JTAG debug support for ARM

[Friedrich Beckmann <friedrich dot beckmann at gmx dot de>]

Hi,

i have found a site http://www.ocdemon.com which offers the gnu
toolchain with support for wiggler/raven JTAG interfaces.  I have not
tested this and would like to know if anybody has some experience with
this. The sources for the Wiggler drivers are not included in the
distribution.
Is there any person related to this site? I cannot find any name on the
sites pages.
Is there something illegal behind this?

As far as I have figured it out, the standard gdb release supports the
ARM RDI interface. This requires the ANGEL software installed
(and is then connected via a serial interface).

Optionally the OLD EmbeddedICE Box which can interpret the RDI commands
to JTAG
commands can be used. The new MultiICE debug box from ARM requires
software support on the host which is not available for linux at the
moment.

There is a configure option --multi-ice in the gdb release which
lets me assume that the commercial GnuPRO tools from Redhat
have support for the MultiICE. The multi-ice-gdbserver seems not to
be under GNU license.

The JEENI JTAG interface from http://www.episupport.com seems understand
the RDI commands
directly as the ARM EmbeddedICE does. So this is also usabled via the
gdi rdi interface.

http://www.abatron.ch also offers a JTAG interface but with a dedicated
gdb driver
software for linux. gdb.

Is anybody using the wiggler with gdb for the ARM7?

Which software are you using?

Is anybody out there who is putting effort in writing a GNU-licensed
remote interface
for a low-cost JTAG interface like the wiggler?
