Hi, it was suggested I post this questions here (from the Sierra Wireless forum). [Link to SW forum post](https://forum.sierrawireless.com/t/how-to-update-legato-framework-on-fx30s/9667/7)

What is the correct toolchain/AF to build for use with FX30s FW 16.10.1.m3 (R14) from here [https://source.sierrawireless.com/resources/airlink/software\_downloads/fx30-firmware/fx30-firmware/](https://source.sierrawireless.com/resources/airlink/software_downloads/fx30-firmware/fx30-firmware/)

16.10.1.m3 FW has been released for the FX30. I presume 16.10.3 is the toolchain /AF I should use to build for this version? The reason I ask is because I have updated my FX30s to 16.10.1.m3 and built my application using the 16.10.3 toolchain, but I am getting the

error, which else where on the forums is suggested is a version mismatch between the FW and toolchain / AF? However I can’t find reference to the correct toolchain for 16.10.1.m3 on the Source.

I also get the FW version mismatch error when installing the application using Developer Studio 5.3.

Any help is appreciated,

Thanks,

Karl

The R14 toolchain is available here:

[https://source.sierrawireless.com/resources/legato/download/linuxtoolchain9x15-32bit](https://source.sierrawireless.com/resources/legato/download/linuxtoolchain9x15-32bit) (32 bit)  
[https://source.sierrawireless.com/resources/legato/download/linuxtoolchain64bit9x15](https://source.sierrawireless.com/resources/legato/download/linuxtoolchain64bit9x15) (64bit)

Please ensure that your application is also rebuilt with legato 16.10.1.m3 and the toolchain before deploying it.

Thanks @esun (and @cchenry) for this. Is there a version of this I can install to be available in Developer Studio?

@daav,  
A new FX30 release R14.0.4.002 is available (on the Source in tarball format) and Enoch posted the toolchain. Is there an easy way Karl can add this to DevStudio?  
Thanks,  
Chris

Hi All,

If anyone is looking for the **legato** source bundle, it’s now available on [the source here](https://source.sierrawireless.com/resources/airlink/software_downloads/fx30-firmware/fx30-firmware/).

mostly worked for me.

ciao, Dave
