There is a wealth of material to support both SystemC and JTAG on the Internet.

The Open SystemC Initiative (OSCI) provides an open source reference implementation of the SystemC library, which includes tutorial material in its documentation directory. These may be accessed from the OSCI website (www.systemc.org).

OSCI also provide a number of public mailing lists. The help forum and the community forum are of particular relevance. Subscription is through the OSCI website (see above).

The main GDB website is at sourceware.org/gdb/. It is supplemented by the less formal GDB Wiki at sourceware.org/gdb/wiki/.

The GDB developer community communicate through the GDB mailing lists and using IRC chat. These are always good places to find solutions to problems.

The main mailing list for discussion is gdb@sourceware.org, although for detailed understanding, the patches mailing list, gdb-patches@sourceware.org is useful. See the main GDB website for details of subscribing to these mailing lists.

IRC is on channel #gdb on irc.freenode.net.
