OverviewAt my job, I was recently tasked with handling ECC errors in both RAM and flash memory. Additionally, I needed to test the error handling by injecting ECC errors. Figuring out how to do this was a nightmare. I looked over AN5342 countless tim...

MCU: STM32H753VI Scenario:I am working on the error management system for our firmware. Part of that is handling ECC errors in flash and RAM. I have been able to successfully inject and handle flash ECC errors, but am having trouble with RAM ECC. Pro...

MCU: STM32H753VI Scenario:Requirements specify that I must use internal flash memory to store error counters for our fault management system. I was going to directly write to flash memory using the built in HAL commands, but found that most people se...

Hello,I'm glad the guide was able to help.The behavior you are seeing with the memory analyzer aligns with what I was seeing. Out of curiosity, what sort of application are you working on that requires handling ECC errors?- Jared

Hello @SofLit,I authored the post you linked, is that really the recommended way of triggering a ram ecc error? I made the post because it was literally the only way I was able to figure out how to inject an error. Any feedback would be appreciated.-...

Hello,Thanks for the response! I was not able to find anything about how to enable the RAMCFG clock, could you please provide more detail on that?Additionally, is there any example code I could look at for generating RAMECC errors?Thanks again,Jared

I ended up getting flash ECC figured out, thank you so much for your help! I'm now working on testing RAM ECC, but am having trouble triggering ECC errors. Is this something you have encountered?Thanks again!
