Your idea with USB devices give me some hopes !
Here are the results of my last tests :
TEST 1 : with my laptop with UBUNTU on a external USB disk (/dev/sdb) :
lsblk -f
NAME FSTYPE LABEL MOUNTPOINT
sda
├─sda1
├─sda2
└─sda3
sdb
├─sdb1 /
├─sdb2
├─sdb5 [SWAP]
└─sdb6 /home
sr0
No FSTYPE but i format “/” and “/home” as ext4
lsusb -t
/: Bus 05.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M
/: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M
/: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/8p, 480M
|__ Port 1: Dev 2, If 0, Class=Mass Storage, Driver=usb-storage, 480M
|__ Port 3: Dev 10, If 0, Class=Vendor Specific Class, Driver=, 480M
|__ Port 4: Dev 3, If 0, Class=Imaging, Driver=, 480M
Devices (USB drive and Jetson in recovery mode) always go on the same root_hub. Maybe because my laptop have only one USB2 controller
Unsurprisingly : “Error: Return value 4”
TEST 2 : I found 51GiB on my internal hard drive (/dev/sda) to install UBUNTU
lsblk -f
NAME FSTYPE LABEL MOUNTPOINT
sda
├─sda1
├─sda2
├─sda3
├─sda4
├─sda5 /home
├─sda6 [SWAP]
└─sda7 /
sr0
I have some free space
df -H -k

I have only Jetson in recovery mode connected to USB :
lsusb -t (after flashing)
/: Bus 05.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M
/: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M

|__ Port 3: Dev 8, If 0, Class=Vendor Specific Class, Driver=, 480M
|__ Port 4: Dev 2, If 0, Class=Imaging, Driver=, 480M
Unfortunately “Error: Return value 4”. All my hopes are gone. Do you have any other idea ?
