I´m trying to install a system with a .CWE file in a WP7607 module using “fwupdate download”, apparently is doing the procedure succesfully, but it does nothing at all.
In the meanwhile, I´m doing the exact procedure with a WP8548 module and works perfectly.
The legato.cwe file has been builded for each module with their legato version
WP7607 - Legato 19.11.2
WP8548 - Legato 18.6.4
There is a chance that the cwe filesize is too big for your module.
You can capture the debug message in UART2 console port and confirm.
hello @jyijyi, my workmate tells me that he can´t capture debug messages right now.
But we have found out that our legato.cwe file for WP7607 is larger than 8 MB, is about 9MB. legato.cwe for WP85 is about 7MB
We have seen something about the size of legato partition
it is too big, legato partition size is just 8MB.

Is there anything we can do ?
reduce the size of your image by deleting some application that is not used.
Another way is you use the default legato image, but install your application by .update file instead of building the application to the image
thank you @jyijyi but I think we have already done all that
Can We resize Legato partion?
not sure if you can use the AT!PARTITION command, you can give a try:
BTW, why don’t you use .update file? .update is not using legato partition area.
because if we use updates, it will appear something else after a roll back
then probably you need to try AT!PARTITION or delete more unused application
OK, we will try AT!PARTITION or we will install a CWE with a simple app that let us recover the device remotely. Thanks!! @jyijyi
