CN913x Build - Script

Introduction

The main intention of this manual is to provide build scripts that are easy to handle compared to Marvell's build environment and self build for CN913x based products.

git clone https://github.com/SolidRun/cn913x_build.git

The runme.sh script is meant to build a ready to use image containing:

mv-ddr-marvell - from mainline
GitHub - MarvellEmbeddedProcessors/mv-ddr-marvell
arm-trusted-firmware - from mainline
GitHub - ARM-software/arm-trusted-firmware: Read-only mirror of Trusted Firmware-A
** mrvl_scp_bl2.img is not public yet. it is provided in the binaries folder
u-boot - from Marvell SDK
patches are applied on git://git.denx.de/u-boot.git
linux - from mainline
GitHub - torvalds/linux: Linux kernel source tree

U-Boot based on SDK10

The CN913x u-boot is not public yet, and was taken from Marvell's SDK10

In order to use use the script with the SDK 1186 patches, create a directory in ROOTDIR:

mkdir $ROOTDIR/patches-sdk-u-boot/

Extract the git-u-boot--.tar.bz2 under the destination folder git-u-boot-- and copy the patches

cp <sdk patch directory>/Base_SDK/base-patches-SDK-10.3.3.0-PR8/uboot/git-uboot-2019.10-SDK-10.3.3.0-PR8/*.patch patches-sdk-u-boot/ $ROOTDIR/patches-sdk-u-boot/

The script will apply the u-boot patches onto the mainline u-boot.

If the SDK patches directory doesn't exist, the script will take by default the u-boot.bin provided in the binaries directory.

Run Script

The script will generate a ready to use images at ROOTDIR/images. flash_image.bin for SPI and cn9132_cex7_config_0_ubuntu.img for eMMC or SD card

Deploy

For SD card bootable images:
Plug in a micro SD into your machine and run the following, where sdX is the location of the SD card got probed into your machine -

In u-boot prompt, to continue booting from SD card:

For burning only the flash-image.bin on an SD card
