New to beagleboard

Hi,

I received my beagleboard, and I’ve got it powered up and a serial cable connected.

I get the output from the bootloader displayed in HyperTerminal (also in TeraTerm):

Texas Instruments X-Loader 1.41
Starting OS Bootloader…

U-Boot 1.3.3 (Jul 10 2008 - 16:33:09)

OMAP3530-GP rev 2, CPU-OPP2 L3-165MHz
OMAP3 Beagle Board + LPDDR/NAND
DRAM: 128 MB
NAND: 256 MiB
In: serial
Out: serial
Err: serial
Audio Tone on Speakers … complete
OMAP3 beagleboard.org #

and I get teh beagleboard splash screen displayed on my monitor.

But I can’t type anything at the prompt - should I be able to?

Not sure what I’m missing…

Thanks, Steve

You need to make sure you have the right cables, both the ribbon cable and the null modem cable. Take a look at section 12 of the System Reference Manual. http://www.beagleboard.org/uploads/BBSRM_6.pdf . It takes you through the steps to check out the cables.

Steve,

Also check the BeagleBoard community FAQ: http://elinux.org/BeagleBoardFAQ.
The BeagleBoard Wiki http://elinux.org/BeagleBoard has lots of useful
BB information as well.

Hi Steve,

Just a quick reality check: have you tried the cable and the PC with another serial device you know to be working?
If you don’t have anything else handy, you can create a loopback of sorts by shorting pins 2 (RX) and 3 (TX) on the
RS-232 output. Whatever you’re typing on HyperTerminal should come straight back at you. If what you have is not
a “real” serial port (not 16550) but some usb-to-serial converter, I have seen exactly the same problem here. Make
sure you have the correct and the -latest- drivers.

Hope this helps,

Utku

Hi,

Finally got back to this.

I rewired the IDC->DB9 cable i’d scavenged from a box of old pc bits to have just 2-3, 3-2 and 5-5 connected and it now works fine.

Need to get the soldering iron out and tidy things up, its just a mess of stripped and twisted wires at the moment, but hey it works!

Thanks for the advice guys, appreciate it.

Now the fun begins! Really looking forward to the time off I’ve got over christmas for a proper play.

Steve
