Unable to get device serial number

[gregcotten]

OS X 10.8.2
I installed libusb by doing:

$ brew install libusb

I plug in my Stellaris Launchpad to the debug USB and am getting this everytime I try to flash it:

$ ./lm4flash/lm4flash project0.bin 
Unable to get device serial number: LIBUSB_ERROR_OTHER
Unable to find any ICDI devices

I get this if I unplug it:

$ ./lm4flash/lm4flash project0.bin 
Unable to find any ICDI devices

Hi

Could you please check if this workaround works for you:

https://github.com/zyga/lm4tools/tree/develop

It will work as before and if you have just one board attached it should just work

Greg,

Please build lm4flash with DEBUG enabled. Uncomment the line #define DEBUG 1 which is commented out in the code. This will provide some extra info. Also it would be nice setting libusb debug. Please insert the following line just after the call to libusb_init() in the code:

libusb_set_debug(ctx, 3);

Then provide the output here. With that info we'll able to see what's happening and fix the issue.

[utzig]

Greg,

Please try the following. Download this file:

http://utzig.net/files/lm4f120_icdi.tgz

Then unpack it at /System/Library/Extensions.

$ cd /System/Library/Extensions
$ sudo tar xzvf ~/lm4f120_icdi.tgz

Need to be root to do that! Touch it:

$ sudo touch lm4f120_icdi.kext

Wait some time and try running lm4flash again. If this fixes your problem please let us know!

[gregcotten]

The one at commit cc49426 uploads fine. Should I still try the kext?

[utzig]

That version you mentioned works because it didn't use the board serial number (uses another type of usb request). Other people are already testing this on Mac OS X now so if you're fine with that older version you could keep it. But new versions/features will most probably require this driver. It was already tested and it seems to work ok.

This is from the newest commit. This is what happens when I try to upload project0.bin after I compiled lm4flash with debug enabled and added libusb_set_debug(ctx, 3);

.kext works great by the way! Now time to add this to the Readme!

[utzig]

As soon as other issues are fixed, it will. Thanks!

[mattwilliamson]

This works for me on Mountain Lion too. Thanks!

[letaage]

Hi there,

lm4f120_icdi.kext fixes the problem with not being able to find serial numbers for the Stellaris Launch Pad on Mountain Lion, but it causes trouble with other USB devices on my system. In particular, the Nokia Device Browser 1.9.1 (62) software that I use to transfer files to and from my phone.

With lm4f120_icdi.kext installed in the /System/Library/Extensions folder, the Nokia software keeps throwing an error when I connect my phone (Nokia E55) that the device doesn't support some mode of operation and I'm no longer able to access the phone.

When I remove lm4f120_icdi.kext the Nokia software works properly.

I am using lm4flash v 0.1 and libusb 1.0.9_0 (installed via macports) on OS X 10.8.2

I can provide more information if you need anything in particular, just let me know.

[utzig]

@letaage The driver should only be responsible for devices with VID=0x1cbe and PID=0x00fd. Could you confirm the VID/PID used by your Nokia device without lm4f120_icdi.kext installed?

[letaage]

It comes up with:

Product ID: 0x01d4
Vendor ID: 0x0421 (Nokia Corporation)

And the problem persists, however it seems more reliable if I don't connect my phone via the keyboard USB hub, which is weird because it's been working fine for years.

Also strange that the problem only started when I installed the kext - probably just one of those unfortunate coincidences. I'll keep an eye on it for now.

[jammi]

utzig: Thanks, you kext fixed the original issue I had too.

[thefloe1]

Hi,

for me under OSX 10.8.2 the problem still exists. Debug log looks just the same as posted above. The link for the kext is not available. I already tried the developer version linked above without success.

Is there a new workaround available or can someone please re-upload the kext?

Thanks

[utzig]

@thefloe1 You can get it here:

http://69.55.60.135/files/lm4f120_icdi.tgz

I changed the DNS so the name doesn't point to the same place anymore. Btw, I'll add the sources for this to the project tomorrow (if I don't forget...) so anyone can build it.
