PI3 Question

lcipir

Hello, I recently purchased a PI3 to use in one of my existing projects and the initial research I did led me to believe that the PI2 could be upgraded to PI3 by swapping out SD cards.  I got a PI3 from Adafruit and it would not work (4 slow blink followed by 4 fast blink ACT).  I asked them and they said that the PI3 has recently gone through a change that makes it not compatible with the PI2 OS.   The reason why I am asking is because my project is long and complicated and I would not want to have to redo the entire thing to go to PI3 since I made the project on PI2.  Any help feedback would be most appreciated.

Thanks,

Dan

  • I'm not sure where you got the impression from but the Pi 2 and Pi 3 use different ARM cores in the SOC. The Pi 2 is a 32 bit quad-core ARM and the Pi 3 is a 64 bit quad-core ARM

    although most of the current OSs run it in 32 bit mode. Most of the differences between the two should be "hidden" in the OS which is why you need to upgrade to the latest version

    when running the Pi 3. The good news is that most of the hardware outside the ARM core in the SOC is the same and any software written to use that hardware should continue to

    work although it may occasionally require some small tweaks to do so.

    I do not understand the impression you think I got?

    I was simply using a PI2 and thought it would be nice to upgrade hardware to PI3.  Did research and on these forums others said you could go from PI2 to PI3 hardware.  I found I could not which is why I am posting.  If it was just doing the software upgrades, understandable.  I thought mine was pretty up to date but it took more so it was worth that attempt for sure.
