Use ORIN 32G,

See README_initrd_flash

Workflow 7: Initrd Massflash
First, generate massflash package

BOARDID=3701 BOARDSKU=0004 FAB=500 BOARDREV=L.0 ./tools/kernel_flash/l4t_initrd_flash.sh --no-flash --massflash 5 --network usb0 jetson-agx-orin-devkit mmcblk0p1

Second,
Put the device in recovery mode again

Run this command:

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --showlogs --flash-only --massflash 5 --network usb0

Use R35.5.0 is OK

R3550_flash_1-11_0_20250909-164114.log (39.0 KB)

Use R36.4.3 is ERROR , show

Waiting for target to boot-up…
Timeout

R3643_202509041_beta_err.log (9.5 KB)

Are the processes for the two SDKs different? Why are the results different?

Hi,

Please retrive the serial log during flashing to debug further.

Reference URL (R36.4.3 l4t_initrd_flash.sh --no-flash 烧录问题)
use chkbdinfo

Is this still an issue to support? Any result can be shared?

9

Hi,

Please try flashing commands without BOARDREV

Just use below

BOARDID=3701
BOARDSKU=0005
FAB=501

Or put the device in recovery mode and do online massflash.

Thanks

10

The configuration in p3701.conf.common contains an error, using the outdated version 35.5.0 instead of 36.4.3, pending recompilation and testing.

12

Hi,

We noticed some typos in your commands.

Please replace mmcblkp01 with mmcblk0p1 or internal, as instructed in README_initrd_flash.txt.

Thanks

13

Use CMD

./tools/kernel_flash/l4t_initrd_flash.sh --no-flash jetson-agx-orin-devkit internal
./tools/kernel_flash/l4t_initrd_flash.sh --flash-only jetson-agx-orin-devkit internal

There is a difference between the flashing USB port of my board and the EVK.
my board flashing USB port(USB 2.0_0) directly connected to USB type C ..

Is this still an issue to support? Any result can be shared?

15

The problem still exists…dts has also been modified accordingly USB changes but the problem still exists

17

Hi,

Please share your original DTS file along with the diff for our review.
Also, try running the following command to verify if the l4t_initrd_flash tool is functioning correctly:

sudo ./tools/kernel_flash/l4t_initrd_flash.sh jetson-agx-orin-devkit mmcblk0p1

Thank you.

Hi,

The “UDC not found” error indicates that USB device mode is not activated.
What differences exist between your USB hardware and our developer kit?
Also, did you follow our adaptation guide to modify your configuration?

Thanks

主要新增這個設定 就可以直接轉為usb2.0 device

usb2-0 {

  mode = "peripheral";

  vbus-supply = <&vdd_5v0_sys>;

  status = "okay";

  usb-role-switch;

  role-switch-default-mode = "peripheral";

};

use command:

sudo ./flash.sh jetson-agx-orin-devkit internal

I think you should be using flash.sh script for flashing onboard eMMC. Use l4t_initrd_flash.sh to flash external NVMe. just check on this.

Regarding USB timeout error, might be USB cable issue some times…

I think you should be using flash.sh script for flashing onboard eMMC. Use l4t_initrd_flash.sh to flash external NVMe. just check on this.

flash.sh and l4t_initrd_flash.sh can both flash eMMC and NVMe, right?
