Bob, buy a MicroSD card that comes with the adapter to convert it to
a normal SD card and get that SD<---->USB dongle.
1. Plug the MicroSD card into its adapter.
2. Plug the SD card adapter (with MicroSD card in it) into the USB
dongle.
3. Plug the dongle into your desktop computer and note which device the
SD card shows up as (probably /dev/sdb, but have a look at the output
of dmesg to be sure).
4. Download the ISO that you want.
5. As root, "dd if=name-of-iso-file.iso of=/dev/sdb bs=1M" (assuming the
SD card shows up as /dev/sdb...change as needed)
6. When dd ends, unplug the USB dongle, pull out the SD card adapter,
pull the MicroSD from the adapter, stick it in your RPi and power up the
RPi.
7. Voila!
Well once I knew what to ask for my daughter had a Memory Card Reader, a
"High Speed 55 in 1 card reader" that has connectors for 5 different
types of devices.
Bingo! That's the device!
And I think I can find an SD card in my camera I can
borrow if I don't get one first, so I'm making progress there.
Remember the RPi uses a micro SD card. If the thing your daughter has
has a micro SD slot, you're in! If not, you'll need a microSD->SD
adapter. If that's the case, then just wait and buy a micro SD that
comes with the adapter. Most do.
However
the Raspberry project is secondary until I get this computer done. UPS
delivered the new hard drive late this afternoon, it is installed and I
have F22b installed on it and am in fact typing this message in
Thunderbird from it although it is not completely configured as I want it.
I now have two F22 systems on separate drives, can just select the
drive I want to boot. The only change I've made is to groupinstall
xfce-desktop. The object is to see if this system will display the
iPhone text messages that I can't with the first F22 install.
I guess I should buy at least a 16 gig micro SD card? What is the life
expectancy of one with this use?
Depends on what you're going to store on it. 16G is good enough for most
of what you want to do on something like an RPi. As far as how long
it'll last? About the same as any other FLASHish drive. It's only good
for N write sessions before it essentially goes read-only or
self-destructs ("Good evening, Mr. Phelps...")
If you're going to do a bunch of data storage on the beastie, I'd get a
cheap USB-based hard drive and use it for that sort of thing. That's
sort of what I have on the Jetson TK1--although it has an integral SATA
port. I have the TK1 boot the OS off an MMC card, but all of the heavy
lifting (home directories, /tmp, etc.) is on a cheap 80G 2.5" SATA
laptop drive plugged into the SATA port. It's not pretty but it works
and I'm not worried about running out of write cycles on the MMC while
compiling code on it.
