Problems with Insight & ARM Angell

Problems with Insight & ARM Angell

[Andy Hare]

    I have compiled the latest Insight (07/12/99) to target the ARM
processor under NT and cygwin b20.1. The simulator runs fine without any
problems but the connect to an RDI target (ATMEL EB01 development board
running ANGEL) never returns. I get the signup messages from ANGEL but
control does not return.

    I have a copy of the ecos toolset for ARM and have added the patches
from Grant Edwards, re-compiled and this works after a fashion, it does
actually allow the code to be loaded onto the development board, but will
not step, continue does however work.

    So I know that GDB will talk to the board and run, but I would really
like to get insight working, is there anything I can do to find out where it
is failing and thus help the development effort. If anyone can point me at
the next step then I will try it and get back to you all.

Hi Andy,

Please download the latest cygwin1.dll snapshot from our site.
gdb should be able to connect properly to the board after you upgrade
your dll.

What exactly do you mean by "will not step"?

BTW, the latest gdb snapshot has Grant's patches incorporated.

At least a few of us are using it with no major problems.
Please let me know if you still have problems after the updates.
You can e-mail me directly.  Please send me the exact versions of what
compiler, gdb, cygwin dll you are using.  What you see on your screen
will also help.

Regards,
Fernando

Fernando,

    Thanks for the tip, the latest dll cured the problem with remote debug
via ANGEL. I have now not a problem with stepping through the code using
insight. I have picked up the latest diffs and will be applying them when I
get some time.
    Now the only problems I have is the code I compile not being the code I
run but this is due to a problem with not understanding the code. I am using
the EB01 from ATMEL and converting the AT91 library they issue to run under
the GCC toolset, some of the defines are not as obvious as they would seem
but I am getting closer.

    Cheers again, and if you need any testing doing I will help if I can.

Andy Hare

Yes, lots of work.  But it is worthy.

I don't have this board.  It is nice to know that you are trying to make
it run on it.

We plan to make some improvements to the rdi code and they will show up
in the snapshots (there
are a few there already - see the ChangeLog). We will post a summary of
the changes to the gdb list on sourceware, so if you find some of the
changes interesting please give it a try.

Cheers,
