A common question from both new & existing customers is which version of NoTouch OS should I install onto my device. As NoTouch OS is a multi-hardware architecture & multi-kernel OS, hopefully, the explanation below might help with this. It also means that NoTouch OS can run on hundreds of different devices regardless of hardware architecture.
So, let’s break this down and look at some of the different builds that can be downloaded from the customer portal.
Here is an example of one of the latest versions of NoTouch OS builds.
lnx-3.3.203-EEs-k512-x64-210829.lfi lnx-3.3.203-EEs-k510-armhf-210829.lfi lnx-3.3.203-EEs-k413-x64-210829.lfi lnx-3.3.203-EEs-k404-x64-210829.lfi
[lnx-3.3.203] denotes the build version, and the final part so the [3.3.x] will increase over time as we create new builds.
[EEs] denotes that this is our standard image, and if you have access to special or custom images then this could change to something like EEa for Amazon Workspaces, EEf for Nutanix Frame and so on.
[k512] is the kernel version that is being used. This is the important bit, and wherever possible we would suggest that you use the latest kernel version, particularly for newer x64 hardware.
[x64] or [armhf] is referring to the hardware architecture, with [armhf] referring to (arm hard float) and is for devices like the Raspberry Pi.
 is the date the build was created.
[.lfi] this is the file format that the firmware is delivered in.
Kernels 2.6 [k206] and 3.5 [k305] for 32-bit devices are still supported but newer features might not make it into these OS images anymore as our technology partners reduce support for this hardware type.
When it comes to updating devices, we make this simple for our customers regardless of the age or hardware architecture of devices in groups. As such you can have a mixture of x86, x64 & armhf devices in a group.
Upload ALL the required firmware images into NoTouch Center under ‘Resources/VDI Client Images’
Next, browse to the group of devices you wish to update and select the image version you’d like to update. Note that NoTouch Center will then work out which image needed to be installed based on [Image Class], [Image kernel] & [Image Architecture]
As a rule of thumb, we recommend that you always try the latest kernel which at the time of writing in September 2021 is k512 for x64 and k510 for armhf devices like the Raspberry Pi. It goes without saying that you should test on a device to ensure it works and meets your requirements, and if it does then you can roll this out to other devices on the network using NoTouch Center. If however, you are unsure, then please contact Stratodesk Support for further advice or join our Slack Community to ask community members.
