Topic: Backing up Current Firmware

Hi all,

Just a quick question: do any of you know if it's possible to backup the firmware currently installed on the printer?
In another forum, it was mentioned that one possible way would be via JTag (If certain bits weren't locked)

Just checking here in case someone has any ideas.

Thanks!

if it isn't broken, you haven't modded it enough

Re: Backing up Current Firmware

Just curious what your goal is?  What are you trying to actually backup?  The firmware is downloadable.  The SN itself can also be reset....I just don't personally know how.  The people over at Voltivo do though.

Re: Backing up Current Firmware

I'm keeping a repository of all previous versions of XYZ firmware and software.

I just wanted to add it to my collection.

Also, sometimes, by analyzing previous versions, insights/backdoors can be found into newer versions.

Re: Backing up Current Firmware

I backed up my Solidoodle firmware using my ISP programmer to read the existing contents before I changed it (important for solidoodle since there is no other way to get the original firmware :-). It depends on the way the "fuse" bits are set though. They can be used to disable reading the firmware once it is written.

Re: Backing up Current Firmware

Claghorn - could you give some more details on how you backed it up?
What device did you use?
Thanks

Here's the stuff I wrote up on my solidoodle firmware experiences:

A few paragraphs from the top I talk about backing up existing firmware. I think any ISP with support in avrdude would work the same way if you just change the -c option appropriately.
