Ubiquiti ER-X: create custom image

For Developers
1

Hi,
I've got an Ubiquiti ER-X flashing with Openwrt. I have made many changes and created modules.

Now, how to create a flashable image of openwrt (at the current state)?

This is the layout:

root@Openwrt:/# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00080000 00020000 "u-boot"
mtd1: 00060000 00020000 "u-boot-env"
mtd2: 00060000 00020000 "factory"
mtd3: 00300000 00020000 "kernel1"
mtd4: 00300000 00020000 "kernel2"
mtd5: 0f7c0000 00020000 "ubi"

I have try to boot (in RAM) mtd2, mtd3, mtd4, mtd5.
mtd4 actually boot with my customization (I tried it on the device itself).
mtd5 is big! 240MB

Any ideas?
Thanks

Sorry, my English is horrible :sweat_smile:

That's not what I meant to say.
I want to create a backup firmware (included all my modules, packages and configurations)
so that I will be able to flash another device and it will be ready.
