here is my question :
Is it ok to prepare an SD card like adding software, ugrading SD card on RP2/3 then run it on RPi4, or the other way round ?
I have 2 SD card prepared on a RPI3, then installed on a Pi 4 that crashed. Some other doesn't seem to crash despite having been prepare the same way. But as the crash happen after a while, the last one might crash sooner or later ?
I wonder if I do something wrong, or if my SD card are not reliable, or if doing like I did isn't a good practice ?
