Hi!
I am working with AT90CAN128 and IAR and external memory. The AT90CAN128 has some bug on "Miss-functioning when code stack is in XRAM" so I must put the heap only in internal RAM. How can I do that in IAR and what variables location I need to change?
Thanks for some help!

In GCC you can define the section that any data item goes in using an attribute ((section…)) style. Some compilers you can do the same using a #pragma. I expect you will have to setup a section in your linker for you different memory areas (probably already so) then use a pragma or attribute on the data to say which section it should go in. Can IAR do this?

Yes, I think that is possible.
Due to the AT90CAN128 problem, I have another question:
-I use queues of some hundreds bytes. These queues live in the heap.
-There is someway to get out the queses from heap and put them in the exteranl memory?
-If the AT90CAN128 don’t like to have the SP outside internal RAM that can be a problem when I move the queues to external RAM?
