Configuration settings.

[Tom Barclay]

Hi,
I am currently applying XBoot to a new AVR ATXmega32A4 project.

I am having difficulty getting the code running. Specifically I am
trying to use PortE
UART. I cant find any postings on AVR freaks etc about using this port.
I am sure
it can all be made to work its just a config issue. Any help would be
appreciated.

I am quite happy to add to and extend the comments in the 'getting
started' document
based on my experiences.

I will probably (at least eventually) add some extra function to check
the existence and
quality (by CRC) of an application before jumping to it from the bootstrap.

How could I best provide the information, provided you think it may be
of use ?

I also note that you would like a GUI interface for AVRDude say. I wont
be doing that
but I will, later on, be creating a reduced functionality version to be
used in the field by a customer.
It will be Java based and use SWT as its GUI face. (I am a Java devotee
I'm afraid)

I will be quite happy to provide all the source and user documentation
top you if its felt to
be useful.

Best regards ... Tom

PS... my web site is currently down.

Hi Tom,

 

While I haven't specifically used a Port E, I have used it on several ports and it has worked just fine.  Check the errata of the particular data sheet to see if there are any silicon problems with the portE of your particular chip - I know the I2C doesn't work on PortE of the ATXMegaD4.

 

If you're still having trouble later, I can email you my working configuration.  Also, your command line output would be very helpful.  I can't stress enough how much better it is to use the Makefile included with the distribution than it is to try and program it independently - this has solved the problems of 80% of people that have had a problem.

 

I'll have to forward you to Alex Forencich, the maintainer, for your other suggestions.  I'd love to contribute to this project again, but I'm over full time on credits this term and doing a startup - no time to work on it.

 

Brad

Tom-

Well, it could be config or errata, but I think we're going to need a
bit more than "it's not working" to be of any assistance. Is it
compiling? Is it downloading? Is it simply not communicating on the
other end? How are you trying to enter the bootloader? Can we see the
changes you made to the config file?

We would be more than happy to help you and incorporate any change ideas
you have into the xboot repository. Also bear in mind that the primary
repository has been moved to github
(https://github.com/alexforencich/xboot) and the Google Code repository
is out of date.

Thanks,

Alex Forencich
