Remote GDB to JTAG

Remote GDB to JTAG

[alfred steele]

Hi
 I am trying to debug u-boot using arm-elf-gdb. I have been
succesfully using this gdb to a great extent. However, when i try my
vanilla u-boot image with debug, i get a "segfault". Could it be
something wrong with the binary itslef. If so, any hints as to what
could be wrong?

(gdb) symbol-file u-boot
Load new symbol table from "u-boot"? (y or n) y
Reading symbols from u-boot...done.
(gdb) target remote 206.44.17.238:2001
Remote debugging using 206.44.17.238:2001
Segmentation fault

Thanks,
ALfred.

Hi

I am using arm-elf-gdb version GNU gdb 5.3 .

I am trying to debug u-boot using arm-elf-gdb. I have been
succesfully using this gdb to a great extent. However, when i try my
vanilla u-boot image with debug, i get a "segfault".

This is an ancient version of GDB now.  Please try a current release.
