I have connected a USB modem to my BBB. In looking at the syslog, I see the
following:

I am needing to execute a script and specify which ttyUSB* but am a bit
confused on knowing which to use.

I have a device plugged in via GPIO to the following gpio pins:
48
49
115
117
If my device is connected at boot, the BB will not boot.
I am booting from eMMC. Any idea why this is occurring? I am using the
attached custom overlay which is essentially the univ-emmc overlay with

In my limited experience, I ran into a lot of issues trying to modify the
network settings as you are running into. I *believe* that the network
settings are being controlled by conman. So I added to /
etc/connman/main.conf the following:
NetworkInterfaceBlacklist=SoftAp0,usb0,usb1,{0},can0,can1
Sorry, copied and pasted from my application code that is driving the
network configuration...the {0} in NetworkInterfaceBlackist is eth0

How is UART4 enabled on beaglebone black, uname_r=4.4.113-ti-r149
Would I use
cape_enable=bone_capemgr.enable_partno=BB-UART4
in uEnv.txt?

I am running into the following error using Adafruit_BBIO.UART
UART.setup("UART4")

Where can proper "partno" values be located in order to add to this
configuration in uEnv.txt?

I ended up finding the .dts sources in /opt/source/bb.org-overlays/src/arm
where I was able to look for partno's.

I have been spending some time trying to understand device tree overlays.
Currently my uEnv.txt is configured so that:
##BeagleBone Black: HDMI (Audio/Video) disabled:
dtb=am335x-boneblack-emmc-overlay.dtb
cat /sys/devices/platform/bone_capemgr/slots
0: PF -1
1: PF -1
2: PF
ion:
bootloader:[microSD-(push-button)]:[/dev/mmcblk0]:[U-Boot
2018.09-2-gd5b4c4b656]:[location: dd MBR]
What am I missing?

Long story short, I am refactoring an application I had originally written
for Raspbian. One of the features is the ability to modify the devices
network settings (either use DHCP or set a static IP).
When refactoring this for the Begalebone, I was running into weird issues
that I assume were
] c_can_platform
481cc000.can can0: failed to open can device

Thanks for that info Robert, I will give that a shot.
Will that also affect other onboard devices like ethernet? I still want to
utilize eMMC and ethernet.

Hi,
TL;DR: What kind of signal is transmitted straight out of UART TX?
I am beating my head against a wall with a circuit I have been designing
related to UART. I know my app works as I can use a USB-to-Serial adapter
connected to beaglebone's USB0 and my app performs as expected. When I
I am running at 115200. I will try and get some decent readings with my oscope.
Thanks.

While I am likely getting in way over my head, are there any settings that
can be modified on a BeagleBone black as it relates to the UART oscillator?
I have seen some reference to the specification of the AM335x regarding:
The UART modules each have a 48MHz clock to generate their timing. They
@Paul - Would you be able to take a close up picture of the backside
solder points of the serial debug connector (3 pin next to USB C)?
