msp430g2 Cant connect via USB

Recommended Posts

Hello everyone,

 

FIrst - its not the permission issue of not having a proper udev rule.

 

 

I am on Debian Wheezy with all the msp related packages installed from the official repos - including mspdebug. But after I connect the launchpad and give:

mspdebug rf2500

I get 

usbutil: unable to find a device matching 0451:f432

My computer is not detecting the board. The output of lsusb is:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 003: ID 1210:25f4 DigiTech 
Bus 002 Device 003: ID 04f3:0232 Elan Microelectronics Corp. Mouse

I get *no* information at dmesg while I plug in or disconnect the launchpad. Absolutely nothing.

 

The output of

lsmod | grep ti

confirms that the ti's usb driver module has not been loaded.  So I manually loaded that one with 

modprobe ti_usb_3410_5052

Now I see something in dmesg:

[ 1496.709197] usbcore: registered new interface driver usbserial
[ 1496.709227] USB Serial support registered for generic
[ 1496.709266] usbcore: registered new interface driver usbserial_generic
[ 1496.709273] usbserial: USB Serial Driver core
[ 1496.722267] USB Serial support registered for TI USB 3410 1 port adapter
[ 1496.722313] USB Serial support registered for TI USB 5052 2 port adapter
[ 1496.722733] usbcore: registered new interface driver ti_usb_3410_5052
[ 1496.722741] ti_usb_3410_5052: v0.10:TI USB 3410/5052 Serial Driver

Now I plugged in the board again. But absolutely *no* change in the dmesg or lsusb output.

 

The board is a fresh one, and its working well - when I plug in into USB, I can see its demo program blinking those red and green leds.

 

Now, as mentioned in http://sourceforge.net/apps/mediawiki/mspgcc/index.php?title=Getting_Started_with_Debugging, I looked for the firmware file to copy, but the file ti_3410.fw doesnt exist anywhere in my /lib/firmware. But I do have a file ti_3410.fw.ihex in /usr/lib/mspdebug which obviously came with mspdebug.

 

What's wrong? What should I do to get the USB port detected? It might be irrelevant, but I can connect an Arduino board on the same port, and it works well.

 

 

Thanks in advance!
