Signal 'ET_ILLEGAL_RESOURCE' received??

Postby muntablues » Tue Nov 26, 2013 8:46 am

Hi there

The first boards (http://www.xcore.com/forum/viewtopic.php?f=21&t=2355) have arrived and look good.

I tested all voltages and they look good and stable.

I started the first SW test, but there is something wrong!
I use reference design SW package (6.10) but if I start degubbing I get

stdcore[0] core[0] (Suspended: Signal 'ET_ILLEGAL_RESOURCE' received. Description: Resource exception.)
1 main() 0x00014470

That is all I get, I can't see where is something wrong and its really hard to find a error. I didn't change any code and so it is quite strange wor me. I think it should work fine on my custom design...

I anyone could give me a hint it would be really great!

Thanks MB

The first thing I'd do to debug that is to run:

Code: Select all

xgdb <YOUR_BINARY> -ex "attach"
If you've got multiple XTAGs then use:

Code: Select all

xgdb <YOUR_BINARY> -ex "attach --adapter-id <ID>"
Then the following to give you a list of all the active logical cores:

Code: Select all

info threads
Find the one which is in _DoException() and switch to it by doing:

Code: Select all

thread <NUMBER>
Get the status of the thread using:

Code: Select all

info reg
That will show you the Saved Program Counter (spc) which is the Program Counter of the instruction that caused the exception. It also tells you which function that is in. The output will also give you the Exception Data (ed) which in the case of an ILLEGAL_RESOURCE is the resource ID of the resource being accessed by the instruction at spc which caused the exception.

The disassembly of the function in which the exception was and the info reg output would both be helpful in debugging the issue. The disassembly can be obtained by:

Code: Select all

  disass <FUNCTION_NAME>
That's about all I can say without more information.

Hi peter

Here is what i get:

The program being debugged was signaled while in a function called from GDB.
GDB remains in the frame where the signal was received.
To change this behavior use "set unwindonsignal on"
Evaluation of the expression containing the function (_DoException) will be aban
doned.

Note: If I reset the device, all these commands does not work. It works only if I start debugging in TIMEcomposer, stop debugging. After that I get upper results. I am not sure if that is correct?!

That is a start, but there isn't enough information there. First of all, the address at which the exception occurred is:

Code: Select all

spc            0x14470  83056
So, you need the disassembly of the function that this PC is in. "info threads" has told you that the core is in _DoException(), but that is the exception handler. You can try to get the backtrace to see whether that gives you more information about the call stack at the time of the exception:

Code: Select all

bt
But that isn't always too informative. In order to understand what instruction is causing the exception then you can use the following command-line tool (open the command-prompt and change to your project folder):

Code: Select all

xobjdump -D YOUR_BINARY  > objdump.txt
You can then open the objdump.txt file in an editor and find which function PC 0x14470 is in and what instruction it was executing at the time.

From the Exception Data (ed) value of 0x2 it is a channel operation. Resource Identifiers are 32-bit values of which bits [3:0] are the resource type and [15:8] are the resource number. The bits [31:16] identify the tile on which the resource is located.

Usually when an exception occurs on a channel then it is a protocol violation on that channel. Channels can carry both data tokens and control tokens. If a control token is sent and the other end of the channel expects a data token then an exception (ILLEGAL_RESOURCE) will occur.

So, have a look at the code that is executing at the time of the exception and see whether that helps.

Thank you very much!

I have created the dump file and here is the relevant part. For me it is very hard to understand what is going on, but maybe you can find mistake.

As I mentioned in the first post. It is the orig. source code from 6.10 package and my HW is more or less the same as XMOS USB Audio 2.0 DJ Kit!

Code: Select all

(FWIW, "disas main" or "disas 0x14470" should work within GDB).

Curious. The code is trying to free channel end #0, which is
not already free it seems; which then means there is pending
data on it, or some other thread is using it?

Something went really badly wrong :-)

I tried disass command (main shows only 250 rows) so I use start end now. Maybe someone can find the problem...

So it is trapping in the main when freeing a channel:

Code: Select all

             0x00014470: e1 17:       freer (1r)      res[r1]
This is usually caused by boot mode selection issues. Can you confirm that when you reset the board, and then run:

Code: Select all

xgdb -ex "connect" -ex "info threads"
You get the PCs at the right location. Something like this:

Code: Select all

0xffffc070 in ?? ()
  2  tile[1] core[0]  0xffffc070 in ?? ()
* 1  tile[0] core[0]  0xffffc070 in ?? ()

Does your binary still run on the DJ Kit (XP-SKC-SU1)? If not, then could you send the binary and I can try to debug it on my SU1.
