Beagleboard Interface with MSP430 Launchpad

[Siddharth Kumar]

My Beagleboard is Running Angstrom Linux 3.2.18 Kernel:

i was able to compile the the modules for the 3.2.18 kernel and now i have three packages

kernel-module-ti-usb-3410-5052.ipk

kernel-firmware-ti-3410.ipk

kernel-firmware-ti-5052.ipk

kernel-module-cdc-acm.ipk

i did opkg install for all these packages and then ran

root@beagleboard:/# modprobe ti_usb_3410_5052 vendor_3410=0x0451 product_3410=0xf432

[ 23.988830] usbcore: registered new interface driver usbserial

[ 24.043792] ti_usb_3410_5052: v0.10:TI USB 3410/5052 Serial Driver

After that i inserted the launchpad and i get this output on the screen..

Am i missing some firmware ? where can i get this from? 

I am using Minicom to communicate with the Beagleboard and am running Ubuntu 12.04 on my Host machine..

Thank you for any help ..

I don't remember for sure if those messages are an actual problem. You
seem to be getting the UART and HID devices for communicating with the
target and programming it.

Have you tried using them? Does it fail?

Did you know, you can just use GNU screen(1) and ignore all the
useless modem bits and odd UI that minicom brings in? :)

Right now im just trying to read the data being sent from the Launchpad ...

the command "screen" is not recognized by the beagleboard .. If i try 

stty 2400 -F /dev/ttyACM0

cat /dev/ttyACM0

i dont get any output ...( where as the exact same thing works on my host Ubuntu)

Thank you for your quick reply :)

I am a lil new to all this so sorry if some of my questions seem stupid.. 

[Siddharth Kumar]

Sorry i think i misunderstood you i guess you were asking me to use screen on my host pc to communicate with the beagleboard ... 

Im using that now thanks for the tip .....

But i still dont get any output on using 

cat /dev/ttyACM0

You could download (or compile) a beagleboard-compatible version of
GNU Screen to run on the board.

I haven't worked with serial on embedded Linux lately, but as I
recall, you'll have to set the serial parameters for the beagle's
serial port via setserial. I think stty only applies the setting
until the port is closed- when cat reopens /dev/ttyACM0, the kernel's
defaults are taken.

And I'm pretty sure the launchpad speaks faster than 2400 by default.

I'd recommend working out how to talk to the launchpad from your
Ubuntu PC (host) to get the parameters right, and then make the
appropriate settings on the Beagle.

Thank you so much sir let me try it and will surely revert back with the feedback

[Siddharth Kumar]

Thank you all for your input ! :)

I got it working using microcom from the Busybox tool set :)!

#microcom -s 9600 /dev/ttyACM0

Thank you once again !

Hi,

I have been trying forever to read the same board on OpenWRT.

Would you care to share some of your results? For example, what is your "lsusb" config? And what happens when you run that microcom command? Any good tests I can use?

And I guess you never got past that "error downloading firmware" problem for the ti_usb_3410_5052 driver (which I assumed was THE standard way to go).

Thanks for any help...
