see if this helps: [image] Repartition wp7702 IoT Modules There is an older forum topic on this. But has anyone found a way to repartition the WP7702 to increase the size of the rootfs as of 2021? The AT!PARTITION is not supposed to work on WP77xx as per the AT command re…

@jyijyi Thank you, I will look into that. Can you answer these questions: I see that original poster asked if there was a way to recover if a mistake happens. Is there away to recover? Can I adjust just one partition without adjust the others or do they need to sum up to a specific value? Thank…

I don’t know what mistakes is referring to. yes, i think so, i tried on WP76 to just adjust legato partition

@jyijyi I ran the AT!PARTITION command and got back None/Not Allowed. Is there any other way to adjust the size of the partition or some how get the application to fit. I saw this post which mentioned using the squashfs instead of ubi but they don’t say how. Thanks,

you can install the application in userapp partition by .update file Or you need to contact distributor to get the tool to enable this command

We had a lot of issues with the user partition rolling back in the WP8548 modules and then our devices weren’t recoverable remotely and had to be returned for service which is costly. Do you know if the WP7702 is improved in this area? Thanks,

rollback mechanism is a feature to protect the module among WP85/ WP77. Another way is that you put the .update file in /home/root. After that you write a script to check whether this app is installed, it not, then install it. But you need to make sure your app won’t make crash

@jyijyi The roll back was occurring after the .update image was marked good. There were devices that would go offline and when they were returned for RMA they had the original Legato image not our apps. That is why I’m hesitant to user the .update method.
