## EEPROM (I2C slave simulated EEPROM)
The Huawei MA5671A does not have a physical EEPROM, the Falcon SOC emulates an EEPROM by exposing it on the I2C interface as required by the SFF-8472 specification.
On the I2C interface there will be two memories of 256 bytes each at the addresses `1010000X (A0h)` and `1010001X (A2h)`, however in reality the memory available from the emulated EEPROM will be 640 bytes each but only the first 256 bytes will be exposed in the I2C interface.
The Huawei MA5671A stores the content of the emulated EEPROM in U-Boot env variables to restore it after a reboot:
- `EEPROM0 (A0h)` stored in U-Boot env variable `sfp_a0_low_128`
- `EEPROM1 (A2h)` stored in U-Boot env variable `sfp_a2_info`

# Useful commands
## Transferring files to the stick
{% include alert.html content="If you use a modern OpenSSH version (e.g. >= 8.8) you will have to use the legacy protocol and enable some deprecated algorithms: scp -O -oKexAlgorithms=+diffie-hellman-group1-sha1 -oHostKeyAlgorithms=+ssh-dss [...]" alert="Info" icon="svg-info" color="blue" %}
```sh
# scp rootfs.bin root@192.168.1.10:/tmp/
```
## Backup of all partition
Make a backup of all partitions, an easy way is:
- On the stick run:
```shell
cat /proc/mtd
```
- For each mtdX run, on computer shell:
```shell
nc -l -p 1234 > mtdX.bin
```
And in the lantiq shell:
```shell
cat /dev/mtdX | nc 192.168.1.11 1234
```
## Flashing a new rootfs
{% include alert.html content="Only the inactive image can be flashed" alert="Info" icon="svg-info" color="blue" %}
The following commands are used to flash a new rootfs to image1 and then boot to it
```sh
# mtd -e image1 write /tmp/rootfs.bin image1
# fw_setenv committed_image 1
# fw_setenv image1_is_valid 1
# reboot
```
{% include alert.html content="Some OLTs don't like when ONTs don't boot from image 0, therefore the previous procedure must be preceded by the following procedure with inverted images, as to clone image 1 into image 0" alert="Warning" icon="svg-warning" color="yellow" %}
## Cloning of mtd1 (image 0) into mtd5 (image 1)
{% include alert.html content="Image 0 can be flashed to image 1, while image 1 cannot be flashed to image 0 because it has larger rootfs_data" alert="Warning" icon="svg-warning" color="yellow" %}
The following commands are used to clone image0 to image1 and then boot to it
```sh
# cat /dev/mtd2 > /tmp/mtd2.bin
# mtd -e image1 write /tmp/mtd2.bin image1
# fw_setenv committed_image 1
# fw_setenv image1_is_valid 1
# reboot
```
