Busy Spin

Am I missing something?
Do I need to build the modified dts file with dtc?

What is the content of Linux_for_Tegra/bootloader/tegra234-mb2-bct-misc-p3767-0000.dts right after your flash attempt? (please be aware that I am not talking about the file you modified).

Any full log to share but not just this partial log?
What flash command are you using?

The following edits were made to both of the above files
cvb_eeprom_read_size = <0x0

Then the boot worked fine.
Thank you very much.

I guess it was because I had not edited the contents of Linux_for_Tegra/bootloader/tegra234-mb2-bct-misc-p3767-0000.dts.
