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"
Extracting and repacking the rootfs
# unsquashfs mtd5.bin
# mksquashfs squashfs-root rootfs -b 131072 -comp lzma -no-recovery
Flashing a new rootfs
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
# flash_eraseall /dev/mtd7
# cat /tmp/rootfs.new > /dev/mtd7
# nv setenv sw_version1 NEW_SOFTWARE_VERSION
# nv setenv sw_commit 1
# reboot
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

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)

- 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 the 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
