I am trying to get Orin to boot on our custom board. We have no EEPROM on it. In the Jetson bring-up guide it says that I need to change the read_size from the default 0x100 to 0x0 (- cvb_eeprom_read_size = <0x100>

  • cvb_eeprom_read_size = <0x0>). I made that change in Linux_for_Tegra/bootloader/tegra234-mb2-bct-common.dtsi. Then I flash Orin with the flash.sh script “sudo ./flash.sh jetson-agx-orin-devkit mmcblk0p1”.
    The result is the same (failed).

Hi,

0xa0 is the address cvm eeprom. Not cvb eeprom. If cvm eeprom is not able ot get read, then it seems to be hardware problem.

Yes, it’s hardware problem of our carrier board.
