10.1 Kernel update
The NK8237 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 NK8237 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 CD.
The tool is provided as a Microsoft Installer file (MSI) and can be easily installed on
the Windows system that can connected to the NK8237 unit on the IP network.
Once installed, the NK8000Kernel_Update application can be started from the
Windows Start menu. The following window appears:
Fig. 36 Updating NK8237 Kernel
To update the NK8237 Kernel:
1. Enter the IP address of the NK8237 to update.
2. Click Update Kernel.
At that point, the tool performs a number of preliminary checks. Namely:
It verifies whether the NK8237 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 conform the update.
The Kernel update is relatively fast (about 2 min). Make sure not to power off the
NK8237 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.
