NvM_WriteAll() function, will calculates CRC at a time of writing, if CRC is matches and RAM block status is valid then the corresponding block will not be written into NV memory. The tool comprises of basic AUTOSAR Software Stack and K-SAR Editor. we have been part of the ISO23150 and the AR ADI_SensorInterfaces (not me personally). Dem module uses Nvm blocks for storage DTCs information (status byte, snapshot and extended data). While flashing the software there were no issues and the config block and multi block values are NVM_REQ_OK after few days of running the return value of the blocks are becomes NVM_REQ_NOT_OK. It manages storing application data in EEPROM or flash memory even after power cycles. After I receive the job finished notification in the same or another runnable (TBD), I have to give a response indicating whether this was successful. 2 AUTOSAR Release Management Specify the NRCs to be sent by the Dcm in case of Dem interfaces return negative values.
