Officially, we’ve release the source code for R13.1.3.001 for the FX30S. You can find the link on the page that you’ve reference. This version uses Legato 16.10.1.
To clarify: here’s a summary of the FX30 source code that was released:
R13.1.3.E01 - This version was released as part of the legato-spm distribution. The source code was based off an engineering version
R13.1.3.001 - Available on the Source only, not included in legato-spm.
Soon to be released:
R14 - I apologize for the delay. I realize a long time ago I mentioned a new release would be available. We are hoping to have the binary image and the Source code available within a week from now. This version will contain a Legato maintenance branch based off Legato 16.10.3. (Software will report 16.10.1.m3 but this does not mean 16.10.1)
