This stick supports dual boot.

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

Serial

The stick has a TTL 3.3v UART console (configured as 115200 8-N-1) that can be accessed from the top surface: it's near the SFP header. TX, RX and ground pads need to be connected to a USB2TTL adapter supporting 3V3 logic.

DFP-34X-2C2 TTL Pin

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

• /tmp/omcilog - OMCI messages logs (must be enabeled, see below)

Useful binaries

• 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 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

Getting/Setting Speed LAN Mode

Note

Before editing the speed make sure your hardware supports it.

To change the link mode use this command:

# flash get LAN_SDS_MODE
LAN_SDS_MODE=0
# flash set LAN_SDS_MODE 1

Value	cat /proc/kmsg	Mode	Behavior
1	<4>change mode to 1(Fiber 1G)	FIBER	1GbaseX with auto-neg on
2	<4>change mode to 2(SGMII PHY)	TP MII	1Gb PHY
3	<4>change mode to 3(SGMII MAC)	MII	1Gb MAC
4	<4>change mode to 4(HiSGMII PHY)	TP MII	2.5Gb PHY
5	<4>change mode to 5(HiSGMII MAC)	MII	2.5Gb MAC
6	<4>change mode to 6(2500BaseX)	FIBER	2500baseX with auto-neg on
7	<4>change mode to 7(SGMII Force)	TP	1GbaseT with auto-neg off

GPON/OMCI settings

Getting/Setting ONU GPON Serial Number

# flash get GPON_SN
GPON_SN=TMBB00000000
# flash set GPON_SN TMBB0A1B2C3D

Getting/Setting ONU GPON PLOAM password

Note

The PLOAM password is stored in HEX format, without any 0x or separators

# flash get GPON_PLOAM_PASSWD
GPON_PLOAM_PASSWD=41414141414141414141
# flash set GPON_PLOAM_PASSWD 41414141414141414141

Getting/Setting OMCI software version (ME 7)

Note

This needs either OMCI_OLT_MODE to be set to 3 and firmware version 220530 or 220923 as modded by @stich86 or, if you don't want to replace the installed firmware, set OMCI_OLT_MODE value to 21. This will force the stick to use your own settings from the XML file, but this is a hack and causes sigsegv of /bin/checkomci.

# nv setenv sw_custom_version0 YOURFIRSTSWVER
# nv setenv sw_custom_version1 YOURSECONDSWVER

Getting/Setting OMCI hardware version (ME 256)

# flash get HW_HWVER
HW_HWVER=V2.0
# flash set HW_HWVER MYHWVERSION

Getting/Setting OMCI vendor ID (ME 256)

# flash get PON_VENDOR_ID  
PON_VENDOR_ID=ZTEG
# flash set PON_VENDOR_ID HWTC

Getting/Setting OMCI equipment ID (ME 257)

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

Getting/Setting OMCI OLT Mode and Fake OMCI

Configure how ONT Stick handle OMCI from OLT:

# flash get OMCI_OLT_MODE
OMCI_OLT_MODE=1
# 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...
21	Owerflow Mode	Custom Software/Hardware Version, OMCC, etc... (this is a hack and causes sigsegv of /bin/checkomci)

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

# flash get OMCI_FAKE_OK
OMCI_FAKE_OK=0
# flash set OMCI_FAKE_OK 1

Advanced settings

Setting management IP

# flash get LAN_IP_ADDR
LAN_IP_ADDR=192.168.2.1
# 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
