How to upgrade to self-compiled firmware ？

[RottenLeaf24]

I upgraded my router using the itb image from the release, but I can no longer use the bin image to upgrade. I want to compile some software myself and I end up with an image called openwrt-mediatek-mt7622-linksys_e8450-squashfs-sysupgrade.bin, how can I use it for firmware upgrade?

No, the openwrt-mediatek-mt7622-linksys_e8450-squashfs-sysupgrade.bin image is generated for the device when running the stock bootloader. You have to select the UBI variant in menuconfig, that will then result in a file called openwrt-mediatek-mt7622-linksys_e8450-ubi-squashfs-sysupgrade.itb which works with sysupgrade.

I also want to build an image of itb，But the target image only has these kinds in the picture below:

I don't know how to build an image in itb format？

As I said, you just have to select the right Target Profile:

@dangowrt Thank you very much for your help,I found It should select "Multiple Devices" in Target Profile first.

And then I can see the ubi option in the target devices.

I have compiled the firmware in itb format，It's really appreciate for solving my problem.
