Hi All ,

I am trying to perform debugging the openrisc systems on the FPGA. I used this link, http://www.rte.se/blog/blogg-modesty-corex/debugging-openrisc-1200/2.13 as a reference.
I managed to connect the proxy and jtag tap controller, connecting gdb to target and compiling the c program. However, as I wanted to load the program, I got the following message:

This GDB was configured as "--host=i686-pc-linux-gnu --target=or32-elf".
For bug reporting instructions, please see:
." target="_blank">http://bugzilla.opencores.org/>.
(gdb) target remote localhost:55555
Remote debugging using localhost:55555
0x00000104 in ?? ()
(gdb) file uart.elf
A program is being debugged already.
Are you sure you want to change the file? (y or n) y
Reading symbols from /home/hafez/sw/ormcu_driver/driver/DINI/uart.elf...done.
(gdb) load
Loading section .vectors, size 0x2000 lma 0x0
Load failed
(gdb)

Is there any suggestion to solve this issue.

Thanks and Regards,
Hafez

Hi Hafez

Could you try using the command "set debug remote 1" before the "load" command and then report the output you get from the "load" command. It looks like the proxy is failing to write the image to the target, and this may give some indication of why.

Best wishes,

Jeremy

Hi Jeremy,

Attached is the output of the load command. How do I know whether the problem is caused by the proxy or jtag connection or other things? I managed to connect the jtag debugger to the board by using the command : ./or_debug_proxy -r 55555

Thanks and Regards,

I have the same problem when loading the program.Does anyone have any idea about this?
