#### Setup a 5G Core
|
||||
|
||||
You will need to modify your 5G AMF config to support your PLMN and TAC. The international test PLMN is 001/01, and the international private network PLMN is 999/99. You should stick to using either of these PLMNs unless you have been issued a PLMN by your national regulator. (This PLMN will need to be configured in your gNB).
|
||||
You will need to modify the PLMN in your NRF and AMF config, and in case of AMF, further modify the TAC information. The international test PLMN is 001/01, and the international private network PLMN is 999/99. You should stick to using either of these PLMNs unless you have been issued a PLMN by your national regulator. (This PLMN will need to be configured in your gNB).
|
||||
|
||||
If you are aiming to connect an external gNB to your core, you will also need to change the NGAP bind address of the AMF **and** the GTPU bind address of the UPF. If you are running an gNB stack locally, you will not need to make these changes.
|
||||
|
||||
Modify [/etc/open5gs/nrf.yaml](https://github.com/{{ site.github_username }}/open5gs/blob/main/configs/open5gs/nrf.yaml.in) to set the Serving PLMN ID.

#### What to do if a FATAL occurs?
|
||||
|
||||
You may occasionally encounter a FATAL like the one below.
|
||||
|
||||
```
|
||||
FATAL: s1ap_build_initial_context_setup_request: Assertion `E_RABToBeSetupListCtxtSUReq->list.count' failed. (../src/mme/s1ap-build.c:577)
|
||||
01/19 22:01:49.169: [core] FATAL: backtrace() returned 10 addresses (../lib/core/ogs-abort.c:37)

||||
[1] 41823 IOT instruction (core dumped) ./src/mme/open5gs-mmed
|
||||
```
|
||||
|
||||
When a FATAL occurs, Open5GS automatically calls backtrace(), and from the address information it outputs, we can see in which source code this happened. Note the addresses 0x8ef5e, 0x5910b, 0xa4ea5, 0x88b65 in the output below. You can find those addresses in the following places.
|
||||
|
||||
```
|
||||
./src/mme/open5gs-mmed(+0x8ef5e)
|
||||
./src/mme/open5gs-mmed(+0x5910b)
|
||||
./src/mme/open5gs-mmed(+0xa4ea5)
|
||||
./src/mme/open5gs-mmed(+0x88b65)
|
||||
```
|
||||
|
||||
And you can use the GDB tool to provide additional information. If you are in a Ubuntu environment, you can install GDB as shown below.
|
||||
```
|
||||
$ sudo apt install gdb
|
||||
```
|
||||
|
||||
Then run gdb like below.
|
||||
|
||||
```
|
||||
$ gdb ./src/mme/open5gs-mmed
