Hi all,
I am currently designing a PCBA for the Raspberry Pi 5, so the the Pi can run from an SSD (via PCIe). So far the job seems quite easy, because of the nice documentation (it is a lot of fun actually, I wished this was the usualy case). However as I am more a hardware guy, I was wondering whether the Raspberry Pi OS can handle small disconnect times without crashing.
For explanation: I want to boot the Raspberry Pi 5 only from the SSD, no SD Card attached. The SSD PCBA will have it's own power supply and I also want to see how long the FFC cabling can be.
This leaves me wondering, what would happen, if there should be a small disconnect (either a short power fail on my PCBA, some common mode distorion due to long cabling, minor ESD strike, ...).
Does the Operating System run from the SSD or from RAM, once it is booted up? Or in other words: Will there only be delayed/failed file reads and writes or will the Operating System crash as a whole, when there is a short term disconnect from the SSD (usually the connection on a PHY level should recover I suppose).
I am not having issues yet, but I'd like to be prepared for such things and maybe solve them on a hardware level or be able to handle them on a software level through some configuration tricks of the OS (hints are appreciated here![:)]( "Smile")
).
Thanks for your help!
Cheers Daniel
