Buffer handle problem
by Malathi Panyam 05 May '05

05 May '05

Hi, In my project I am using the receive.c from chapter 9. Up to now I did not get any problem. Now the receive_packet() returns the buffer handle only for the initial packets and it could not acquire the buffer handle for the remaining packets, so the packets are not able to reach the other microengines for processing. Does anybody have idea? thanx in advance, malathi

Memory allocation problem
by Malathi Panyam 29 Apr '05

29 Apr '05

Hi, I need to implement a pattern matching algo(Aho Corasick) for my project, which requires a state machine build. And since this requires memory to be allocated dynamically which is not possible with IXP1200 (no Malloc), I defined a large array in SRAM to block certain memory for building the state machine. Though I specified the start location for this array, the memory getting assigned randomly and over writing some data( a large set of rules which need to be placed only in SRAM due to alignment problems). So can anyone pl.suggest me how I can block certain amount of memory in SRAM with an array and use it for my state machine without over writing. thanx in advance malathi

Transmit Problem
by Malathi Panyam 20 Mar '05

20 Mar '05

Hi, I need to design an Intrusion detection system on IXP1200, When I tried to filter the packets based on some rules, I used the datastream (simulation) that matches with one of the rules and hence all the packets received(on port 0) should be dropped. When I debug I was able to see that the control never goes to buffer_enqueue(), and always the buffer_free() is being called, but still when I observed the log file( on port 1) I could see some packets being transmitted, How is this possible? Anybody got this kind of problem before? Pl respond. thanx, malathi

Hi, can anyone tell me that the LIFO used in allocating the buffer, when u need to transfer data frm RFIFO to SDRAM and the other one used for enqueuing and dequeing operationn are different or same... i'm using different LIFO's for the two operations....simulation is running fine for about 25000 machine cycles but after that it stops giving an error that an uninitilized data is read from sdram, or at times from sram.... not able to locate the error, has anyone of u faced the similar problem.... i have modified the code for chapter 9....transmit code is same..

Re:Simulation Problems

Hello all, I'm new to IXP1200 and am having problems simulating the program used in chapter 5 of "IXP1200 Programming".I don't have the CD containing the project but I downloaded the source files from Internet(so have to manually set project settings in SDK which is probably the problem!!).In simulation the IXP fails to receive any packets at all with the Rx buffer filling up and the receive rate gradually decreasing to 0 Mbps.Here are the project settings: Ready Bus Sequencer Program: Rxrdy Mac 0, Txrdy Mac 0, NOP1, NOP1, NOP1, NOP1, NOP1, NOP1, NOP1, NOP1, NOP1, NOP1. Data Stream: 100 frames of length 38 of Ethernet IP assigned to Device 0 Port 0. IX Device Bus Simulator is enabled. Device is set to automatically receive packets on first clock cycle. What am I doing wrong?? Regards, Simon O'Sullivan.

Re: Error: rpccore backend client Timed out (mahin jeyachandran)
by Ricardo Camarena Ramos 11 Feb '05

11 Feb '05

Hi Mahin: Ok. I don't understand very well which is your testing architecture, but if you are using the ENP2505 board you maybe have some like mine. Because I haven't heard about ENP2505 with Tornado....maybe I'm wrong. My configuration is a Linux host which runs virtually a Windows 2000 in the same machine to run the Workbench and the ENP2505 board running Linux too. All of them installed in the same computer. If that is you configuration then I assume you have already installed VMWARE and can ping bw Windows and Linux Host. This is the first thing to do. To change the IP address you simply change them on the create_environment.rc. located on the same directory where bootixp is. Although there is no need to do this change.

Timestamps in Microengine C
by tabrez rajani 07 Feb '05

07 Feb '05

Hello Everybody, Can anybody tell me how to find the packet receipt rate using microengine C.Basically I need to know if there are any time related functions (such as gettimeofday) etc that I can use in order to find the rate at which the processor is receiving packets.Also i need to record the timestamp for the latest packet from a particular IP address. Any feedback will be appreciated. Thanks, Tabrez. __________________________________ Do you Yahoo!? Yahoo! Mail - Helps protect you from nasty viruses. http://promotions.yahoo.com/new_mail

Simulation Error
by tabrez rajani 31 Jan '05

31 Jan '05

Hello Everybody, I am using the code (in MicroEngine C) for packet reception. ME-0 is used solely for receiving the packets and then enqueing them to the queue. Now I am using ME-1 for some packet processing and then it enqueues this packet again in another queue from which ME-5 reads and transmits the packets. However , in my code for ME-1 whenever I try to access any memory ,(scratch,sram or even local variables for that matter) I get a simulation error. For example I am using the function ixp_cycle_read(); If I comment this out , the simulator works.The error that I get is as follows : ***** %E-ERROR at fbox cycle 545 in simulation ---------- (NOTE: Execution will stop ASAP due to error.): Memory address, 007F8000, is out of bounds of "sdram" array. ***** %W-WARNING: Read of array, "sdram" at address: 007F8000 returns uninitialized data. Simulation prematurely stopped due to error condition. I do not understand why this shows up.I am not accessing the sdram at alll,except for enqueing the packets and dequeing them.At no point am I trying to access SDRAM memory at 007F8000. Do I have to change the build setting or something in order for me to be able to access memory even from the 2nd or 3rd microengines.Are there some memory configurations that I have to change? I'd really appreciate it if somebody can let me know what I am doing wrong. Regards, Tabrez. __________________________________ Do you Yahoo!?

Compuler Error (__mul_ not found)
by tabrez rajani 27 Jan '05

27 Jan '05

Hello Everybody, Firstly I would like to apologize for one too many questions that I have already asked.I have a deadline coming up, hence ... I have a function in which I am using the hash_48 unit.A snippet of my code is : hashInputTmp.hash_lo32 = ip_32; // This is an IP address hashInputTmp.hash_hi16 = ip_32 >> 16; // This is just a filler and the values does not really matter hashInput = hashInputTmp; However I get a compilation error for the following 3 lines of code : hash_48(&hashInput, &hashOutput, 1, ctx_swap); hashIndex = hashOutput.hash_lo32 & 0xff; tableEntry = &(hashTableIP[hashIndex]); (I have followed the same model as in Chapter 8/9) for the hash. Here if I comment out any of the above 3 lines , the compilation error goes away. The error that I get is : (0): error : Function __mul_32 not found I dont see any multiplication here , so I really cant figure out what the problem is. Looking forward to some feedback.
