8.2. Eeprom emulation 性能测试

8.2.1. 概述

EEPROM PERF示例以100笔数据,500条记录对模拟eeprom进行性能测试,主要包括以下测试内容:

初始化时间

  • format area

  • write prepared data

  • test config time

数据整理时间

  • write prepared data

  • test flush time

读取时间

  • write prepared data

  • test read time

8.2.2. 板级设置

  • 无需特殊设置

8.2.3. 说明

  • 一次写入的数据不要超过一个erase_size

  • 需在user_config.h文件中设定EEPROM_MAX_VAR_CNT限制写入数据笔数的最大数量,默认为100笔

8.2.4. 运行示例

当工程运行后,串口会打印以下信息:

check version failed, begin earse all sector, it will take some time

------------ flash->eeprom init ok -----------

start address: 0x80080000
sector count: 128
flash earse granularity: 4096
version: 0x4553
end address: 0x80100000
data write addr = 0x80080000, info write addr = 0x800fffe0, remain flash size = 0x7ffe0

valid count percent info count( 0 / 0 )
