AUTOSAR NvM
AUTOSAR NvM是一种用于非易失性存储器(NVM)管理的标准。根据引用\[1\],NVM Block可以分为三种类型:NATIVE、DATASET和REDUNDANT。AUTOSAR NvM模块的配置是基于AUTOSAR标准,不受限于任何工具。在使用AUTOSAR NvM时,需要进行BSW的NvM配置,并可以在APP中使用两种类型的模式进行数据操作,即应用层的Nv Component和内置的NvData Interface。在APP中,可以通过CS接口直接调用NvM的服务接口。数据操作包括周期写、下电写和立刻写三种方式。根据引用\[2\],在Task中调用Nvm_WriteBlock函数可以将数据存储到NVM中,并且会清除Direct Flag和Event Flag。NvM_WriteBlock函数的传递参数一般需要一个永久的RAM(Global的变量.Mirror)。在NvM的MainFunction中可以查看Mirror的状态。NvMWriteRamBlockToNvM函数会将数据放到NvM中,并调用EA或者FEE的接口函数将数据存储到EEPROM或者FLASH中。

Autosar NVM
Autosar NVM (Non-Volatile Memory) is a standard software module that provides a uniform interface to access non-volatile memory devices in an Autosar-compliant system. It enables the storage and retrieval of data needed for the operation of the system, such as configuration data, calibration data, and diagnostic information.
Autosar NVM is designed to be flexible and scalable, supporting a wide range of non-volatile memory devices, including EEPROM, Flash, and FRAM. It provides a set of standardized APIs that abstract the underlying hardware and provide a consistent interface to the application layer.
The Autosar NVM module also provides features such as data integrity checks, error handling, and wear leveling, ensuring reliable and efficient operation of the non-volatile memory devices. It supports both synchronous and asynchronous access to the memory, providing flexibility for different use cases.
Overall, Autosar NVM is a critical component of an Autosar-compliant system, enabling reliable and efficient storage and retrieval of critical data.
