TK1 PCIE Error

I have used the TK1 for one year, but now the WIFI and eth0 can not work.

Boot Message:
tegra-pcie: probing port 0, using 2 lanes
tegra-pcie: link 0 down, retrying
tegra-pcie: link 0 down, retrying
tegra-pcie: link 0 down, retrying
tegra-pcie: link 0 down, ignoring
tegra-pcie: probing port 1, using 1 lanes
tegra-pcie: link 1 down, retrying
tegra-pcie: link 1 down, retrying
tegra-pcie: link 1 down, retrying
tegra-pcie: link 1 down, ignoring

lspci: no message

ifconfig: only lo

Sometimes the TK1 has net,but it will break down and send the messagein a priod time.

While this sounds like hardware failure there is one possibility to consider first…was the Jetson accessible over the network to remote systems other than yours, and if so, was the Ubuntu user’s password still the default? Malicious removal or replacement of some parts of the system might cause the errors, and someone mistakenly trying to add x86_64 versions of armhf would be consistent with complete loss of some of those critical files.

For a few files specific to the Jetson, check if the output of this shows as ok or not:

sha1sum -c /etc/nv_tegra_release

If there is no malicious attack in the works, you might still try to flash again. If the flash fails (and you’d have to flash again even if it was a malicious attack), then you could look for the “RMA procedure” at the top of this URL:

Do note that as a general recommendation a surge suppressor is a good idea…a power spike could cause hardware failure.

Hi Kayccc,
Thank you for your response.
I have flash again.
PCIE +3.3V_LP0 and +VDD_1V5_MPCIE is ok.
