Hi everyone, I used to work on Legato V16.04 using the following setup: Firmware Version: SWI9X15Y\_07.08.02.00 r31088 CARMD-EV-FRMWR1 2016/02/05 23:29:29 Bootloader Version: SWI9X15Y\_07.08.02.00 r31088 CARMD-EV-FRMWR1 2016/02/05 23:29:29 Linux Version: 3.14.29ltsi-5d7a6bf7c6\_ed88cc68b5 #20 PREEMPT Mon Oct 10 14:07:33 UTC 2016 I have developed a Legato app for a WP85xx that reads the GPS data using the fix on demand API as illustrated in the function Testle\_pos\_getInfo() on the following example: > **[Sample code for Fix On Demand - Legato Docs](http://docs.legato.io/latest/c_posSampleCodeFixOnDemand.html)** > > legato™ is an open source Linux-based embedded platform designed to simplify connected IoT application development Everything worked fine until I upgraded to Legato v16.07. My current setup is the following: Firmware Version: SWI9X15Y\_07.11.11.00 r33161 CARMD-EV-FRMWR1 2016/09/20 16:36:44 Bootloader Version: SWI9X15Y\_07.11.11.00 r33161 CARMD-EV-FRMWR1 2016/09/20 16:36:44 Linux Version: 3.14.29ltsi-c14b887744\_0c284d02b3 #6 PREEMPT Mon Oct 24 11:01:10 UTC 2016 In order to compile successfully my APP I had to upgrade the Legato developer studio to V4.1.1.201609120935 and use as a target platform: [Built-in] Legato for WP85/WP75 (16.7.0.wp85-wp75-native-x86\_64-201610241259) - WP85XX When I run my GPS APP i get the following output in my legato framework log: ``` Nov 7 12:27:03 | Legato | supervisor[23774]/supervisor T=main | resourceLimits.c SetRLimitValue() 282 | Setting resource limit maxQueuedSignals to value 100.

Thank you in advance 🙂 Best regards, Nick ---

Hi Nick, did you try a clean build? Maybe the incremental build is not detecting the framework has changed, and didn’t rebuild all that needs to be rebuilt… ---

Hi Daav, Thanks for your answer. Yes I did a clean build to the GPS\_APP. The helloWorld2 app is a new project so I built it after I installed the new framework. ---

Hi Nick, just done the test here, and after a clean build, the app is running fine on Legato 16.07 Please can you make sure of the Legato version running on your device?
