Orin NX - Flashing Problems when using Custom Carrier Board and SSD (new and empty) with SOM Orin NX 16Gb

Dear,

A.Project description:

  • I am using Yocto + meta-tegra (branch scarthgap) to build the image + rootfs for my hardware
  • Hardware: SOM Orin NX + SSD (new, empty) with custom carrier board.
  • Yocto confire:
  1. local.conf
MACHINE ?= "p3768-0000-p3767-0000"

DISTRO_FEATURES = "x11 opengl "

IMAGE_CLASSES += "image_types_tegra"
IMAGE_FSTYPES = "tegraflash"

IMAGE_INSTALL:append = " l4t-launcher-extlinux "

SSTATE_DIR ?= "/home/${USER}/yocto-orin-nx/sstate_dir"
DL_DIR ?= "/home/${USER}/yocto-orin-nx/downloads"
  1. dtb after bitbake build image, there are some device tree file i have change to turn off cvb eeprom
tegra234-mb2-bct-misc-p3701-0002-p3740-0002.dts:41:            cvb_eeprom_read_size = <0>;
tegra234-mb2-bct-misc-p3767-0000.dts:13:            cvb_eeprom_read_size = <0>;
tegra234-mb2-bct-misc-p3701-0002-p3711-0000.dts:12:            cvb_eeprom_read_size = <0>;
tegra234-mb2-bct-common.dtsi:62:            cvb_eeprom_read_size = <0>;

B. My main goals

  • Boot image built by Yocto into board successfully + some of my additional layers (that is why i am using Yocto build)

C. My problems:

  • After flashing, the board enter the UEFI Interactive Shell loop (i assume it cannot find the OS image on my SSD)
  • Note that, my SSD still recognize by the Orin since it appeared on the list of Boot Manager. And for the log, please ping me for specifying the needed log, i will send later.

Please help to figured out any more step need to be done in Yocto Project, i am quite newbie so cannot find the right document to solve myself.

Thank you,

Best regards./
