Using QEMU to simulate VEXPRESS-A9 (ii)---build u-boot debugging environment

Reference: http://blog.csdn.net/caspiansea/article/details/12986565

Environment Introduction

Win7 + Vmware + ubuntu12.04 32

U-boot version: u-boot-2015-04

Linux kernel version: LINUX-3.16.Y

BusyBox version: 1_24_stable

Cross-compilation Toolchain: arm-linux-gnueabi-

QEMU version: stable-2.4

download, compile u-boot code

U-boot from the following URL:

http://ftp.denx.de/pub/u-boot/

Get the code that is up to date. I am using u-boot-2015.05, unzip, configure, compile:

 Make Arch=arm cross_compile=arm-linux-gnueabi- vexpress_ca9x4_config make Arch=arm cross_compile= arm-linux-gnueabi-

Testing with QEMU

Qemu-system-arm-m vexpress-A9      -kernel u-      boot-nographic      -M 512M

Print out the boot information for u-boot:

To be continued, the following describes how to use QEMU to boot the Linux kernel with U-boot.
