When burning multiple boards simultaneously, errors is reported

Autonomous Machines Jetson & Embedded Systems Jetson AGX Orin
1

with JP5.1.2 ，sdk 35.4.1，AGX orin 32GB， i flash taget ,with “tools/kernel_flash/README_initrd_flash.txt”, the “Workflow 7” .
I did the following：
step 1 : I made image with “sudo BOARDID=3701 FAB=TS4 BOARDSKU=0004 BOARDREV=A.0 ./tools/kernel_flash/l4t_initrd_flash.sh --no-flash --massflash 5 --network usb0 jetson-agx-orin-devkit mmcblk0p1”
step 2: Put all of connected Jetsons into RCM mode.
step 3:cd mfi_jetson-agx-orin-devkit
step 4:“sudo ./tools/kernel_flash/l4t_initrd_flash.sh --showlogs --flash-only --massflash 5 --network usb0”

but with error,

Hi,

what host OS version do you use? Please use Ubuntu 18.04 in case it’s 20.04/22.04.
Try with different USB cable/ports, and flash the device one-by-one to see which one will trigger the timeout error.
You may also do this on the host PC:

sudo -s
echo -1 > /sys/module/usbcore/parameters/autosuspend

Hi @DaveYYY ：
My host is 20.04,and when i flash only one device,log is attached.
flash_3-10_0_20230808-163856.log (7.2 KB)

What’s the flash command you used this time?
Can you reboot your host PC and try again?

6

If the USB timeout error keeps happening, please try with 18.04 and also this command:

Hi:
On the Xavier nx board, the 18.04 system is used.
on nx system to flash the orin.

Hi：
Can i use docker image 18.04?

9

You cannot use a Jetson device to flash another Jetson device.
Please use a x86 host PC instead.

Hi:
I installed ubuntu18.04 on a virtual machine, but the problem still exists.
i run command “sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --massflash 5 --network usb0”

Please do not use virtual machines. They are unstable and not verified by us.
Use a real Ubuntu 18.04 host PC.

Hi:
我使用了虚拟机，然后在我 执行了解压 Tegra_Linux_Sample-Root-Filesystem_R35.4.1_aarch64.tbz2，到 mfi_jetson-agx-orin-devkit/rootfs 下之后，在烧写，就可以正常烧写多个模块了。
我不太明白，为什么还和mfi_jetson-agx-orin-devkit/rootfs 这个目录有关系，和mfi_jetson-agx-orin-devkit/rootfs/mnt这个目录也有关系。而烧写进板子里的文件系统，并不是mfi_jetson-agx-orin-devkit/rootfs里的内容。
Hi:
I used a virtual machine and then performed decompression Tegra_ Linux_ Sample Root Filesystem_ R35.4.1_ Aarch64.tbz2, to mfi_ After running Jetson Agx Orin devkit/rootfs, multiple modules can be burned and written normally.
I don’t quite understand why you’re still with mfi_ The directory jetson agx orin devkit/rootfs is related to mfi_ The directory Jetson agx orin devkit/rootfs/mnt is also relevant. And the file system burned into the board is not mfi_ The content in Jetson agx orin devkit/rootfs.

所以你現在的問題是什麼？
燒進板子裡的是什麼東西？

可能只是一開始你的檔案沒有解壓縮完全，有缺少東西所以失敗而已。

14

還有其實你可以說中文就好，你下面那一段的英文不知道是不是用翻譯的，看起來很不通順…

15

烧进板子里的，是我真正制作的rootfs，因为这时我已经用我真正的rootfs制作出来了system.img，而不是我解压的Tegra_Linux_Sample-Root-Filesystem_R35.4.1_aarch64.tbz2这个基础文件。 很有可能是因为rootfs不全，但是，我不明白已经有了system.img，为什么还要有rootfs这个目录呢，这样会导致，制作出来的mfi_jetson-agx-orin-devkit.tar.gz会很大。

16

MFI的package本來就會把system.img和rootfs目錄一起包進去
但是實際壓縮之後應該是不會佔到兩倍的容量的
