This stick supports dual boot.
k0 and r0 contains respectively the kernel and firmware of the first image, k1 and r1 of the second one
## List of firmware and files
## Useful files
- `/var/config/lastgood.xml` - Contains the user portion of the configuration
- `/var/config/lastgood-hs.xml` - Contains the "hardware" configuration (i.e. that _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 samewhat safe manner
- `xmlconfig` - Used to low-level manipulate the XML config files. Called by `flash`
- `nv` - Used to manipulate the 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
## Useful commands
### Enable the Web UI
```sh
# /bin/iptables -D INPUT -p tcp --dport 80 -j DROP
```
### Check the currently active image
```sh
# nv getenv sw_active
sw_activ=1
# nv getenv sw_version0
sw_version0=V1_7_8_210412
# nv getenv sw_version1
sw_version1=V1_7_8_210412
```
### Boot to a different image
```sh
# nv setenv sw_commit 0|1
# reboot
```
### Get/Set the ONT S/N
```sh
# /etc/scripts/bin flash get GPON_SN
GPON_SN=TMBB00000000
# /etc/scripts/bin flash set GPON_SN TMBB0A1B2C3D
```
### Get/Set the ONT PLOAM password
Note: the password is in ASCII format
```sh
# /etc/scripts/bin flash get GPON_PLOAM_PASSWD
GPON_PLOAM_PASSWD=AAAAAAAAAA
# /etc/scripts/bin flash set GPON_PLOAM_PASSWD AAAAAAAAAA
```
### Query a particular OMCI ME
```sh
# omcicli mib get MIB_IDX
```
## Low level modding
Note: this section is based on version `V1_7_8_210412` of the stick
### Trasnfer 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:
```sh
# ssh admin@192.168.2.1 "cat /tmp/omcilog" > omcilog.log
```
From the PC to the stick
```sh
# cat lastgood.xml | ssh admin@192.168.2.1 "cat > /var/config/lastgood.xml"
```
**Note:** on windows replace type with cat and run the commands from cmd (not powershell)
### Extract and repack the rootfs
```sh
# unsquashfs mtd5.bin
# mksquashfs squashfs-root rootfs -b 131072 -comp lzma -no-recovery
```
### Flash a new rootfs
**Note: you can only flash the inactive image**. So mtd4/5 if you are on image1, mtd6/7 if you are on image0.
The follwing examples flashes a new rootfs to image1 and boots to it
```sh
# flash_eraseall /dev/mtd7
# cat /tmp/rootfs.new > /dev/mtd7
# nv setenv sw_commit=1
# reboot
```
### Add support to configurable SW and HW versions, VENDOR ID and much more
We can patch `/etc/scripts/flash` in order to add support for some variables implemented in `omci_app` but removed from `xmlconfig`. The patch is below (change the values to suit your needs)

```
### Increase 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)
```

Save it as omci_app.xdelta.b64, then run:
```sh
# 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:
```diff
-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 referecing the string `OMCI_SW_VER1`)
