Kernel update

The NK823x Kernel is the main component of the operating system, which acts as a
bridge between the application and the hardware level.
In certain conditions, it may be necessary to update the Kernel, following specific
instructions of the technical support. In such cases, you can use the
NK8000Kernel_Update Setup.msi tool that is available in the NK8000 - Support Tools
folder of the DMS8000 DVD.
The tool is provided as a Microsoft Installer file (MSI) and can be easily installed on the
Windows system that can connected to the NK823x unit on the IP network.
Once installed, the NK8000Kernel_Update application can be started from the
Windows Start menu. The following window appears:
Updating the Kernel
To update the Kernel:
1. Enter the IP address of the NK823x to update.
2. Click Update Kernel.
At that point, the tool performs a number of preliminary checks. Namely:
It verifies whether the NK823x firmware is compatible with the new Kernel. If not, a

message will instruct you to download a new firmware and try updating the Kernel
again.
It verifies whether the existing Kernel is older, the same, or newer then the new

Kernel and prompts you to confirm the update.
It verifies whether there is enough free memory space to install the new Kernel. If

not, the NK823x configuration will be temporarily removed to free memory space.
You will be prompted to choose whether to restore the configuration at the end of
the Kernel upgrade or not (the latter can be useful to save time if you are
upgrading the system and are going to download a new configuration from
Composer).
The Kernel update may take several minutes. Make sure not to power off the NK823x
unit or the Windows computer during the updating procedure.
If needed, you can show the Kernel version by clicking the About button. Note that two
Kernel versions are presented that are automatically selected for the NKM8001-A1 or
the NKM8001-A2 mainboard, respectively.
