Send this mail yesterday, but was not delivered
to me self, so i think this mail was lost in
space. If you got allready this mail, sorry... :-)
Hi all,
sorry, but I have a maybe stupied question again.
I want use external RAM at atmega 128
This is not the questions for setting up the
avr registers, because this is part of wellknown data
sheets. I have problems to understand
the linker scripts and header files.
What´s to do? XRAMEND is allready set in
iomega128.h.
How can I place data to external and
other variables to internal faster ram?
I´m confused by the fact that only avr5.x is
used as linker script whitout any definitions
for XRAMEND? How do this work.
I short time ago i have to change my linker
script for enabling external ram.
So I have set up a script for avr8515
with more external ram, but all
the scripts have changed for the new libc.
Must I change the new linker scripts for
doing the thing?
Is there any document to understand all this
nice stuff?
Thanks
Klaus
