10.1 EDK - When I connect with GDB to PowerPC 440 processor, I get the error, "Error: No Data on the Socket"

Description

Keywords: PPC, 440, Virtex-5, FXT, GNU, debugger

When I try to debug my software application with the debugger in XPS, I get this error message in the XMD window:

"Error: No Data on the Socket"

How can I work around this problem?

Solution

Two work arounds are available:

- Use a custom button to run GDB:
1. Project > Customize Buttons...
2. Add the line "powerpc-eabi-gdb --command=/cygdrive/c/Xilinx/10.1/EDK/data/gnu/gdb/440_cmd_file" in the data entry field
3. Press OK

- Open the GDB console and set the processor type:
1. In GDB, select View > Console
2. On the prompt, type "set processor powerpc:440"

This problem has been fixed in the latest EDK 10.1 Service Pack, available at:

The first service pack containing the fix is EDK 10.1 Service Pack 1.
