Error: probing the target board failed.
       Make sure the target board is connected through 
       micro-B USB port and is in recovery mode.

Was the micro-B USB cable connected to host, and was the Jetson in recovery mode? If so, was the supplied USB cable used, or was a different cable used (charging cables and many cables not used for data tend to fail)?

Before starting the flash, does this show the TX2 is found?

lsusb -d 0955:7c18'

Also, “apt remove tlp” if it is installed. It causes this issue too.

Thank you. I fixed it by removing tlp.

That also fixed it for me. Uninstall tlp, reboot, and everything works like a charm.

Hello, I have a similar problem :
I’m trying to clone a Jetson TX2 flashed with SDK Manager on to another new TX2. I have downloaded L4T 32.4.4 from Nvidia on a host PC running on Ubuntu 20.04, and I have connected the original TX2 (the one I want to clone) via USB Recovery Mode on the PC.
I tried to create a backup image from the card with
sudo ./flash.sh -r -k APP -G backup.img jetson-tx2 mmcblk0p1
but I always get the same error :
./flash.sh: line 653: Install: command not found
Error: probing the target board failed.
Make sure the target board is connected through
USB port and is in recovery mode.

Command line lsusb returns
Bus 001 Device 002: ID 0955:7c18 NVIDIA Corp. APX
and dmesg returns
[ 1.050935] usb 1-4: New USB device found, idVendor=0955, idProduct=7c18, bcdDevice= 0.00
[ 1.050939] usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 1.050941] usb 1-4: Product: APX
[ 1.050943] usb 1-4: Manufacturer: NVIDIA Corp.

I changed the USB cable with the one provided with the Jetson TX2 but it still doesn’t work. I also tried it with a different Jetson TX2 that has only been flashed with L4T and I get the same error, even though it still appears with lsusb. Uninstall tlp didn’t work either.
Does anyone know why I keep getting this ? I could really use some help here.
FIY, I’m following the steps from these websites :

Thanks !

20.04 is not supported. Technically it should be 18.04. However, SDKM can be fooled into thinking 20.04 is really 18.04. See:
