Platform : AGX Orin
Jetpack : 5.0.2
board : custom carrier board
I use the commands in tools/kernel_flash/README_initrd_flash.txt to flash, but it always show timeout
Here’re flash log’s and uart logs during flashing process
flash_1-3_0_20230213-175224.log (7.5 KB)
initrd_flash_uartlog_fail.txt (36.4 KB)
Ths same process on devkit is okay
flash_1-1_0_20230213-163016.log (123.8 KB)
initrd_flash_uartlog_devkit.txt (88.9 KB)
I’ve tried to modified the EEPORM settings in Linux_for_Tegra/bootloader/tegra234-mb2-bct-common.dtsi
(refernce Making massflash blob on AGX Orin - #3 by KevinFFF)
Our carrier board has a EEPORM, but it does nothing
Does EEPORM need to modify any values for booting?
Have you referred to the
adaptation guide for your custom board?
From your uart log of the custom board, it could not enter kernel, there’s might something missing in device tree.

I can use flash.sh for flashing and can boot up successfully
And all function is correct on our carrier board
I’m not sure why initrd can’t flash
Is that related to my dts?
Here’s flash command:
sudo ./flash.sh jetson-agx-orin-devkit mmcblk0p1
I think that would be fine if you could flash and boot up success with flash.sh on your custom carrier board.
Do you modify any configuration for the custom board?
(You use the board config for the Orin devkit)
Have you tried the following command from
Workflow 1 of README_initrd_flash.txt on you custom board?
$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh jetson-agx-orin-devkit mmcblk0p1
Please provide the flash log and serial console log for further check?
February 14, 2023, 6:07am
Yes, I have tried the Workflow1 and It also stopped at “Step 3: Start the flashing process”
The log showed timeout
uart_log_failed.txt (37.4 KB)
initrd_flash_log_failed.txt (199.6 KB)
Uart log showed
“RAS Uncorrectable Error in IOB, base=0xe010000:”
What is IOB error?
Are you connecting your carrier board with 4K Monitor?
Please try to disconnect the monitor while boot up.
I’ve found some similar threads with this error.
Please refer to the following threads and check if it could help.
Newly flashed AGX Orin black screen on reboot - Jetson & Embedded Systems / Jetson AGX Orin - NVIDIA Developer Forums
Jetson AGX Orin will not start when the monitor is power on - Jetson & Embedded Systems / Jetson AGX Orin - NVIDIA Developer Forums
Or update to Jetpack 5.1 with new UEFI release.

I didn’t connect 4K monitor
I just connect power and Micro USB for flashing and an uart log debugger
I’ll try to build new UEFI to test
Does your custom board change any UPHY configuration?
February 14, 2023, 7:25am
Yes, I’ve changed UPHY configuration#2
Did you change the ODMDATA?
February 14, 2023, 7:29am
Yes here’re what I changed
Did you disable unused interface in the device tree? For example, if MGBE is not in use anymore, please disable it in DT.
February 14, 2023, 7:39am
Yes, all unused interface are disabled including MGBE
Should we offer our modified dts files?
Just a clarification. You can use flash.sh to flash + boot up your custom board but initrd cannot do it, is this the situation right now?
Are you using same board config in initrd flash and flash.sh? Did you also enable PCIe controller C7?
The address 0x3f600c0 from your log indicates this is related to P2U_GBE_4 which is related to PCIe C7
February 14, 2023, 8:05am
Yes, the board config is the same
Yes, PCIe controller C7 is enabled

I’m trying to build UEFI, and I reference this
building without docker
After I execute build.sh, the log showed error
ERROR - Could not find appropriate folder for mu_nasm. Host(os=‘Linux’, arch=‘ARM’, bit=‘64’)
ERROR - Could not find appropriate folder for edk2-acpica-iasl. Host(os=‘Linux’, arch=‘ARM’, bit=‘64’)

uefi.txt (188.3 KB)
it seems something lost, is there any directly tar file for download instead of downloading by git?
Are you using standalone X86-64 Ubuntu 18.04 or 20.04 as your host PC?
Do you follow all the steps from
Build without docker to setup build environment?
February 15, 2023, 8:52am
Yes My host is X86-64 Ubuntu 18.04
But I build UEFI on my ARM Ubuntu target
Should I build on host?
All my steps are following the Github
