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:

Note Some USB TTL adapters label TX and RX pins the other way around: try to swap them if the connection doesn’t work.

Useful files and binaries

Useful files

/var/config/lastgood.xml - Contains the user portion of the configuration
/var/config/lastgood-hs.xml - Contains the “hardware” configuration (which should not be changed)
/tmp/omcilog - OMCI messages logs (must be enabeled, see below)

Useful binaries

/etc/scripts/flash - Used to manipulate the config files in a somewhat safe manner
xmlconfig - Used for low-level manipulation of the XML config files. Called by /etc/scripts/flash
nv - Used to manipulate nvram storage, including persistent config entries via nv setenv/nv getenv
omcicli - Used to interact with the running OMCI daemon
omci_app - The OMCI daemon
diag - Used to run low-level diagnostics commands on the stick

GPON ONU status

Getting the operational status of the ONU

diag gpon get onu-state

Querying a particular OMCI ME

# omcicli mib get MIB_IDX

GPON/OMCI settings

Getting/Setting ONU GPON Serial Number

# /etc/scripts/flash get GPON_SN
GPON_SN=TMBB00000000
# /etc/scripts/flash set GPON_SN TMBB0A1B2C3D

Getting/Setting ONU GPON PLOAM password

Info The PLOAM password is stored in ASCII format

# /etc/scripts/flash get GPON_PLOAM_PASSWD
GPON_PLOAM_PASSWD=AAAAAAAAAA
# /etc/scripts/flash set GPON_PLOAM_PASSWD AAAAAAAAAA

Getting/Setting OMCI software version (ME 7)

Note This needs the /etc/scripts/flash modded

# /etc/scripts/flash get OMCI_SW_VER1
OMCI_SW_VER1=YOURFIRSTSWVER
# /etc/scripts/flash set OMCI_SW_VER1 YOURFIRSTSWVER
# /etc/scripts/flash get OMCI_SW_VER2
OMCI_SW_VER1=YOURSECONDSWVER
# /etc/scripts/flash set OMCI_SW_VER2 YOURSECONDSWVER

Getting/Setting OMCI hardware version (ME 256)

Note This needs the /etc/scripts/flash modded

# /etc/scripts/flash get HW_HWVER
HW_HWVER=V2.0
# /etc/scripts/flash set HW_HWVER MYHWVERSION

Getting/Setting OMCI vendor ID (ME 256)

Note This needs the /etc/scripts/flash modded

# /etc/scripts/flash get PON_VENDOR_ID  
PON_VENDOR_ID=ZTEG
# /etc/scripts/flash set PON_VENDOR_ID HWTC

Getting/Setting OMCI equipment ID (ME 257)

# /etc/scripts/flash get GPON_ONU_MODEL
GPON_ONU_MODEL=DFP-34X-2C2
# /etc/scripts/flash set GPON_ONU_MODEL DFP-34X-XXX

Getting/Setting OMCI OLT Mode and Fake OMCI

Configure how ONT Stick handle OMCI from OLT:

# /etc/scripts/flash get OMCI_OLT_MODE
OMCI_OLT_MODE=1
# /etc/scripts/flash set OMCI_OLT_MODE 2

Value	Note	OMCI Information
0	Default Mode	Stock setting, some values cannot be changed
1	Huawei OLT Mode	Huawei MA5671a
2	ZTE OLT Mode	ZTE
3	Customized Mode	Custom Software/Hardware Version, OMCC, etc…

Some vendors/wholesale providers/ISPs have explicit LAN Port Number provisioning or proprietary OMCI that the stick cannot understand, this will make the stick reply OK to whatever the OLT sends it via OMCI.

0 = Disable, 1 = Enable, Default is 0

# /etc/scripts/flash get OMCI_FAKE_OK
OMCI_FAKE_OK=0
# /etc/scripts/flash set OMCI_FAKE_OK 1

Advanced settings

Setting management IP

# /etc/scripts/flash get LAN_IP_ADDR
LAN_IP_ADDR=192.168.2.1
# /etc/scripts/flash set LAN_IP_ADDR 192.168.1.1

Getting/Setting the L2 Bridge MTU

Note Settings given via diag are not permanent after reboot

Getting/Setting the MTU of the L2 bridge

# diag switch get max-pkt-len port all 
Port Speed 
---------- 
0 1538 
2 2031 
# diag switch set max-pkt-len port all length 2000

Checking the currently active image

# nv getenv sw_active
sw_active=1
# nv getenv sw_version0
sw_version0=V1_7_8_210412
# nv getenv sw_version1
sw_version1=V1_7_8_210412

Booting to a different image

# nv setenv sw_commit 0|1
# reboot

Enabling the Web UI

# /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:

# ssh admin@192.168.2.1 "cat /tmp/omcilog" > omcilog.log

From the PC to the stick:

# cat lastgood.xml | ssh admin@192.168.2.1  "cat > /var/config/lastgood.xml"

Info If a Windows system is used replace type with cat and run the commands from cmd (not Powershell)

Extracting and repacking the rootfs

Warning Make sure you run both commands as root, otherwise you might get a damaged rootfs image

# unsquashfs mtd5.bin
# mksquashfs squashfs-root rootfs -b 131072 -comp lzma -no-recovery

Flashing a new rootfs

Info Only the inactive image can be flashed, change sw_versionX and sw_commit X based on the bank you have flashed

Flash 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

# flash_eraseall /dev/mtd7
# cat /tmp/rootfs.new > /dev/mtd7
# nv setenv sw_version1 NEW_SOFTWARE_VERSION
# nv setenv sw_commit 1
# reboot

Info This section is based on the V1_7_8_210412 version of the stick’s firmware

Adding support to configurable SW and HW versions, Vendor ID and equipment ID

/etc/scripts/flash can be modified in order to add support for some variables implemented in omci_app but removed from xmlconfig. The modified file is below.

flash set will still print an error but the change wil be persisted. You can check that by running the relative flash get command

Increasing the length of the software version from 13 to 14 characters

omci_app has a 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:

# 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:

-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

/etc/scripts/flash set OMCI_DBGLVL 1
/etc/scripts/flash set OMCI_DBGLOGFILE 1
reboot
/bin/omcicli set logfile 1 ffffffff

The binary log will be placed inside: /tmp/omcilog
You can convert it into a .pcap file using omcilog2pcap
You can then open it with Wireshark by installing this OMCI plugin from GitHub

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
