My web"nozing" told me that the two (the Rpi1B 256 and 512) variants are virtually the same hardware spec-wise (with the exception of the amount of RAM ofc. and maybe the SMT/cirquit layout).
- Could I simply take out the SD card (running Raspbian wheezy) from the 256MB one and place it into the 512MB one (any snags to be expected)?
- What about the other way around (start with 512, cutting back to 256)?
I would expect the OS to be "smart" enough to "adapt" to the extra (or less) amount of RAM. But does it?
