Upgrading the Pi

[Jonnan001]

My apologies. Bought the Raspberry Pi 3b, and it works great.

So much better than my Raspberry Pi 2b that I finally decided that the slow way it ran wasn't just me having unrealistic expectations, but that it really should run better. After some googling and eliminating some possibilities, I finally checked the CPU itself.

Yeah - Frye's sold me a 1b+ in a 2b package. I did this just as the 2b came out, and I'm guessing there's someone with a '1b+' that works *great*. Kinda ticked, kinda nonplussed, kinda relieved that I really *wasn't* that far off on what my pi should be able to do. Certainly too late to return it.

My question is, given the difference in hardware, if I buy another 3b, can I just pull my SD card and have it run fine in the 3b, or should I assume I need to setup everything from the ground up again?

If you start by doing "sudo apt-get update" and "sudo apt-get upgrade" in that order, your old card should run on the 3B. If your old card is running Raspbian Wheezy, you'd be better off to start over again with a new install. Just save off any user data you want to keep, take notes about non-default system settings you've been using and any packages you installed that aren't already in Raspbian Jessie that you want. If you keep the old card, you can mount if later (use an SD card USB adapter) to grab anything you missed and if you keep the old board handy, you can boot it with the old card to check any software or settings you might have missed.

Old programmers aren't paranoid. They just know (like any other kind of Engineer) that the universe is out to get them. Backups and data retention are a way of life...

Thanks - it's actually a fresh install because a prior copy of raspian had issues and with the new 3b I went ahead and ported stuff. The fresh Raspian helped some stuff but was still *so* much slower than 900mhz vs 1.2 ghz explained that I started digging in.

Now of course I'm miffed that I didn't listen to my intuition when I bought it; My only excuse is 'Well, it *worked* it just didn't work the way I expected ...".

So next paycheck I'll probably move an old SD card over to the 1b+ and keep using it for btsync and as a calibre server, and move the 32 Gb card over to a new 3b and use it for email/web browsing and old games like I originally intended.

Raspberry Pi 2b or not 2b. Okay, it turns not 2b - {G}.

What does the board actually say on it?

[Jonnan001]

Unless you're offering to upgrade it I'm not admitting I just unscrewed the casing and it says Raspberry Pi Model B+ V1 2 big as life there on the PCB board.

Because that would imply I took all this home, screwed it together in a pretty black case, had it sorta work for what, 18 months, finally checked the CPU from the command prompt, and never once actually noticed the board didn't match the package I bought till somebody on the internet asked if I'd ever looked.

What kind of idiot would do something that stupid? Not *me* surely! I have a three digit IQ, I have tests to prove this so *you* sir are thinking of some *other* guy. Everything's perfectly all right now. We're fine. We're all fine here now, thank you. How are you?

You can tell instantly.

uname -a gives you a positive clue.

Apollo is B+, Eagle is 2B, Challenger is a 3B.

PSA: In case someone finds this thread, moving the card from the 1B+ to the 3B worked exactly as advertised. Found the internal wifi chip and connected to my wireless like a champ.

Minor Problems: Volume control is not affecting the Analog output (worked before, so that's odd).

For some reason Vice (Which was working fine on the 1B+ under Wheezy?) seems to not exist in the repositories anymore; despite the fact that it installs fine on the RetroPie(?). Hatari and Dosbox install fine so not sure what is going on there. I suppose if I want to listen to Tubular Bells I'll need to run it in RetroPie.

Other than that - Epiphany runs great, Firefox installed and runs slowly but stably, and I can play Moo II and wasteland. Definitely the improvement I was hoping for.

Thanks all,
Jonnan

That looks like an issue with the Raspbian build. Vice for armhf is included in the Debian Jessie repo, so I'm not sure why it isn't in Raspbian.
