Hi, I am trying to upgrade the WP76xx Kernel to Latest R17 Release from Sierra Wireless from R16_01. Referring to this Flash size wp7607 - Legato Forum , I had a similar issue and solved rootfs file size issue by disabling UBIFS by making the following changes (See the Pic) [image] Now I am trying…

Why do you need to remove ubifs?

As I said, rootfs sizes need to be reduced. If we use ubifs the size will be more.

[MicrosoftTeams-image (6)] [MicrosoftTeams-image (5)]

mtd13 partition has size limit.

According to release note, this system partition size is fixed Do you mean you need extra space to store data?

Actually, we are adding some files to rootfs. It appears that rootfs should not be more than 30MB. If we use ubifs resulting rootfs in ubifs format will occupy more space so we cannot include our files into it.

We have already did using the patch file (details are in the sceenshot shared). Here in r16 it works fine.

does it work if you do “make” after “make clean” in order to have a clean build? how about just modifying mdm9x28-image.inc but not modifying swi-mdm9x28.conf? If i just modify mdm9x28-image.inc, the compilation is working on my side.

I tried this, it works without error for a generic image (i.e. without any of our files in rootfs). After adding our files I get the same error.

You mean you just modify mdm9x28-image.inc?

Btw, how do you add files?
