Dear mangOH team, I’m experimenting quite a lot of troubleshooting these past days. Still I can’t push any data from my mangOH (WP8548) to the AV platform and I could understand now why possibly. I had to downgrade the embedded FW to R14 instead of R15. The Legato release associated to my VM (following the getting started) is the 17.07.2. After investigating on the forum, it seems that 17.10 or even 17.11 shall be the one to be used. But the question is: is there an .ova file for the 17.11 or do we have to build it for the WP8548? Thanks in advance to anyone offering help here. Rudy ---

Hi Rudy, We will release an .ova in the next two weeks with latest legato release. thanks & regards, Ashish ---

Hi Rudy, If you are using release 14, and want to update to latest Legato then you can do the following: a. cd legato\_framework/ b. repo status c. repo sync d. repo init -m legato/releases/18.01.0.xml e. repo sync Note you can always update to the latest version of legato on the VM, you just need to point to the latest release in step d. cheers, Ashish ---

Hi Rudy, I have discussed this point with Sierra last Friday. I would wait for the new ova release based on 7.11 and in the meantime keep working on the 16.10.4. If you upgrade the legato framework to 7.05 or later dev studio will keep on complaining that the target is not in line (still 16.10.4). Gilles ---

@Gilles Steps listed above work to upgrade VM to 17.11 or 18.01. It is no different than getting a new VM ---

Ashish, Yes this is correct, it is possible to update the legato platform thorugh those steps. I’ve tried it a couple of weeks ago. It works fine. The problem is that there is no WP8578 FW with legato 17.11 inside and therefore platform and target are not aligned. This results in warning from dev studio and crashed of the target once downloading apps to the target. A package brings latest platform/target/apps in line with each other and should work fine, Gilles ---

We would definitely require a new .ova package based on 17.11 or above, OR, an Windows .exe file with embedded FW R14 for WP8548 and Legato 17.11. Thansk much! Rudy ---

Can you an app status? Seems like your unit is trying to connect to WiFi service? did you configure the unit for WiFi? Is the unit registered to AV? ---

I didn’t configure the unit for WiFi. For now, I don’t want to even use WiFi. These are default configs.

Hello Gilles Just to add your custom legato build to dev studio. Example : if you build legato 17.11 you can add this to a new package in dev studio. I think you a tuto in this forum to how add a custom legato build to dev studio. ---

It works fine. > > The problem is that there is no WP8578 FW with legato 17.11 inside and therefore platform and target are not aligned.

If you follow the getting started guide, and update Legato in VM as described, do you still have a problem? Note, we dont support Dev Studio from mangOH Team perspective. However if you are interested in using Dev Studio, you can update as shown in instructions here > **[Adding newest version Legato Framework into Developer Studio](https://forum.legato.io/t/adding-newest-version-legato-framework-into-developer-studio/2654/5)** > > You’re welcome, guys, I’m glad this is helpful. By the way we’re working on some improvements in DS 5.3 to build the framework from DS itself. Target for release is October – stay tuned 😉 ---

Hello Ashish, I’m using the VM terminal for all what is described in the getting started. I’m using the Dev Studio for the logs only for now. Much easier to use. I have still the same issue even after updating the legator version like you described (up to 18.01). Still some api/ apps bindings issues. redSensorToCloud is crashing after a few seconds. Like Gilles said, there seems to be misalignment still between the target and the platform. We’d need a new package for WP85. From what I hear around, all this is resolved when using the WP76. I don’t have any WP76 unfortunately to perform the same tests. Rudy Thanks for the support.
