R16-WP7608-Partition-Size-Change

#1

Hi there ,
I was trying to modify the sizes of application processor partitions
using the AT command AT!PARTITION but for some reason it responds with ERROR: Not allowed . Did anyone face this issue ?

AT!ENTERCND=“A710”
OK

you can see here: (seems you cannot have partition change)

#3

Hi @jyijyi ,

Any alternate solutions ? Because the legato system build (cwe) with R16 is around 8.4MB including the custom apps .
How will i flash the system build (legato-cwe) ?

#4

You can order some new modules which can modify partition size or you need to contact local FAE to level unlock the module.

#5

@jyijyi ,
By any chance we can mute some services / libraries which were not a part of R10.1 or R13.1 Legato ?

#6

I don’t quite understand your question, can you elaborate more?

#7

@jyijyi ,
I am migrating my apps from R10.1 to R16 but unfortunately the size of legato.cwe in R16 is larger than 8 MB where as for R10.1 the size was 7.3 MB . So in order to reduce the size can i mute any default services or libraries in R16 Legato ?

#8

I never tried this, but I guess you can try to modify this file to delete some services:

#9

@jyijyi ,
Just to cross verify i muted all the services in default.sdef and the image generated was around 2.6 MB but when i tried same with R10.1 legato the image generated was 1.3 MB . Any idea what else has been added in R16 ?

We would like to achieve this because level unlocking would not be suitable for devices in the field .

#10

This is hard to compare as the code in legato framework is totally different.
But seems there is significant decrease on the size and I think you can add your app and see if it can work on the module in the field.

#11

Hi @jyijyi ,
Basically i had muted all the services just to check the image size without Legato services . I cant mute them in my use case as my applications are binding to those services .
Can we mute any other binaries or apps apart from the list in default.sdef .

Observation : In R16 with all the Legato services muted we have the cwe file size of 2.6MB and where as in R10.1 with all the Legato services muted we have the cwe file size of 1.3MB .
What is taking 1.3MB more in R16 ?

#12

How about muting wifi.sdef

#13

@jyijyi ,
I tried muting wifi.sdef the Size did not change much . Any libraries added in R16 which can be disabled ? Was 1.3 MB increment taken for bug fixing ? or any new features being added ?

#14

Legato framework has been changed a lot, you can check the release not in legato.io
