Re: [Mspgcc-users] How do you get an ez430 going under Linux?

[Steve Underwood]

Hi,

If you have a recent kernel, the USB FET tools should just work. 
However, some distros don't have hotplug set up properly. You may need 
something like a file called /etc/hotplug/usb/ti_usb_3410_5052 containing

#!/bin/bash
BOOT_CONFIG=1
ACTIVE_CONFIG=2

if [[ "$ACTION" != "add" ]]
then
    exit
fi

CONFIG_PATH=/sys${DEVPATH%/?*}/bConfigurationValue

if [[ 0`cat $CONFIG_PATH` -ne $BOOT_CONFIG ]]
then
    exit
fi

PRODUCT=${PRODUCT%/?*}               # delete version
VENDOR_ID=`printf "%d" 0x${PRODUCT%/?*}`
PRODUCT_ID=`printf "%d" 0x${PRODUCT#*?/}`

PARAM_PATH=/sys/module/ti_usb_3410_5052/parameters

function scan() {
    s=$1
    shift
    for i
    do
            if [[ $s -eq $i ]]
            then
                    return 0
            fi
    done
    return 1
}

IFS=$IFS,

if (scan $VENDOR_ID 1105 `cat $PARAM_PATH/vendor_3410` && scan 
$PRODUCT_ID 13328 62512 `cat $PARAM_PATH/product_3410`) ||
  (scan $VENDOR_ID 1105 `cat $PARAM_PATH/vendor_5052` && scan 
$PRODUCT_ID 20562 20818 20570 20575 `cat $PARAM_PATH/product_5052`)
then
    echo $ACTIVE_CONFIG > $CONFIG_PATH
fi

Is there any documentation on using an ez430 under Linux?

When I plug in my ez430, I don't get a corresponding
/dev/ttyUSB device. Google found this page, which describes the
symptoms exactly:

http://people.ee.ethz.ch/~npreyss/msp430/

The solution it describes is this:

   Notice: Your output may vary regarding different usb device
   names. The problem results from a wrong USB device
   configuration selected. You can manually fix this by:

   # echo "2" > /sys/bus/usb/devices/2-1.1/bConfigurationValue

Except I don't have a "bConfigurationValue" file:

  # tail -n4 /var/log/messages

I'm using the "stock" driver from the Gentoo 2.6.22-r5 kernel.
