This because many people will have difficulties upgrading their Maple firmware.</p> <p>I think you did not add the PPA correctly. You must specify "lucid" even if you use something newer. What does <code>apt-cache policy dfu-util</code> say? Note also that the PPA has 0.7, which is the latest release.</p> <p>If you build it yourself, please also try the latest code from the git repository. Replace the above download and tar command with <code>git clone git://gitorious.org/dfu-util/dfu-util.git</code>. I hope to release 0.8 soon and testing is always welcome.</p> <p>Your instructions above are nice, but do you need "sudo" on the libmaple install? </p> http://forums.leaflabs.com/topic.php?id=74147#post-104921 Thu, 14 Nov 2013 14:24:16 +0000 ftb44 104921@http://forums.leaflabs.com/ <p>UPDATE!

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:</p> <p>1. Made a 64-bit Ubuntu VM with VMware and an ubuntu 12.04 ISO<br /> 2. Ran into weird errors relating to some things being 32-bit and others being 64-bit<br /> 3. Made a 32-bit VM<br /> 4. Followed the instructions here: <a href="http://leaflabs.com/docs/unix-toolchain.html" rel="nofollow">http://leaflabs.com/docs/unix-toolchain.html</a><br /> 5. Successfully compiled main.cpp.example<br /> 6. Successfully compiled examples/test-session.cpp main.cpp<br /> 7. But it won't upload with <code>make install</code> even when the Maple is in continuous bootloader mode.</p> <p>Here's the output:<br /> <pre><code>@ubuntu:~/libmaple$ make installInstall target: flash ./support/scripts/reset.py &amp;&amp; sleep 1 &amp;&amp; dfu-util -a1 -d 1EAF:0003 -D build/maple.bin -R Could not find Maple serial port; defaulting to /dev/maple.

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). </p>
