Hi Jason,
You are right after a long time of wait I can log into the BBB again. I use the
‘dmesg’ and 'journalctl', I found the following:

After I manually set up the IP interface under IPv4 of my computer. It still
take a long time to log in the beaglebone. Also,
After I command “/sbin/route add default gw 192.168.7.1”
I was unable to ping 8.8.8.8, it will automatically stop there is no packets
exchange.

Hi Jason,
I was trying to reconnect my BBB via usb this morning. Everything works fine
yesterday. I can log into the BBB via Putty but today, I can’t login via SSH. I
did ping 192.168.7.2 it does not work. I also see two LEDs flashing when I plug
the BBB and after a little while the LED 3 turns off. I think there’s some eMMc
configure issue going on.
The most common failure mode for the network connection once drivers are
installed properly is a lack of the board providing a DHCP lease. This
represents an issue with the flash imaged that wasn't caught on some versions.
The work-around is to either wait a long time for the DHCP lease to work or
manually assign your computer the IP address 192.168.7.1 (mask 255.255.255.252,
no gateway) on that interface.
USR3 should stop blinking once the system boot becomes stable. USR3 is the eMMC
access indicator by default. USR0 should continue to blink in a heartbeat
fashion. The default LED modes are shown on
https://beagleboard.org/getting-started.
You can confirm the issue by using a serial adapter to capture the kernel log.
Alternatively, there is a virtual serial adapter that should be functioning
fine if your drivers were installed properly. Log in and store the output of
'dmesg' and 'journalctl' to see if the issue can be shown.
I wonder if I can get any suggestion from you.
Work with serial access for the time-being and provide a log so that we can
suggest a better long-term fix to avoid the issue, which I suspect is related
to not providing your host with a DHCP lease.
Please be sure to provide the image version stored in ID.txt or /etc/dogtag.
Best regards,
Jiye
