How do you get an ez430 going under Linux?

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.

Hi,
If you have a recent kernel, the USB FET tools should just work. However, some distros don't have hotplug set up properly.

One of the libraries (HIL or MSP430) was too old. After grabbing the newest versions of both, it's working. Now to figure out why hotplug isn't working.

And when you change it to point to the ez430, the line that does the "echo $ACTIVE_CONFIG" makes the driver hang hard (requires a reboot to get it working again).

It turns out, I should have followed this web page: http://people.ee.ethz.ch/~npreyss/msp430/ The udev approach is a lot easier than using hotplug (especially if hotplug doesn't work on your machine). Here are two udev rules. The first (copied from the above web page) checks the confguration value, and if it's 1 it changes it to 2.

[Since n varies depending on what other USB serial widgets are present, it's nice to have an unchanging reference.] Unfortunately, there's a bug in msp430-gdbproxy. It chokes on the symlink: $ ls -l /dev/ez430 lrwxrwxrwx 1 root root 7 2007-09-24 19:07 /dev/ez430 -> ttyUSB1 $ msp430-gdbproxy msp430 --spy-bi-wire /dev/ttyUSB1 Remote proxy for GDB, v0.7.1, Copyright (C) 1999 Quality Quorum Inc.

Changing the symlink so that it starts with "tty" seems to work.

The stock driver in the 2.6.22 kernel works fine along with the udev rule that sets the configurationValue to 2.

I forgot to include the rule in the posting (it wasn't on the referenced web page): KERNEL=="ttyUSB*", SYSFS{idProduct}=="f430",SYSFS{idVendor}=="0451", SYSFS{bConfigurationValue}=="2", SYMLINK="ttyUSBez430" NB: I've never been able to get NAME="whatever" to work in udev rules, despite folling examples to the letter. However, SYMLINK="whatever" always seems to work. > I didn't find any mention of a symlink in the webpage you > referenced. My bad. Sorry about that. > On my machine (Debian Etch), the command > > prompt> echo "2" > /sys/bus/usb/devices/5-2/bConfigurationValue > > works, however the rule from the webpage doesn't appear to work. I still > get the "probe of ... failed with error -5" error message. Here's what's in my local rules file: KERNEL=="ttyUSB*", SYSFS{interface}=="BitScope 310", SYMLINK="ttyUSB99" KERNEL=="ttyUSB*", SYSFS{serial}=="12345678", SYMLINK="ttyUSBhart" KERNEL=="ttyUSB*", SYSFS{idProduct}=="2303", SYSFS{idVendor}=="067b" , SYMLINK="ttyUSBrs232" SUBSYSTEM=="usb_device", ACTION=="add",SYSFS{idVendor}=="0451", SYSFS{idProduct}=="f430",SYSFS{bNumConfigurations}=="2",SYSFS{bConfigurationValue}=="1", RUN+="/bin/sh -c 'echo 2 >/sys%p/device/bConfigurationValue'" KERNEL=="ttyUSB*", SYSFS{idProduct}=="f430",SYSFS{idVendor}=="0451", SYSFS{bConfigurationValue}=="2", SYMLINK="ttyUSBez430" The last two are the rules for the ez430. And here's what dmesg says when I plug in the ez430: usb 2-1: new full speed USB device using uhci_hcd and address 18 usb 2-1: configuration #1 chosen from 1 choice ti_usb_3410_5052 2-1:1.0: TI USB 3410 1 port adapter converter detected usb 2-1: reset full speed USB device using uhci_hcd and address 18 usb 2-1: device firmware changed ti_usb_3410_5052: probe of 2-1:1.0 failed with error -5 usb 2-1: USB disconnect, address 18 usb 2-1: new full speed USB device using uhci_hcd and address 19 usb 2-1: configuration #1 chosen from 2 choices ti_usb_3410_5052 2-1:1.0: TI USB 3410 1 port adapter converter detected ti_usb_3410_5052: probe of 2-1:1.0 failed with error -5 ti_usb_3410_5052 2-1:2.0: TI USB 3410 1 port adapter converter detected usb 2-1: TI USB 3410 1 port adapter converter now attached to ttyUSB1 Those message are all from a single "plug-in", so I still see the -5 error twice before the adapter gets attached to /dev/ttyUSB1. I'm not sure what all of that means exactly, but the last two lines didn't show up until I added the udev rule that set the configuration value to 2 (or until I manually did the same). And then here's what I see if I do ls -l /dev/ttyUSB* crw-rw---- 1 root uucp 188, 0 2007-09-24 18:44 /dev/ttyUSB0 crw-rw---- 1 root uucp 188, 1 2007-09-26 09:30 /dev/ttyUSB1 lrwxrwxrwx 1 root root 7 2007-09-26 09:30 /dev/ttyUSBez430 -> ttyUSB1 lrwxrwxrwx 1 root root 7 2007-09-24 18:44 /dev/ttyUSBhart -> ttyUSB0 I finally decided to prefix the symlinks with ttyUSB in order to keep all of the USB serial stuff adjacent in 'ls' output. That also has the effect of making gdbproxy happy. -- Grant Edwards grante Yow! Look!

To use this thing was possible right after driver was written (~2.6.11) of course. Question is "how to use". Because they accepted just one very tiny patch to add device ID, now udev rules are a bit smaller. But i want to use the device easily and in Debian. I want to have easily changeable firmware, because windows drivers have newer version of it (and you better don't see ugliness of the sources of the vendor's firmware :). And there are people out there, who wrote their own firmware, because usb chip itself have many additional features. The main problem is linux usb stack, as it is today, after 3 rewrites. Design prohibits driver to change usb configuration of the device. This is because usb driver in linux is not driver of the usb hardware, but usb-interface (as in usb spec.) driver. Changing configuration of the device, cuts trunk of the "driver", and everything falls down. Current usb gate-keeper played dumb with me, when i was trying to discuss this fatal design flaw.

You seem to be saying that after a reconfiguration, the original USB interface disappears, and so the kernel driver loses access to the hardware. However, for USB this should not be a problem---it's the same as if we unplugged the old device and plugged a new one. The driver for the new device should load, and start talking to the hardware on the new interface. At any given steady state point, there should be a driver for each USB interface the hardware presents. How is that bad? ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
