upstream

LxNETES is based on various open source projects. The original source code from these projects is stored in this folder. The following source code is included:

Linux

Buildroot

U-Boot

This folder contains the source code of U-Boot including all patches which are necessary for the specific target.

Memory layouts

Flash memory layout

The partitioning of the nonvolatile memory is described in this following table.

ConnectCore 9P 9360 / ConnectCore 9P 9750

Flash Start Address	Size	Partition Name	mtdblock/

0x00000000	0x00040000	U-Boot	0

0x00040000	0x002C0000	Kernel	1

0x00300000	(Size of flash – 3MB)	rootfs	2
