【经验】RL78系列MCU高速CRC校验,仿真运行结果不一样,该如何解决?
现在的产品,应用都要求满足功能安全,还有国际标准对应,为了对应IEC60730以及IEC61508安全标准,瑞萨电子RL78系列MCU产品内置了安全功能,其目的是通过单片机的自诊断,在检测到故障时能安全的停止工作。
安全功能中,安全功能标准要求确认闪存内的数据是否完整,并建议CRC校验作为比较常用的手段,RL78所提供的高速CRC可以在初始化程序中进行整个代码闪存的检查,检查时间短,效率高,迅速的判断系统内存数据是否正常,给系统作出预警。
我们建立工程,以RL78/G13/R5F100LE为例,实现高速CRC校验,根据寄存器设定,将代码闪存区域(00000H~0FFFFBH)作为对象来进行运算,并在编译器中与Object Converter的运算结果进行比较,若比较一致,我们使用GPIO控制LED进行闪烁指示。
首先,程序中设置高速CRC运算范围及控制方式,如下图:
图一:寄存器设置对应图
图二:寄存器设置示例
其次,编译器CS+ for CA中Object Converter选项设置,如下图:
图三:CS+编译选项设置
最后应用程序中进行对比,如下图:
图四:计算结果与编译器输出结果比较
完成了程序设计以及编译器配置,开始调试,发现无法编译成功,系统报错为:
图五:编译报错
这个原因为,调试监控区与CRC结果存储区冲突,于是更改调试监控地址或区间大小,如下:
图六:更改仿真调试监控区间
然后进行调试仿真,发现两个结果不同,如下图:
图七:Object Converter生成CRC结果
图八:高速CRC结果寄存器
分析一下,结合一开始编译不通过情况,因为CRC校验是对整个FLASH闪存区进行数据校验比对,而调试预留的区间也在校验范围之内,Object Converter 得到的高速 CRC 运算结果配置在 0FFFCH~0FFFDH 上,而这个区域是片上调试预约区域,所以会产生竞争。同时,而在仿真调试过程中,监控区的数据是不断变化的,所以会出现不同的 CRC 运算结果,而导致比对失败。
所以,在执行高速CRC校验时,需要在Link Option 中设置禁止片上调试动作,程序编译完成后,通过下载软件将HEX文件下载至MCU中,脱机运行,即可保证所计算的CRC结果与Object Converter所产生的结果一致。
最后,关闭仿真调试选项,如下图:
图九:关闭调试功能
使用编程软件将编译生成的HEX/MOT文件下载至MCU中,脱机运行,CRC结果比对一致,LED指示闪烁。
结论,在执行高速CRC校验过程中,不能打开调试功能,配置编译完成后,需要将程序下载至MCU脱机运行,否则,无法达成CRC匹配。

【经验】MCU进入休眠模式后,静态电流不满足低功耗指标的问题解析
工程师在设计产品时,实现功能很简单,但要集成系统应用保持稳定工作并保证低功耗指标,就不是一件很容易的事情了,明明MCU的电气参数电流指标为微安级别,但设计完系统进入休眠模式后,静态电流却是毫安级别,甚至于大几十毫安,高出了标准的几十上百倍。本文以Renesas瑞萨电子RL78或RH850为例,介绍分析静态电流不满足低功耗指标的步骤,找出可能导致静态电流高的原因。
