Hi Guys, We have a Azure IoT hub based cloud infrastructure which we use to deliver the packages/file till the devices. Devices have our own properitery agents running. I am using mender client in my yocto embedded Linux based devcies. My question is do i need the Mender server as mandatory to give…

Hello @CoderOnWinks , The Mender server is not mandatory and you can run the client in something we call “Standalone mode”, https://docs.mender.io/2.0/architecture/standalone-deployments

Thanks for the reply. I went through the documents. It says in standalone mode, we don’t have to run the mender client as a daemon. So what i will do, is write a script and watch the folder where i am expecting the update (.mender artifact) on my device. I suppose (.mender artifact) is the only thin…

[image] CoderOnWinks: I suppose (.mender artifact) is the only thing which we will push from our cloud and once it is received at devices, script will do "mender -install " where URI will be local folder path. And expected is the new (rootfs+kernel) gets flashed on secondary partition. Is this c…

[image] mirzak: That is a correct understanding. Note that you can also specific remote URI to the mender -install command. Thanks for info.

I’m not sure on whether you are performing file update (only some file or folder) or block update (rootfs). For block update (i.e rootfs+kernel), the following are the process w.r.t the standalone method: Assuming you have the .mender artifact in a file server (remote) with a specific URL. Then i…

Thanks Ajith for explanation. I am going to do block update (i.e rootfs+kernel). For that what if the .mender artifact is downloaded on my device via some mechanism through our proprietary cloud. i am planning to have a script which will do mender -install where will be my local folder path. I ho…

Hi, I am trying to use mender in standalone mode. Till now , i am able to manually patch the uboot fork which i am using. Able to build the uboot-fw-utils. Finally i am just looking for generating the .mender artifact, but in that process when i do bitbake , i get below error. The rootfs size 2097…

I believe that, you got confuse with the term steaming vs downloading. Mender do streaming where the artifact directly go to the other partition and perform the update with -install option. All the checksum and CRC will be calculated on the fly with the help of tarball and HTTPS. Hence, you can pe…

Hi Ajith, We cannot take the URL directly from our cloud. We have an agent which manages and downloads files for us from our cloud infra. Once i have that file in device, can i just use the file path in the mender -install <local_file_path> instead of a URL? Thanks, Pankaj
