Hello gerald
How and where to change these settings on PC and what is terminal
window on PC do I need any software installed? How to send data to
board (where to write and to read)
BAUD RATE: 115200
DATA: 8 bit
PARITY: none
STOP: 1bit
FLOW CONTROL: none
Thank you.
You need a terminal emulation prgram, such as Hyperterm or TerraTerm. You need to launch the program and go to the options to set the parameters in the program. This would also include the serial port on the PC that you are using.

Hello
How do I make partitions on SD card and how do I make images of the
files on the SD card
MLO as MLO
u-boot as u-boot.bin
u-boot for flash as u-boot-f.bin
ramdisk image as ramdisk.gz
Kernel (uImage) as uImage.bin
reset.scr as boot.scr
x-loader image as x-load.bin.ift
Regular script file as normal.scr
Should I just copy those from my computer or is there any thing to
do??
Thank you.
Here is the step by step procedure.

Read it and do exactly what it says. That will result in a bootable SD card. Yes, you will need to do it on your PC.

http://www.xora.org.uk/2009/09/06/improved-omap3-card-formatter/ has
some helpful instructions as well. Also referenced here:

Be sure to copy the MLO file *first*.
Hi,
Here is the step by step procedure.
Google Code Archive - Long-term storage for Google Code Project Hosting.
Read it and do exactly what it says. That will result in a bootable SD card.
You can't follow the instructions exactly, because they are
inconsistent. For Rev C4 board owners there's a note saying:
'NOTE: If the board is a Rev C4, use the files located here
http://www.angstrom-distribution.org/demo/beagleboard/ instead of the
ones listed above.'
but on the recommended page several files are missing ( u-boot for
flash, ramdisk image, reset.scr and 'Regular script file')
Are they obsolete? Shall the C3 files be used instead? Are they
provided by other hidden repositories on the internet? Google doesn't
know about any "ramdisk_revc_v4.gz" file.
On the other hand on angstrom-distribution.org/demo/beagleboard/ there
are some extra files not known on BeagleboardRevC3Validation page and
sadly without any documentation about how to handle them:
Angstrom-Beagleboard-demo-image....rootfs.tar.bz2,
config-2.6.32-r70...beagleboard.config,
modules.tgz
...
Are any of them needed? All? Some?
It would be much easier understandable to give the user a list, which
files to copy where from for Rev C4 boards as done for C3.
Finally, what was working for me:
In my normal PC:
Formating the SD-card with the provided mkcard.txt script
Downloading the following files from http://www.angstrom-distribution.org/demo/beagleboard/
to a local directory and copying (in this order) to the SD card's
partition1:
MLO
u-boot.bin
uImage (You have to keep the name! Renaming to uImage.bin resulted in
'uImage not found' error)
x-load.bin.ift
Powering on the beagleboard with SD card plugged in and pressing USER
button this did succeed in loading the kernel, but was ending up in a
kernel panic because of missing init.
So copying
Angstrom-Beagleboard-demo-image-glibc-ipk-2010.3-
beagleboard.rootfs.tar.bz2
to SD's partition2 and unpacking there
# tar -xjvf Angstrom-Beagleboard-demo-image-glibc-ipk-2010.3-
beagleboard.rootfs.tar.bz2
provided the missing init and resulted in a usable Angstrom
installation.
After extracting the tar.bz2 can be removed.
minicom console still moans for some missing files :

Where can we get user.scr and ramdisk.gz?
