15.1. FLASHSTERSS example
15.1.1. 概述
FLASHSTERSS 示例工程对外部的NOR Flash进行压力测试. 主要包含如下测试内容:
使能 dcache 并且使用 API 读
erase chip (earse whole chip in once)
write 0x55
read verify
erase all block (earse one block until all block be erased)
write 0xAA
read verify
使能 dcache 并且使用内存总线读
erase chip (earse whole chip in once)
write 0x55
read verify
erase all block (earse one block until all block be erased)
write 0xAA
read verify
禁止 dcache 并且使用 API 读
erase chip (earse whole chip in once)
write 0x55
read verify
erase all block (earse one block until all block be erased)
write 0xAA
read verify
禁止 dcache 并且使用内存总线读
erase chip (earse whole chip in once)
write 0x55
read verify
erase all block (earse one block until all block be erased)
write 0xAA
read verify
15.1.2. 板级设置
无需特殊设置
15.1.3. 运行示例
当工程正确运行后，串口终端会输出如下信息：
