Transplantation of DM8168 dvr rdk nand System
Nand boot preparation:
Method 1: Set the Startup Mode of DM8168 to SD card boot. After U-boot is started, run U-boot to write the applicable bootloader of nandflash to DM8168.
Method 2: This is also the method I have selected. It is simple and crude. Use the CCS project to write uboot_NAND_DM816X_TI_EVM to nandflash on the premise that there is a simulator.
I mentioned before the method of writing: http://
1. Background
No DVR scenarios are used:
It is clear from the diagram that the east-west and north-south traffic will be centralized to the network nodes, which will make the network nodes a bottleneck.
If you enable DVR, the following figure:
For east-west traffic, traffic is passed directly between compute nodes.
For the north-South flow, if there is floating IP, traffic directly to the compute
