## Serial

The stick has a TTL 3.3v UART console (configured as 115200 8-N-1) that can be accessed from the top surface. To accept TX line commands, the GND of the TTL adapter should be attached to the stick's shield:

This stick supports dual boot. 

`k0` and `r0` respectively contain the kernel and firmware of the first image, `k1` and `r1` the kernel and firmware of the second one

## Enabling the Web UI
```sh
# /bin/iptables -D INPUT -p tcp --dport 80 -j DROP
```

## Transfering files from/to the stick
Works with binary files too, just run md5sum on source and destination to make sure you are not corrupting anything...
From the stick to the PC:
```sh
# ssh admin@192.168.2.1 "cat /tmp/omcilog" > omcilog.log
```
From the PC to the stick:
```sh
# cat lastgood.xml | ssh admin@192.168.2.1  "cat > /var/config/lastgood.xml"
```

{% include alert.html content="If a Windows system is used replace type with cat and run the commands from cmd (not Powershell)" alert="Info" icon="svg-info" color="blue" %}

## Extracting and repacking the rootfs
{% include alert.html content="Make sure you run both commands as root, otherwise you might get a damaged rootfs image" alert="Warning" icon="svg-warning" color="red" %}

```sh
# unsquashfs mtd5.bin
# mksquashfs squashfs-root rootfs -b 131072 -comp lzma -no-recovery
```
## Flashing a new rootfs

{% include alert.html content="Only the inactive image can be flashed, change sw_versionX and sw_commit X based on the bank you have flashed" alert="Info" icon="svg-info" color="blue" %}

So mtd4/5 if you are on image1, mtd6/7 if you are on image0.

The following commands are used to flash a new rootfs to image1 and then boot to it
```sh
# flash_eraseall /dev/mtd7
# cat /tmp/rootfs.new > /dev/mtd7
# nv setenv sw_version1 NEW_SOFTWARE_VERSION
# nv setenv sw_commit 1
# reboot
```

{% include alert.html content="This section is based on the `V1_7_8_210412` version of the stick's firmware " alert="Info" icon="svg-info" color="blue" %}

## Adding support to configurable SW and HW versions, Vendor ID and much more
`/etc/scripts/flash` can be flashed in order to add support for some variables implemented in `omci_app` but removed from `xmlconfig`. The patch is below (change the values to suit your needs)

                        exit 0
```                        
## Increasing the length of the software version from 13 to 14 characters
`omci_app` has an hard-coded limit of 13 characters for the software version, which is too low. We can binary patch it to increase it to 14 (or more, if you dare/need)
```
JVhEWjAwNCUAAAAIAAgACAAAAAAAAAAAAAAAAAAAAABvbWNpX2FwcG9tY2lfYXBwH4sIAAAAAAAA
AwMAAAAAAAAAAAAfiwgAAAAAAAADY2BoYGZgYFjh9Uq/aNcZQdXsOh3R5ktr/fd0sTEwcuTnJmfG
JxYUYJVlZGAA0gCHsMK2QQAAAAAAAEQlWERaMDA0JQ==
```
Save it as `omci_app.xdelta.base64`, then run:	
```sh
# base64 -d omci_app.xdelta.base64 > omci_app.xdelta
# xdelta patch omci_app.xdelta bin/omci_app bin/omci_app.new
# mv bin/omci_app.new bin/omci_app
```
For reference, the patch changes the follwing section of the omci_app:
```diff
-00408c24 24 05 00 0e     li         a1,0xe
+00408c24 24 05 00 0f     li         a1,0xf
-00408cf0 24 05 00 0f     li         a1,0xe
+00408cf0 24 05 00 0f     li         a1,0xf
```
(It's inside the function referencing the string `OMCI_SW_VER1`)

The original file md5sum is: `4aea2f72bacc11256b7e2c1583d2ad4f`
The patched file md5sum is: `da20327c4c002e4c27f82f6ee63dbc1a`

## Enabling PLOAM logging

```sh
/etc/scripts/flash set OMCI_DBGLVL 1
/etc/scripts/flash set OMCI_DBGLOGFILE 1
reboot
/bin/omcicli set logfile 1 ffffffff
```
1. The binary log will be placed inside: `/tmp/omcilog`
2. You can convert it into a .pcap file using [omcilog2pcap](https://github.com/hack-gpon/omcilog2pcap)
3. You can then open it with Wireshark by installing the OMCI plugin from [GitHub](https://github.com/hack-gpon/omci-wireshark-dissector)
   
If you want to log everything since the stick boots, you can create a custom rootfs. Place the last command inside `etc/runomci.sh` as the last line of the file
