RAM_Test

介绍

毕业设计相关。 本仓库存放内存测试算法实现相关代码。

所用软硬件

raspberrypi内核编译openEuler openEuler 22.03 LTS：git clone git@gitee.com:openeuler/raspberrypi-kernel.git -b openEuler-22.03-LTS && cd raspberrypi-kernel

u-boot下使用mtest工具

编译u-boot前需在config文件中添加

CONFIG_CMD_MEMTEST=y

注意，config中CONFIG_TEXT_BASE为u-boot内存起始地址，CONFIG_SYS_LOAD_ADDR为默认加载地址

CONFIG_TEXT_BASE=0x00080000
CONFIG_SYS_LOAD_ADDR=0x1000000

使用方法为

mtest [start [end [pattern [iterations]]]]

示例

U-Boot> mtest 0x20000000 0x22000000 0xaabbccdd
Testing 20000000 ... 22000000:
Pattern FFFFFFFF55443322  Writing...  Reading...Iteration:   1094
Tested 1094 iteration(s) with 0 errors.

注意：测试地址不得覆盖u-boot所在内存
