New Maple user - device not recognized in Linux

Hello,

I'm newer to the microcontroller scene, and reletively new to the Linux scene, but I decided to work with Maple in Linux because it seemed nicer.

I received my Maple r5 in the mail yesterday, hooked it up and everything was working beautifully. In the IDE, I chose the correct serial port (there was only one: ttyACM0) and board. Then with the Blink sketch open, I simply uploaded it to the board. The led on the Maple flashed a few times, then it turned off for ever (no blinking from the sketch). So, I figured whatever, and tried uploading again. This time no flash AND ttyACM0 was removed from my available Serial Ports list. As I unplug and replug in the USB or hit Reset on the board, my dmesg reports:

[66437.136103] usb 2-1: USB disconnect, address 9
[66450.220067] usb 2-1: new full speed USB device using uhci_hcd and address 10
[66453.256183] usb 2-1: USB disconnect, address 10

I'm not exactly sure what this means except that it's not what should be happening.
Also dfu-util -l reports:

dfu-util does currently only support DFU version 1.0

Which I also don't think should be happening...
I've tried perpetual bootloader mode and resetting multiple times (the LED flashes correctly every time) with no luck.
I'm running Ubuntu 11.04 32-bit.

Any help would be appreciated. Please let me know what I can tell you to help me.

Hi freiguy1,

Sorry to hear you've been having problems. I think some other users have also reported issues with Ubuntu 11; we do our testing on 10.04 and 10.10, so it seems likely that there are some software updates we haven't caught up with in Ubuntu 11.

Some questions which can help us proceed further:

1) Is the report from dfu-util -l coming from the dfu-util that comes with Maple IDE, or did you install one yourself? (The version that comes with Maple IDE lives in hardware/tools/arm/bin/dfu-util within the IDE directory).

2) What does dfu-util --version tell you?

Thanks for the reply!
the dfu-util comes from a program that I installed, since that's what I thought people were using.

So the system dfu-util --version:
dfu-util - (C) 2005-2008 by Weston Schmidt, Harald Welte and OpenMoko Inc.
This program is Free Software and has ABSOLUTELY NO WARRANTY

dfu-util does currently only support DFU version 1.0

dfu-util version 0.3

maple IDE's dfu-util --version:
dfu-util - (C) 2007 by OpenMoko Inc.
This program is Free Software and has ABSOLUTELY NO WARRANTY

dfu-util version 0.1+svnexported

maple IDE's dfu-util -l when board is in normal mode (LED not flashing):
dfu-util - (C) 2007 by OpenMoko Inc.
This program is Free Software and has ABSOLUTELY NO WARRANTY

.. that's it.

maple IDE's dfu-util -l when board is in PBM:
dfu-util - (C) 2007 by OpenMoko Inc.
This program is Free Software and has ABSOLUTELY NO WARRANTY

Found DFU: [0x1eaf:0x0003] devnum=12, cfg=0, intf=0, alt=0, name="DFU Pro"
Found DFU: [0x1eaf:0x0003] devnum=12, cfg=0, intf=0, alt=1, name="DFU Program FLASH 0x08005000"

Ha, probably the only useful bit of this whole post is these last couple lines.

Also this is output when downloading a program when the maple is in PBM:

Reset via USB Serial Failed! Did you select the serial right serial port?

Resetting USB to switch back to runtime mode

When this is completed, the unit's behavior and everything is the same as I've been reporting. Still not attaching to /dev/ttyACM0 and no blinking.

Thanks!

hmm, did you select the correct board from the drop down menu?

Since you saw the serial port when it first came out of the box, the serial port firmware and the OS seem to play nice together. But, since the blinky upload doesnt even blink, it makes me think perhaps the upload is botched. The easiest way to botch an upload is to have the wrong board selected from tools->board

A future feature should be for the IDE to detect what board is plugged in. This would be useful ;)
