Challenges of Tomorrow's Data Storage Integrity in Automotive and IOT Projects
Historically Automotive control units were literally read only. Functionality has been defined by the developer at the very beginning with no major changes over lifetime. Number of write cycles for Flash memory was a no-worry. Now systems become much more complex with ECUs being consolidated into domain controllers hosting multiple functions on one SOC. Introduction of Android makes cars look like mobile phones but with a higher life time of 10-15 years. Together with OTA updates this results in many more write cycles that might make the flash wear out before end of life of the car. Fragmentation suddenly is observed to have an impact on performance at mobile phones. This might break an automotive system if it happens there. Issues like FCA€™s endless loop update from 2018 or the Spotify bug from 2016 with writing 5GB per hour to flash puts further risk on future systems. The paper describes those effects more in detail and suggests measures to mitigate the risks.
