booting rev 2 boards

[jamargevicius]

I am trying to boot up my rev 2 A+ (and rev 2 B)... I am using NOOBS, but it comes up with the ERR: Resizign exiting FAT partition. I have followed the suggestions in this forum to "make sure the SD memory is formatted properly" -- I have 3 chips (2 are 32 G, and 1 is 16G) and have used SDFormatter to format them to FAT32, Full (Overwrite), Yes to auto size --- and EaseUS to do the same. Then I have carefully copied NOOBS v1_4_1 to the "drive" using Windows 7. Then I insert it into A+ or B (rev2) and watch it boot up, get into X-term, but then complain that there is 0MB for applying the OS. I had no such problems in loading my rev 1 boards ! .. they work fine. This is a problem with the new A+ and B rev2 boards.

What is happening? This is frustrating, and I am at wits end -- don't know what to do. Any help is appreciated. I have

11/24/15 --- answer to query -- basic idea was to move from the Rev 1 boards to the Rev 2 boards without having to re-edit the various system files specifying the wifi connection/password, font colors, prompt, how to "come up" , printer, etc.. The info I got from the web was not useful, in the end. Also, I screwed up "as a newbie/smartie" in realizing that whoever developed the Win32 Disk Imager was in a different generation that me (when you want to "open a file", it's not intuitive, duh, that you're supposed to put the name of a "brand new never created" file in the box ! ... am I just too old for this faux-logic ? ... you open up a file, only if it already exists! ... which of course it didn't, so I was lost.). So, once I figured out this faux-logic, I was able to create the .iso file and transfer it to the new A+ Raspberry Pi. I hope this helps the next poor soul. ... in the end, it's easier to just re-do the /etc/default/keyboard, /etc/hosts, ~./bashrc, and ~/.dircolors .... than to try to move the Rev 1 files to the Rev 2 image.

You do seem confused.

NOOBS is the operating system loader. You use a blank SD card (reformatted as in your first post using SDFormatter) and do a simple copy of the NOOBS files on to the SD card, just as you would copy any other file. You put this card in the Pi and switch on the power. The Pi starts up and runs a special NOOBS program that allows you to select an operating system, which it writes to the card, and it then reboots the Pi into that operating system.

The Win32 Disk Imager takes a specially created files (a .iso file) and does a special write to the SD card. The Win32 Disk Imager will also create those files, as you have found. The resulting SD card now contains all the files and partitions (i.e. structure) of the operating system that you specified when creating the .iso file (or image).

You shouldn't mix up the two methods, both in your head and on a card. Both will wipe out whatever you have on the SD card when you start them. The cards you use for your Pi "should" (see note) be able to be used in any Pi, so you should not need to 'update' the SD card to use it in a different Pi. Of course, if you use different keyboards and monitors, the settings for those might need to be changed.

Note: since the release of the Pi 2, the cards contain a "kernel" (the main code that runs the Pi) created especially for the Pi 2. This does not exist on cards from before that date

Note2: You might have hit the problem of formatting a 32GB card; the card needs to be formatted as FAT, but cards over 32GB are generally formatted as exFAT. What you did does not sound like you did, but the "0MB for applying the OS" does suggest that the formatting is not correct (the "get into X-term" is probably the NOOBS loader screen)

FWIW, My notes on "NOOBS Installation (Version 1.4/P2B)" using a Windows 7 m/c etc. can be found here:

(There are other sections within my webpages for earlier versions of NOOBS and older Pi's too.)

Thank you Trevor and Navyscourge for your words --- at this point, I am quite satisfied with my install, and I'm happily in python-land. I wish I had your words a month ago! ...I will say that my initial post was the result of doing very much like what both your posts are stating -- I had downloaded both the "lite" Noobs.zip and the full one, and did the "simple copy" to a blank SD card of the unzipped versions (the SD card was formatted exactly like you show Trevor in your tutorial - FAT, etc - multiple times!; I probably followed your tutorial carefully before writing my 1st post!). After NOOBS booted to the GUI, it came with with the 0 space. When I finally gave up on NOOBS and downloaded the Raspian-Jessie zip file, and used the Win32 Disk Imager to move the .iso file to the blank SD card, my problems went away. It is still possible I did something stupid while playing NOOBS (I understood pretty clearly what NOOBS was about), but f you could figure out what I did wrong, I think it could be a help to others. In the attachment, I show what the folder contained after unzipping the downloads. Thanks for you time.
