Issue flashing jetpack 4.6.2 on to jetson TX2 using SDK manager

[willpivik]

Hi guys,

I am having trouble re-flashing my Jetson TX2 using SDK manager. I am using ubuntu 18.04 as a host (no VM). I put the TX2 in recovery mode by holding down the recovery button, pressing and releasing the reset button, and releasing the recovery button after at least two seconds.

When I run SDK manager, the software recognizes the TX2 connected through USB. When the software asks how to flash the TX2, I chose the manual option. Shortly after pressing the flash button, I get an installation failure.

I have tried running the flash.sh file in the Linux_for_Tegra directory using sudo ./flash.sh jetson-tx2 nvme0n1p1. This flashes the TX2, but when the TX2 is booted, the USB port is disconnected, making it impossible to interact with.

Any advice would be really appreciated. Thank you in advanced. Bellow is the terminal output from the failed flash from the SDK manager.

Hi willpivik,

After you put device into recovery mode by manually, please use ‘lsusb’ to check you can see the device on host PC.
And using below command to flash image:

$ cd Linux_for_Tegra
$ sudo ./flash.sh jetson-tx2 mmcblk0p1

[willpivik]

Thank you for your response. I checked lsusb, and the device comes up in recovery mode as 0955:7c18 NVidia Corp. I used your line to flash, but the same issue occurs. The device boots up, but with no usb connection. Below is the picture of the boot screen showing this error.

Please check if your locale on the host is us_en or not.

[willpivik]

I am a novice with Linux, but here is my terminal output when running the locale command. Thanks again!

[WayneWWW]

Please remove your BSP folder (Linux_for_Tegra), download it again and flash the board with carolyuuu’s suggestion again.

Also, is this TX2 using developer kit? or a board from other vendor?

[willpivik]

The device I am using is this: https://connecttech.com/product/orbitty-carrier-for-nvidia-jetson-tx2-tx1/

[WayneWWW]

Since this is not devkit, please consult with the board vendor for the BSP they are using.

[willpivik]

Thanks, you are right. Sorry for the obvious mistake. Like I said, I am a novice.
