Jetson Orin NX not booting on custom carrier board without EEPROM

[sudongchina]

I am trying to get Jetson Orin NX to boot on our custom carrier board. We have no EEPROM on it.

Now Jetson Orin NX can not booting up on our custom carrier board. But it can boot up on P3509 reference carrier board.

And we captured the console log from Jetson Orin NX on our custom carrier board as following:

I> Task: Prepare eeprom data (0x50017bd8)
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

Detailed boot log from Jetson Orin NX on our custom carrier board is in the attachment.

Could you please help to check that this boot failure issue is related with the custom carrier board without EEPROM or not ?

Had the same issue, quickest solution was to update the EEPROM size to 0 for the jetson-orin-nano-devkit, and keep using it in the scripts without defining a custom board:
sed -i 's/cvb_eeprom_read_size = <0x100>/cvb_eeprom_read_size = <0x0>/g' ./bootloader/t186ref/BCT/tegra234-mb2-bct-misc-p3767-0000.dts
