[En-Nut-Discussion] Status of CAN128 Port?

[Henrik Maier]

Hello Marc,

all my current porting work has been committed to the CVS.

In regards to the status of the AT90CAN128 port, please refer to my
earlier post from "Re: [En-Nut-Discussion] Forward of moderated message:
AT90CAN128" from 2/4/05. As mentioned in this post I experienced issues
relating to stack operations in XRAM while interrupts are enabled.

So far I have not been able to solve this issue or to find a work
around. The issue is completely unrelated to Nut/OS, however Nut/OS
context switching model will place the SP eventually in XRAM and then
crash on a AT90CAN128.

I wrote a little test program which demonstrates the issue and posted it
in the AVRfreaks forum hoping that someone else can either confirm or 
disclaim the findings. Had no answer yet, neither positive or negative.
Refer to the following link:

I would be very much interested to know how your AT90CAN128 hardware
will perform.

Cheers,

Henrik
