Hi All, I am using WP7702 which came wih mangOH red, I updated the VM with the latest tool chain as described by dfrey in the topic > [@Error starting redSensorToCloud \[Solved\]](https://mangoh.discourse.group/t/error-starting-redsensortocloud-solved/1849): > > I’m working with a brand new mangOH Red with WP7702 and using the Getting Started Guide. Everything goes smoothly until I get to starting app redSensorToCloud. Here is the message and log output: root@swi-mdm9x28-wp:~# app start redSensorToCloud There was an error. Application 'redSensorToCloud' could not be started.

@hposhtiw I noticed the **[wp77xx]** section of your **cfglegato** output is a bit different from mine, specifically the **y22-ext-** is not present in your toolchain path – mine is below. ``` [wp77xx] Toolchain dir = /opt/swi/y22-ext-wp77xx/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi prefix = arm-poky-linux-gnueabi- sysroot = /opt/swi/y22-ext-SWI9X06Y_02.18.05.00/sysroots/armv7a-neon-poky-linux-gnueabi kernelroot = /opt/swi/y22-ext-SWI9X06Y_02.18.05.00/sysroots/armv7a-neon-poky-linux-gnueabi/usr/src/kernel ``` In @dfrey post [here](https://mangoh.discourse.group/t/error-starting-redsensortocloud-solved/1849/7?u=drew), #4 instructs to use a destination path including **y22-ext-** and #5 is setting up a symlink to that destination path (yours differs here). I don’t know how important (if at all) setting up the paths exactly like this are, but maybe it’s something worth considering. What is your output for the following? ``` mangoh@mangoh-vm:~$ ls /opt/swi/y22-ext-wp77xx -lha lrwxrwxrwx 1 root root 28 Sep 6 20:03 /opt/swi/y22-ext-wp77xx -> y22-ext-SWI9X06Y_02.18.05.00 mangoh@mangoh-vm:~$ ``` Good luck.
