Problem Installing LaunchPad Drivers

Philip,

 

I suggest you go to the device manager (Do Start-> Run  then type "devmgmt.msc" and press enter). Right click on the launchpad device (or if it's not connected, go to the menus and click on show hidden), Then uninstall and reinstall. You can also force it to take a specific driver by doing an update and telling it that you'll install it manually. Then click on "Have Disk..." and point it to the drivers. This will force it to replace them.

Gustavo,

Thanks for the reply. I have looked in Device Manager for the LaunchPad, but the only things I see when i plug it in are "Composite Device" under USB Controllers, and "MSP430 Application UART(COM8) under Ports (COM &LPT). Where do I find the correct drivers for these? I've tried uninstalling and letting windows re-find the device, but that's when I get the "USB Device Not Recongnized" messages.

Do you have a link to the correct drivers?

It is the "MSP430 Application UART" that you need to uninstall.

Yes, I have uninstalled that device a couple of times. Once I plug the LaunchPad back in, it reinstalls. I'm not getting the "USB Device not Recognized" bubble anymore, BUT I am having problems programming the board in CCS. When I try to debug/program the chip, it goes through the compile/build process, then stops and gives an error saying:

 

"Exception occurred during launch

Reason:
Faild to load program 'Temp Sensor.out' on target 'Data snapshot viewer/MSP430'.

Reason:
Cannot write to target.'

Also, in the console view, it says:

"MSP430: Trouble Writing Memory Block at 0xf800 on Page 0 of Length 0x5b2: This operation is not supported by this driver"

Thoughts?

 

 

Philip,

I'm sorry to say I've faced that same issue myself (and I still am). The partial fixes that have worked for me are to do the update driver and force it to a new driver. If you do uninstall, it automatically installs it from the windows directories, so you're not getting a clean driver. Other things you can try are switching the port in which you have the FET connected.

Hello,

I also have seen this problem. In an attempt to resolve the issue, I installed the CDC backchannel UART driver as suggested on the page:  http://processors.wiki.ti.com/index.php/MSP430_JTAG_Interface_USB_Driver - ran the preinstall.exe and then right clicked on the .inf and installed. No feedback but the drivers did install.

Afterward it was slightly different but still not working. Instead of displaying the "MSP430 ...UART" message in the PORTS group, it displays "Unknown Device": in the USB device group. Attempting to "update driver" from the device management console, it says that there is no newer driver required. 

I'm at a loss as to what to try having also uninstalled the drivers, removed the corresponding entries the .inf file makes to the registry, and deleteing the driver files it drops in the windows directories. Then reinstalled the latest code composer download from "help/check updates".

So my question is - what version of code composer are you running that is working? I know with the JTAG USB FET pod, there were some versions of CCS4 that did not play well with the pod. Could this be a similar problem?

Also, CCS4 went from complaining about not being able to program the FET to now complaining that there is no FET found.

What drivers, versions etc. do you have working?

Thanks

 

i'm having similar problems....  i just installed the latest CCS to use with my new launchpad....  but when i plug in the launchpad, windows doesn't seem to recognize the device; and i don't see any entries under COM ports in the device manager....

i've tried to manually install drivers from the TI site, but no luck....

did you eventually solve this problem???

Hi, I got to messing around with this problem today, and I couldn't get the device driver to take properly and it kept failing on the MSP430 Application UART driver. The fix for me was to edit the 430cdc.inf file so that it says CopyFiles=FakeModemCopyFileSection in each of the sections (32bit and 64bit) and then try to install again with the modified inf. Hope this helps.

same problem.
my windows also can't recognize the MSP430GP401R LaunchPad.
where can i download the drivers manually >>?

Where can I find the drivers ?

The latest drivers are installed together with IAR or CCS. However, if you plugged your device into the PC before software installation, you need to uninstall the device from the device manager. Unplug it, the plug it in again and see what is added. Delete all devices that pop-up when you plug-in the LaunchPad. Then remove and attach the LaunchPad again. This time, the proper device drivers should be used.

The drivers are also available for single install in a sub-folder of CSS (for client-only systems without compiler). And IIRC you can load them from the TI website too, but don't ask me for the link.
