Hi all!

How can I debug C/C++ program on de0-nano board?

I am new but studying OpenRISC and OrpSoC.

I am trying to run and debug simple C/C++ program on de0-nano board.

I have downloaded OrpSoC ver orconf2013 on de0-nano board.

Compile of test program by GCC ver 4.5.1 was ok.

To debug my program I connected JTAG and started debug proxy and gdb to load program.

But, whenever I try to connect de0-nano board by or32-elf-gdb, internal-error: get_frame_id happens. (When I

connect de0-nano board by or1k-elf-gdb, internal error does not happens)

Also, whenever I set a breakpoint in the program it does not stop at breakpoint.

Please tell me how can I debug orpsoc.

I am using or32-elf-gdb: GNU gdb (OpenRISC 32-bit toolchain for or32-elf (built 20110410)) 7.2-or32-1.0rc3

and or1k-elf-gdb : GNU gdb (GDB) 7.6.50.20130930-cvs

Thanks in advance.
