Re: v6.39.2 [current]

You, used the bundle package for the upgrade?
On what RouterBOARD you saw this and what RouterOS version you had before
Yes, bundle package.

It happens on CCR1009-8G-1S / RB912UAG-2HPnD / RB912UAG-5HPnD / CRS125-24G-1S. All upgrading from 6.39.1 to 6.39.2.

Re: Research on Changing Serial Number for GPON ONU Module

I see I saw it with binwalk and is huge, is it possible to repack it with canes done and flash back, any idea ? I google about hot air already I connected my module to my hawed 5608 OLT and it does not appear in iManager U2000 auto discovery, I think it has something to do with interoperability con...

Re: Research on Changing Serial Number for GPON ONU Module

How did you dump it? Dumped my sfp flash today: SPI flash structure: 1M@0(uboot), 3584K@0x100000(uImg), 3M@0x480000(rootFs), 512K@0x780000(vars), 3584K@0x800000(uImgB), 3M@0xB80000(rootFsB), 512K@0xE80000(varsB), There is a Squashfs filesystem, little endian, version 4.0, 2148429 bytes, 470 inodes,...

Re: Research on Changing Serial Number for GPON ONU Module

Based on the hardware schematic and public available information, there is large chance that the module is more like a linux computer with two bridged interfaces. This is fascinating, and a little bizarre. Surely running an entire OS on SFP is a massive overhead? After analyzing the embedded linux,...

Re: Research on Changing Serial Number for GPON ONU Module

Just analyses the rom file that you posted. There is a jffs2 at 0x7D0000, however, it is empty. it seem like there is another operating system based on linux inside the SFP module Based on the hardware schematic and public available information, there is large chance that the module is more like a ...

Research on Changing Serial Number for GPON ONU Module

The GPON ONU module is based on Marvell MC-88F6601, and the datasheet for this chip is not available for general public. I have to sign the NDA before I can get the datasheet. At beginning, I attach this module to a STM32 to dump the EEPROM which connected to SFP side. The checksun is not correct, t...

Re: cant make GPON ONU to work

Looks like changing the SN in the MAS EEPROM does not effect the SN which used to do the GPON handshake.

The chipset is Marvell MC-88F6601, but I cannot get any reference manual for that chip without signing the NDA. Looks like we have to reprogram the Marvell chip to change the GPON SN.

Looks like the server down again, and I cannot even ping the server.

No Policy Routing for IPv6

I am using HE 6in4 bgp tunnel to announce my own IPv6 space in my home for a long time without a problem. Recently, TWC adds native IPv6 support in my area. So, I get a /56 (From TWC) and a /48 (From ARIN) prefixes. I tried to use /56 for all SLAAC assignments in all vlans, and /48 for all static as...
