memtester内存测试工具移植到imx6ul开发板中测试
主机平台： UBUNTU14.04硬件平台：明远智睿MY-IMX6UL-EK140
内核版本 ：linux-4.1.15
交叉编译链：arm-linux-gnueabihf(gcc version 5.3.1)
1.下载源码：
http://pyropus.ca/software/memtester/
2.创建编译目录：
$ mkdir /home/myzr/my-work/source_tar/memtester
把下载的源码放入此目录中
3.解压进入源码目录：
$ tar xvf memtester-4.3.0.tar.gz
$ cd memtester-4.3.0/
4.配置交叉编译环境变量：
$ source ~/my-work/03_toolchain/gcc-linaro-5.3/environment-setup-gcc-linaro-5.3-arm.sh
5.配置memtester编译选项：
$ vi conf-cc
把cc改为：arm-linux-gnueabihf-gcc
arm-linux-gnueabihf-gcc -O2 -DPOSIX -D_POSIX_C_SOURCE=200809L -D_FILE_OFFSET_BITS=64 -DTEST_NARROW_WRITES -c
This will be used to compile .c files.
$ vi conf-ld
把cc改为：arm-linux-gnueabihf-gcc
arm-linux-gnueabihf-gcc -s
This will be used to link .o files into an executable.
6.编译
$ make
7.测试：
把编译出的可执行文件memtester复制到开发板中
给文件添加一个可执行权限：
# chmod +x memtester
进行测试：
# ./memtester 10M 2
memtester version 4.3.0 (32-bit)
