ENP2505 Example Issues
by Cyrus Hall 21 Apr '03

21 Apr '03

I recently started working with the ENP2505 board that Intel is shipping for their IXP1200 academic program. After hacking their install scripts, dealing with kernel symbol issues, and hacking their boot scripts, I finally got the thing to boot Linux and communicate with the host system. I then made the encouraging discovery that all the sample projects are (seemingly) for other boards. Although they'll load, the board will proceed to spit out malformed Ethernet packets (each packet identical) as fast as the interface will allow. This is with the simple packet counting example. Is there a bare bones MicroACE, such as the counting example, that actually works on the ENP2505? Also, the documentation and tools provided with the board seems to indicate that using the ACE development paradigm is mandatory. Is it possible just to run microcode with no communication back to the ARM on ENP2505, ie, non-ACE code? Thanks for any pointers, Cyrus Hall hallcp(a)cs.colorado.edu University of Colorado Software Engineering Research Laboratory

RE: [ixp1200] How to generate asm code from SDK
by Heaton, Eric D 04 Apr '03

04 Apr '03

Yan, This warning should have no effect on the production of an .asm file. Of course, if you had errors in your build, that is a different story. Check your build directory for a file named <c_file_with_main_in_it>.asm if you didn't specify a specific name with the -Fa switch. But note that you can look at the assembly code generated from a Microengine C file easily without using the -Fa switch. When using the Workbench (v2.01) in debug mode, choosing a thread to view will, by default, display the source code for the thread. However, there is a toggle switch on that window (it has a yellow and green page icon circularly pointing to each other) that will display the .list file containing the assembly for the source code line your cursor is currently on. Check it out! --eric h. -----Original Message----- From: Yan Luo [mailto:yluo@cs.ucr.edu] Sent: Sunday, January 12, 2003 12:02 PM To: ixp1200(a)CS.Princeton.EDU Subject: [ixp1200] How to generate asm code from SDK HI, I try to generate the assembly code from Micro C code using SDK 2.0, In the Build->setting, I check the "Produce assembly code file". When I compile , I got the following warning: (0): warning : IPO enabled; -Fa and -FA produce dummy .asm files It seems it did not produce asm file, and I cannot find asm file anywhere. How can I get the assembly code? Thanks, Yan

route_add() problem
by Li Zhao 31 Mar '03

31 Mar '03

Hi, I want to put a large routing table to the L3fwd16 project in the IXP 1200 simulator. I changed the size of the sram and some parameters in mem_map.h. But it seems that the functions route_add() and ht_add() donot read the mem_map.h file at all. The route_add() gave some error message after reading about 200 routes. Then the IXP 1200 simulator crashed. Since these two functions are from the dll library, the implementation is unknown to me. Are they compiled with the fixed SRAM size and sram_route_base parameter? If so, is there anyway I can do to insert the large routing table? Thanks a lot! -- Li Zhao Dept. of Computer Science Univ. of California, Riverside Tel:1-909-787-2001

SA interrupt
by Shyamal Pandya 23 Mar '03

23 Mar '03

Hi, I want to deliver an interrupt from the microengines to the Strong core processor of the IXP1200. The core runs Linux. After reading through the source code of the microengine driver, I figure that each time the microengines are initialized, the ue driver registers an interrupt handler with the linux kernel for a microengine interrupt. There is also a function uEng_intConnect, that can be used to register a handler function with this driver. (For example the debug library uses the function to register some function). But this function is not exported to the outside world. If it were, then one would do something like write a module stacked on the ue module and use the uEng_intConnect function to register its own handler function. I cannot avoid not using the ue driver because I am using the MicroACE framework. What can be done so that somehow I can catch a microengine interrupt on the core processor? I don't know if I have been quite clear, but I will appreciate any help.

RE: [ixp1200] SA interrupt
by Arthur Berkovitch 23 Mar '03

Hi, I do exactly as you described with uEng_intConnect, but with VxWorks and without MicroACE. It works fine! I looked at the ixasdk2.0 /opt/ixasdk/src/microace/commom/wbench/Inlude/ueng.h and found there the declaration for uEng_intConnect. Please let me know about your progress because. I consider moving to MicroACE and Linux and the SA (or XScale) to ME communication is an issue in our application. -----Original Message----- From: Shyamal Pandya [mailto:shyamalpandya@hotmail.com] Sent: Sunday, March 23, 2003 6:52 AM To: ixp1200(a)CS.Princeton.EDU Subject: [ixp1200] SA interrupt Hi, I want to deliver an interrupt from the microengines to the Strong core processor of the IXP1200.

EN2505 card causes PC to hang.
by Kameswara Avasarala 20 Mar '03

20 Mar '03

Hi, I have plugged in an EN-2505 evaluation board into a PII PC running RedHat 7.3 . I was expecting to see the 2155 PCI-PCI bridge listed in the ouput of the lspci command. However, it was not detected. The same card when plugged in a PIII with RedHat 7.2 casued the PC to hang ie it did not boot. What are the reasons for the above behaviour ? 1) There is no software/OS running on the board (except for the System Moniter). The switch SW1301 is set as 001 (System Moniter) . 2) The switch SW0201's bit 1 is on for Slave mode operation and the bus width not 64 bits. All the other bits are default values. Thanks, Kamesh.

microC compile problem
by Maruti G Gupta 19 Mar '03

19 Mar '03

Hi, We are trying to write a program in microC using the IXP developer's workbench. In the process we used some intrinsic functions from the library provided called ua_get_u8() and ua_get_u16() and included the header file ixp.h. However, we get a compiler error saying function __shr_64 not found . The function does not seem to exist anywhere in the include/ or even in the files and subfolders under the IXP1200/ directory and we haven't yet found a file containing an implementation of it either. Please, does anyone have a fix for this problem ? thanks, Maruti

port #3 in half duplex mode
by Najati Imam 12 Mar '03

12 Mar '03

Is there any reason port #3 on my ixp1200 is only running in half duplex mode? Is there some system setting that tells the ports what mode to run in. Its not the wires or the switch the 1200 is attached to, so I've deduced that its he boards fault. Najati
