XG-XE_Switch

Switch between XGS and 10GE (XG-99S/XE99S)

The XG-99S (and OEM's) and XE-99S are hardware compatible.
By replacing the Stick firmware, it can switch between XGS-PON mode (XG-99S) and 10GE-PON mode (XE-99S).
CIG's Stick cannot switch between XGS/10GE by changing only scfg.txt

To switch between XG-99S and XE-99S, replace the following partition, file and change uboot env.

• Partition
  • dtb : mtd2 / mtd5
  • kernel : mtd3 / mtd6
  • rootfs : mtd4 / mtd7
  • mfginfo : mtd9 / mtd10
• Files
  • userdata (mtd8) partition files : /overlay (not necessary when switching XE-99S -> XG-99S)
• uboot environment
  • setpartlayout : Partition layout
  • more_args : Boot partition and options

Procedure

To prevent crashes due to exhaustion of tmpfs, the following procedure is recommended. It is strongly recommended to backup all partitions before proceeding.
Never disconnect power to the Stick while the partition is being written. Otherwise the Stick will brick.
If Stick bricked, repair according to mtd dump & Bricked Stick Repair

1. Download the firmware to be switched from Switch between XGS and 10GE and place it on the tftp server.

2. Log into the Stick root shell and go to /tmp.

3. Transfer userdata.tar.gz.

tftp -r userdata.tar.gz -g tftp-server-ip

4. Expand to /userdata. (XG-99S -> XE-99S ONLY)

tar -xvzf userdata.tar.gz -C /userdata

5. Delete the transferred userdata.tar.gz.

rm userdata.tar.gz

6. Transfer kernel.bin.

tftp -r kernel.bin -g tftp-server-ip

7. Write kernel partition.

flash_eraseall /dev/mtd3
flashcp -v kernel.bin /dev/mtd3
flash_eraseall /dev/mtd6
flashcp -v kernel.bin /dev/mtd6

8. Delete the transferred kernel.bin.

rm kernel.bin

Transfer rootfs.bin, dtb.bin and mfginfo.bin.

tftp -r rootfs.bin -g tftp-server-ip
tftp -r dtb.bin -g tftp-server-ip
tftp -r mfginfo.bin -g tftp-server-ip

7. Write dtb partition.

flash_eraseall /dev/mtd2
flashcp -v dtb.bin /dev/mtd2
flash_eraseall /dev/mtd5
flashcp -v dtb.bin /dev/mtd5

8. Write mfginfo partition.

flash_eraseall /dev/mtd9
flashcp -v mfginfo.bin /dev/mtd9
flash_eraseall /dev/mtd10
flashcp -v mfginfo.bin /dev/mtd10

9. Write rootfs partition.

flash_eraseall /dev/mtd4
flashcp -v rootfs.bin /dev/mtd4
flash_eraseall /dev/mtd7
flashcp -v rootfs.bin /dev/mtd7

10. Edit uboot environment The following error message may appear when executing this command, but this is not a problem.

11. reboot

reboot

12. Disconnect and reconnect the Stick.

13. Stick will boot with replaced firmware!

Stick's current mode can be found in the dmesg or messages log.
