i.MX RT1170 ECC Application
●i.MX RT1170 covers auto area, so, compared with previous i.MX RT product like i.MX RT1060, the ECC feature is enhanced a lot. For use case with high safety level requirement, we need to detect the ECC error when it happens and informs application system to decide how to process this error.
●This document discusses the ECC application on memory, including TCM, Cache, OCRAM and external memory, and shares some key points and experience. It does not cover ECC application on peripherals like FlexSPI, Fuse, OCOTP, CSI, MIPI CSI, MIPI DSI, ENET QOS and FLEX CAN.
●For memory ECC application on i.MX RT1170, we need to consider:
■On which memory to apply ECC?
▲i.MX RT 1170 contains the following memory types:
◆TCM
◆Cache
◆OCRAM
◆External memory
■How to inject/capture ECC error?
■Fuse setting and SW configuration related with ECC.
■ROM feature related with ECC.
