[En-Nut-Discussion] SAM7256-ex interrupt

[Andreas Wickström]

Hi Harald
Sorry I have no solution for you at the moment. I tried to do the example
that I got for answer the last time but it didn’t compile so ha have not bin
able to try it out. It seems like the code for some interrupt is not linked
in when compiling the kernel but I have not investigated it so much yet.
Please tell me if you get some working code for your project.
/Andreas

Hello Andreas,
I also do have the problem, that external Interrupts (or other homemade
bare-metal-c-interrupts do not work together with ethernut correctly).
I am new in all that stuff, and do not know how linkerfiles and makefiles
have to be done to let my programs work together with ethernut.
Specially I have the problem that if I use ethernut, the ext.int. is called
on a keypress (joystick) on my AT91SAM7X-EK-board, but then it never returns
to main and system stops.

In the moment I try various makefiles and linkerfiles, as I believe it has
something to do with memory remapping (ram/rom) and organization of
ethernut, but my knowledge is too small and harald k. might have no time at
the moment to give me detailed information of how to establish an own
interrupt in ethernut.

Do you still have any solution to connect own interrupts with ethernut?
