TX2 Cannot Connect to Internet

I have replaced with the original Image.But it still cannot work.

Please re-flash the device for this. We should check if hardware is dead.

ok,thanks.

FYI, if you check “uname -r”, this is how modules are searched for. Changing the Image implies possibly changing kernel module search location if CONFIG_LOCALVERSION was not correct. Using either image see what you get for “uname -r”. See if in both cases this directory exists and is populated:

/lib/modules/$(uname -r)/

Losing part of the kernel can result in some of the effects you are seeing.

Hi WayneWWW,

I am trying to reflash my bord,but it always failed,flash_os_tx2.log shows as following:

It looks weird that the process has error when rootfs copies to device.

Few questions:

  1. Does rootfs folder still exist under your Linux_for_Tegra folder?
  2. Does jetpack ask your host password when flash? There is some permission denied error.

Do you still have the temporary file from the “Linux_for_Tegra/bootloader/” subdirectory, “system.img.raw”? From that directory is there still spare space via “df -H -T .” (and is it type ext4)? What is the exact byte size of that file:

ls -l system.img.raw

Does the following work?

sudo -s
mount -o loop,ro system.img.raw /mnt
ls /mnt
umount /mnt
exit

Are you on a public network where you share a router with other people? If so, have you changed passwords?

Hi chay1991,

Have you clarified the cause and resolved it?
Any result can be shared?

Thanks

Hi Kayccc,
I refrash my board then it can work normally.It may be caused by change the Image file.
