Teensy 4.1

[wtinelli22]

Hi all,

I am a member of the Florida Tech rocketry team and we are currently writing a PDR and need to create a qualitative fault tree analysis. Now, the Teensy 4.1 we are using is going to be the redundancy computer on our rocket, and while we can't necessarily test it a bunch of times, we can get the data from a fault tree analysis from the manufacturer and use that to determine the chances of failure.

I was hoping someone could help me find this or lead me in the right direction.

Thank you,
Wyatt

I do not think you are going to be able to find a "fault tree" analysis for any of these boards especially if you are planning a formal PDR. I have never seen one. You would have to generate one on your own from scratch and not sure where you would start. A lot of things will probably be hanging off these boards that could cause a processor fault or failure.

Sorry couldn't be of more help
