Hi,
I have successfully run the OPRSOC platform with the help of Opencore Organization.

My question is how to dump the memory from GDB.
I use the command :
% dump binary memory mydump.bin 0x100 0x1000

But the result is :
% Cannot access memory at address 0x100

Why?? Actually i can run the program from 0x100. Pls help me. Thx a lot!

Hi dinsh

Could you post the full trace of your gdb session, and the program you were debugging at the time.

Thanks

Jeremy

hi,I also have the problem. why can not access memory?

Hi drmicrotiger

Please post a trace of your session. For example if you are debugging a program called "myprog", run GDB as follows to capture a trace in /tmp/log, and then attach /tmp/log to a message here.

or32-elf-gdb myprog 2>1 | tee /tmp/log

I'll take a look and see if I can understand why you have a problem.

Best wishes,

Jeremy

Can you even examine (read) memory with the following?

gdb> x 0x100

Hi,
This problem/bug is only occurring when using the "or_debug_proxy". Using OpenOCD works fine, but installing OpenOCD on Ubuntu 12.04 was not accordingly to the installation guide (needed modifications).
