I'm trying to debug a custom board with a LS1046A processor with gdb. For this I have connected the CodeWarrior TAP to the board via JTAG and to my PC using Ethernet. Using this setup I can successfully connect to the TAP via telnet. The TX/RX LED on the TAP is blinking green and the RUN/PAUSE LED is red.
When I try to connect to the gdbproxy on the TAP from my host machine I get 'Connection timed out' message from gdb. According to this thread the problem could be that the gdbproxy is not running on the TAP. Unfortunately I can't really follow the instructions Sinan Akman wrote down. Could you give me a more comprehensible guide on how to start the gdbproxy on the TAP?
Additionally, according to this thread a special target.xml file is needed. Where can this file be found for the LS1046A processor?
