[Fx30] Building a complete R14 customized image

IoT Gateways FX30
1

Hello,

I am using a customised Linux and Legato, built on top of the initial Fx30 R13 sources delivery.
I need to upgrade to the R14 firmware to benefit from the improvements.

I retrieved the R14 source package and imported my modifications on it.
My Yocto build environment produce several CWE files but I do not know how to rebuild a complete R14 customised image (including: boot, rmfw mcu yocto legato).

The various built packages I find in my build environment are:
~/fx30/build_bin/tmp/work/swi_mdm9x15-poky-linux-gnueabi/mdm9x15-image-minimal/1.0-r0.0/rmfw-generic.spk
~/fx30/build_bin/tmp/work/swi_mdm9x15-poky-linux-gnueabi/mdm9x15-image-minimal/1.0-r0.0/mcufw.cwe
~/fx30/build_bin/tmp/deploy/images/swi-mdm9x15/boot_wp85.cwe
~/fx30/build_bin/tmp/deploy/images/swi-mdm9x15/yocto-legato-ubifs-empty_wp85.cwe

If I combine those packages into one CWE image using the swicwe tool, I do not seems to obtain the same arrangement of parts that the default SWI Firmare R14.0.4.002 image (from https://source.sierrawireless.com/resources/airlink/software_downloads/fx30-firmware/fx30-firmware/).

Here is my custom image building command and its output:

$>  swicwe -o ~/R14-Custom.cwe -c ~/fx30/build_bin/tmp/work/swi_mdm9x15-poky-linux-gnueabi/mdm9x15-image-minimal/1.0-r0.0/rmfw-generic.spk ~/fx30/build_bin/tmp/work/swi_mdm9x15-poky-linux-gnueabi/mdm9x15-image-minimal/1.0-r0.0/mcufw.cwe ~/fx30/build_bin/tmp/deploy/images/swi-mdm9x15/boot_wp85.cwe ~/fx30/build_bin/tmp/deploy/images/swi-mdm9x15/yocto-legato-ubifs-empty_wp85.cwe

As you can see, the found parts from my custom image and on the SWI default R14 image are not identical.
The parts SYST, USER, APPS are missing from my custom image.

I’m wondering that if I do upgrade one on my Fx30 (coming initially with a FW R13 default SWI image) with my custom R14 image some parts may be missing.

Could you help me to obtain a complete R14 custom image?

Regards, Christian.

Hi Christian,
First, you’ll want to extract the Legato 16.10.1.m3 source code into your workspace: ~/fx30

Then, rename the Legato folder to just “legato” (ie, without the version)

Then you can build the system normally with “make”.

In your output folder:
~/fx30/build_bin/tmp/deploy/images/swi-mdm9x15/

Hopefully you’ll see 2 files:
boot-yocto_wp85.cwe
legato-image.wp85.cwe

In addition, the radio module image and mcufw are located here:
~/fx30/meta-columbia-x/rootfs/recipes/images/files

mcufw.cwe
rmfw-generic.cwe

You can use swicwe to concatenate these 4 cwe files together. I recommend this order:
rmfw-generic
mcufw
boot-yocto
legato

in order to make the official SWI bundle.

BR,
Chris

Hello Chris,

Thanks for your answer. I have rebuilt my image following your instructions.

Some observations:

  • the “rmfw-generic” in meta-columbia-x/rootfs/recipes/images/files is only available in SPK, not as CWE, but I guess that they are equivalent.
  • I have added at the end the “user1-single-part-ubifs-empty_wp85.cwe” to erase the USER1 partition.

Here is the image I obtain:
