Linux toolchain in an Ubuntu 12.04 32-bit Virtual Machine

You may remember from my last post that I can't compile Maple on my laptop because of strange conflicts with other things on my system. I thought it might be nice to set up a virtual machine to circumvent these problems (and I also feel much more productive in Linux than I do in Windows 7 so there are other benefits as well!). Here's what I've done so far:

1. Made a 64-bit Ubuntu VM with VMware and an ubuntu 12.04 ISO
2. Ran into weird errors relating to some things being 32-bit and others being 64-bit
3. Made a 32-bit VM
4. Followed the instructions here: http://leaflabs.com/docs/unix-toolchain.html
5. Successfully compiled main.cpp.example
6. Successfully compiled examples/test-session.cpp main.cpp
7. But it won't upload with make install even when the Maple is in continuous bootloader mode.

Here's the output:

@ubuntu:~/libmaple$ make installInstall target: flash
./support/scripts/reset.py && sleep 1                  && dfu-util -a1 -d 1EAF:0003 -D build/maple.bin -R
Could not find Maple serial port; defaulting to /dev/maple.
Using /dev/maple as Maple serial port
Failed to open serial port /dev/maple for reset
dfu-util 0.5

dfu-util does currently only support DFU version 1.0

How can I fix this? I think the VM is blameless because the Maple is definitely getting all the way to ubuntu; if I unplug it I get a different error (Device not found).

This post seems to indicate it might be dfu-util: http://forums.leaflabs.com/topic.php?id=1369#post-8304

But I added torm's PPA and tried to update it to no avail. Apt-get says dfu-util is already the latest version even though dfu-util --version returns 0.5.0 and the one on torm's PPA is 0.8.0!

UPDATE! Fixed it! Download the latest release tarball from here: http://dfu-util.gnumonks.org/ then:

tar xvzf dfu-util-0.7.tar.gz 		# Extract
cd dfu-util-0.7/			# Enter Directory
head -100 README 			# Read README
sudo apt-get build-dep dfu-util		# Get build dependencies
sudo apt-get install libusb-1.0-0-dev   # More build dependencies
./autogen.sh 				# From here: http://dfu-util.gnumonks.org/build.html
./configure 				# Also from ^
make					# Compile
sudo make install			# Install
dfu-util --version			# Check the version, should be > 0.5.0
cd ~/libmaple/				# Go back to the maple dir
sudo make install			# Try install again, should succeed!

The Maple bootloader firmware has a bug (although now fixed in the code repository), and dfu-util 0.6 and newer includes a workaround for this bug. This because many people will have difficulties upgrading their Maple firmware.

I think you did not add the PPA correctly. You must specify "lucid" even if you use something newer. What does apt-cache policy dfu-util say? Note also that the PPA has 0.7, which is the latest release.

If you build it yourself, please also try the latest code from the git repository. Replace the above download and tar command with git clone git://gitorious.org/dfu-util/dfu-util.git. I hope to release 0.8 soon and testing is always welcome.

Your instructions above are nice, but do you need "sudo" on the libmaple install?
