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. 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.
List firmware version
Note
There is a new firmware provided by LeoLabs that fixes issues with the stick operating at 2.5GbE speeds
- V3.3.4L3
- V3.3.4L4rc1 (Fix 2.5GbE HiSGMII)
- V3.3.4L4rc5
- V3.3.4L4 (Added failover from 2.5GbE to 1GbE, other fixes)
- V3.3.4L4V (Same as V3.3.4L4 but should be used for VEIP profiles)
- V3.3.4L5rc1 - This version adds "auto-negotiation" capability to the stick. It always prefers 1G (to keep the stick consistently accessible). When you force the link to 2.5G (disabling auto-negotiation), it takes at least 40 seconds to establish the connection.
- V3.3.4L5V (Build date: 2024-02-26 14:05:05 VEIP firmware)
- V3.3.4L6 (Build date: 2024-06-27 16:43:48)
- V3.3.4L7 (Build date: 2025-05-19 17:26:03)

Note
Firmware version V3.3.4L4rc1 or higher is required. Before editing the speed make sure your hardware supports it. If you try to use any mode not listed here, the stick will default to mode 1.
To change the link mode use this command:
# /etc/scripts/flash get LAN_SDS_MODE
LAN_SDS_MODE=0
# /etc/scripts/flash set LAN_SDS_MODE 1| Value | cat /proc/kmsg | Mode | Behavior |

This needs the OMCI_OLT_MODE value to be set 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.

The stock firmware doesn't work at 2.5GbE. There is a new firmware provided by LeoLabs that fixes this issue. Sometimes, when connecting to a Huawei OLT and cloning another ONT using GPON_SN, the Leox ONT will report O5 status but won't actually get a proper connection. Workaround - set PON_VENDOR_ID to HWTC.
