Also I keep getting these errors when I try to debug, any ideas

The documentation for syscfg settings is in the packages themselves.
Both of the above settings are defined by the
@apache-mynewt-nimble/nimble/transport package. You can see the full list of
settings in a project, along with their descriptions, with this
command:
newt target config show <target-name>
However, I don't think you will see either of these settings if you execute
this command. From the dependency list you quoted, it looks like you are using
an older version of Mynewt which does not support these two settings. I
believe you are using Mynewt 1.3.0; you will want to upgrade to 1.4.0, released
about one week ago. There was a long delay between the releases of 1.3.0 and
1.4.0, and I mistakenly forgot that 1.4.0 was not yet released when I wrote my
original email.
The latest version introduces some fairly major changes, so I suggest you
upgrade as follows:
1. Download Newt 1.4.0 as described here:
http://mynewt.apache.org/develop/get_started/native_install/index.html
2. Upgrade the Mynewt repos to 1.4.0 by running:
newt upgrade
inside your project directory.
> 2. How can I make sure it's configuring the right UART?
There is a syscfg setting defined by
@apache-mynewt-nimble/nimble/transport/uart called `BLE_HCI_UART_PORT`.
By default, this is defined to be 0. You can change its value if you need to
use a different UART.
> 3. Do I change the target syscfg or the one in the app folder?
I recommend changing the target's syscfg. The target configuration overrides
the app configuration, and it is best not to change a foreign repo except when
necessary. The syscfg system is described in more detail here:
http://mynewt.apache.org/develop/os/modules/sysinitconfig/sysinitconfig.html

The boot loader is not strictly required, but much of the Mynewt infrastructure
assumes it is present. When you are getting Mynewt up and running for the
first time, I recommend you use the boot loader so that you can follow the
documentation more closely.
