Hi all,

when I set the new feature -m as an argument on the latest version of or1ksim like or32-elf-sim -m 8M hello, the application runs successfully. But the execution will be failed if I set the standard configuration file sim.cfg like or32-elf-sim -f sim.cfg hello to be able to turn on the GDB tool. The execution will be hanged at the of the following output listed below.

why did the application run by first case without bootloader successfully and failed by the second?

It looks like the memory section isn't getting set up right. Did you alter the sim.cfg file?

You probably want a memory section looking like (for a 32MB memory):



Those warnings don't look like they're related to memory sections, actually. How old is that sim.cfg file? And again, what changes did you make?

Hi Mohb,

Like Julius says, looks like you have an error in your config file. Could you post lines 900-950 here, so we can see what the error was.

Hi Jeremy and Julius,

I attached the configuration file I use. This file is downloaded from svn. Actually, I did not change anything in it.


Best regards,

Mohb

Hi Mohb

Oops. You've found several bugs! I seem to have introduced some problems into the code reading configuration files. Plus the sim.cfg in SVN is out of date.

1. For "section debug", the two parameters "gdb_enabled" and "server_port" are now obsolete. They are for the old proprietary JTAG interface, which is dropped. They are parsed, even though the debug section is disabled. Replace them with "rsp_enabled" and "rsp_port".

2. "section ata" is completely broken, and I don't know why. For now set the first line to be "enabled =0" and comment out all the rest.

3. The line numbers reported in the config error messages are wrong.

4. Even if you fix all this, the program hangs. The problem is the memory controller appears to be broken. Find "section mc" and change its first line to "enabled = 0".

I've filed all this in the bug tracker (Bug 1821, Bug 1822, Bug 1823 and Bug 1824 respectively).

Hopefully this is enough to get you going. We need a better parser for the config files, and we need some meaningful tests in the testsuite.

HTH

Jeremy
