We just flashed our VOXL2 with SDK 1.3

There is no ```px4``` folder in the ```/data``` directory. I have tried running ``` voxl-configure-px4-params -w``` and selected both the defaults and FPV_RevB_V4 and nothing gets populated in the ```data/px4``` location.

Should we roll back to SDK 1.2? Or are the px4 params stored somewhere else now? The px4 start script still looks in  ```/data/px4/param/parameters```

@restore It sounds like something went wrong with your SDK install, what process did you follow for installation? Did you download the SDK from our downloads page, untar it, and run `./install.sh`?

@tom yes - that is how I installed it

@restore If your reboot your VOXL 2 do the parameters then show up in `data/px4/param/parameters` ? That path has not changed

@tom no - I have rebooted a few times and it is still not there. No px4 directory in /data

@tom  a full wipe SDK install sorted it out. Thanks

@restore How did you do full wipe? Can you please post the steps to do so?

@riteshsharma do the SDK installation with ```./install.sh -w``` option. This will wipe the entire file system including the ```/data``` partition which is usually untouched.
