The default user/password for the standard
PI distributions (wheezy and raspbian) are pi/raspberry. You can’t log in
as root, unless you set a root password, via sudo passwd. Sudo doesn’t
need a password.
The SD card has a small boot partition,
formatted as a FAT partition, so can be seen by windows. The rest is ext4,
which windows can’t see, So a freshly loaded image appears to windows as
around 55 MB. When first booted, it will only use the first 2 GB. The first
time you log in it should run a utility raspi-config, which allows you to
resize the root partition to fill the card.
My main interest is in using the pi as a
packet node. The prototype TNC is shown on the front page of this group. This
is a standard TNC-X, with a bit of stripboard superglued to the edge to carry a
26 way connector. I’ve designed a board with the connector on board, and
the same size as the pi. I’m waiting for the boards to come back from the
PCB factory. The board is stackable, so more than one TNC can be connected, and
uses the i2c bus to communicate with the pi.

[Raspberry_Pi_4-Ham_RADIO] Some progress
Hi
again,
Having
somehow locked myself out of the second OS installation (it's demanding a
password, which I didn't set) I decided to format the 8Gb card and reinstall
the OS. My laptop now reports that it's a 55.8Mb card. Any suggestions?
My box of bits arrived yesterday. The HDMI-to-VGA converter works a treat. I
can read all the text on the computer's monitor (when it's not moving too
quickly) and have a full view of the games screens.
The
26-way connectors and cable arrived too, so I can start making leads for the
P1 GPIO header. First job; flash an LED. Second job; flash it in Morse!
