[avr-gcc-list] can't put static variable in specific section

[Yann GOUY]

Hi all,

as suggested by J"org, I change the list and clarify some points.

I'm using different sections to put the stacks and heaps of tasks with my 
preemptive kernel.

using labels in the linker script and canaries of sections borders, I'm able to 
check whether a task as overwritten the context of another.

my problem is I'm not able to put a variable in one of this section as long as 
it is declared as static.

does someone have an idea?

thanks by advance.

The question is why do you want to put them into specific sections in
the first place?  I remember inventing RAM sections `on the fly'
(i.e. without also modifying the linker script) never really worked,
as somehow, the linker defaulted any unknown section to ROM.

So the key would be to use a modified linker script.
