google works wonders, and unfortunately since you do not have a specific
question that's about as good as I or anyone else can do.

DHCP requires a service installed, and running at boot. A non working
serial debug cable can fail for many a reason. Is it known working ? Is it
3v3 ttl ? is it connected properly ? Which Linux image are you running on
the BBB ? Which init daemon are you running - systemd or sysv ?

As for anything, knowing a good bit about something goes a long way for
troubleshooting. You sir, will need to become intimately familiar with
Linux - Otherwise this show stops here. Also, as you can see above, there
is no one solution fix for many, or even any problem on a system running
Linux. Which is why you need to become familiar with it.

In the end, if you're running a stock image on a Beaglebone black REVC. I
can probably help you fix the DHCP issue. Set a static IP for the usb
ethernet gadget on both host, and BBB. 192.168.7.1 for host, 192.168.7.2
for the Beaglebone. netmask 255.255.255.0 will suffice. With gateway
192.168.7.1 on the Beaglebone note this as an example:

As for the serial debug cable. I can only guess at what the problem is, and
you need to answer all of the above questions first before anyone can help
you well.
