Figure 9-3 Displayed log

Possible Cause 2

SSH connection authentication timed out.

By default, GSSAPIAuthentication is enabled for SSH. GSSAPIAuthentication based on Kerberos takes a long time.

Possible Cause 3

Failed to execute the card making script due to timeout.

The performance of the SD card for the Atlas 200 AI accelerator module deteriorates if the SD card has been used for a long time. As a result, formatting the SD card times out (longer than 30 minutes) and fails. Figure 9-5 shows the card making log.

Possible Cause 4

The eMMC does not have a partition table.

Redundant information may be generated when you obtain the drive letter name from the card making script . As a result, the card fails to be made. View the card making log. See Figure 9-6.

Solution

For Possible Cause 1, run the ping 192.168.0.2 command to check the network connection. If the network connection has been returned to normal, re-make the card.

For Possible Cause 2, modify the /etc/ssh/ssh_config file, set GSSAPIAuthentication to no, and then re-make the card.

For Possible Cause 3, replace the SD card with a new one and then re-make the card.

For Possible Cause 4, modify the formatSDcard function in the make_ubuntu_recover.sh script as shown in the following figure and then re-make the card.
