Assembly succeeds with no microcode.
by Jagannathan Iyer Venkatesan 08 Apr '03

Hi, I have installed the Wine from winehq.com from the source Wine installed properly. But I am trying to do a make in my Libixprouter/ue/src. make does not complain about anything, except something in the .sed file. (Please refer log below). But there is no microcode in the microcode array as expected. For eg when I do "touch xmt.uc" and do a make, I expect the microcode in the xmt.x file but the xmt_uCodeArr[] array in xmt.x is empty. Can someone point out what is going wrong ? I can give more details. Thank you. Jagan. The output from make (collected as $make &> /tmp/make_out) after a touch xmt.uc is as follows. /* start of make - added by me */ -- preprocessing xmt -- For language 'english' several language ids were found: en_US - 0409; en_GB - 0809; en_AU - 0C09; en_CA - 1009; en_NZ - 1409; en_IE - 1809; en_ZA - 1C09; en_JM - 2009; en_ - 2409; en _BZ - 2809; en_TT - 2C09; Instead of using first in the list, suggest to define your LANG environment variable like this: LANG=en_US Assembly successful.^M -- allocating registers for xmt -- -- creating xmt.uca -- sed: file xmt.sed line 5: Invalid reference \2 on `s' command's RHS -- assembling xmt -- For language 'english' several language ids were found: en_US - 0409; en_GB - 0809; en_AU - 0C09; en_CA - 1009; en_NZ - 1409; en_IE - 1809; en_ZA - 1C09; en_JM - 2009; en_ - 2409; en _BZ - 2809; en_TT - 2C09; Instead of using first in the list, suggest to define your LANG environment variable like this: LANG=en_US Preprocessing successful; output file, "xmt.uci" written.^M ^M ^M Reading "xmt.uci": pass 1...^M Reading "xmt.uci": pass 2...^M ^M Number of uwords compiled: 0^M Number of pages compiled: 1^M Ucode output written to: "xmt.list"^M Assembly successful.^M -- extracting xmt -- perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LC_CTYPE = "", LANG = "english" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). rm xmt.sed /* end of make - added by me */

Kamesh, I'm not sure if this applies to the ENP-2305, but it did affect the IXP1200EB. Some PHY devices default 10MB mode is also loop-back mode, so on a 10MB connection, as soon as a packet is sent by the IXP1200 it gets looped back to the IXP1200, and so the process goes on, the result is a packet flood. The fix was either to connect to a 100MB device so the PHY would auto-negotiate to 100MB, or to program the PHY so that in 10MB mode it wasn't set to loopback. Rgds Mick Hi, Ping was not running. In fact the PC kind of hangs ie mouse pointer disappears etc when I connnect. I am able to see the output only after I disconnect. Configuration: Ethernet port 1 of ENP-2505 is connected back-to-back to the eth1 of the host PC ( PC in which the card is plugged in) through a crossover cable. The IP address of the IXP port is 192.168.1.150 and the IP address of the PC port is 192.168.1.3 . Also is there any option is the ixsys.config file through which I can specify the rate ?

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".

Re: [ixp1200] qstn abt debug option and l3fwdr
by Shyamal Pandya 04 Apr '03

Hi Srini, TO make DBG_MSG work you will have to modify the l3fwdr Makefile and recompile. Specifically, in the file src/microace/aces/l3forward_ace/Makefile, the assignment to the MORE_DEFS variable will have to include L3FWD_DEBUG. There is a commented MORE_DEFS assignment that includes the option. -- Shyamal Pandya Arizona State University Addr: 920 S Terrace Rd #102 Tempe AZ 85281 Phone: 1-480-966-1982 >From: Srinivasan Krishnamoorthy <sriniskm(a)yahoo.com> >Reply-To: ixp1200(a)CS.Princeton.EDU >To: ixp1200(a)CS.Princeton.EDU >Subject: [ixp1200] qstn abt debug option and l3fwdr >Date: Thu, 3 Apr 2003 01:46:17 -0800 (PST) > >Hi, > >I am using the L3Fwdr.

bug in ue driver
by Shyamal Pandya 03 Apr '03

03 Apr '03

Hi, I noticed a bug in the ue driver. In the file src/microace/comon/wbench/SA1_CoreLibs/ue/main.c, funcion ue_ioctl, the switch statement has case UENG_SETCTXSIGEVENTS within which the function uEng_setCtxWakeupEvents is called, which should be a call to uEng_setCtxSigEvents. Because of this an ioctl call with parameter UENG_SETCTXSIGEVENTS will result in writes to the CTX_*_WAKEUP_EVENTS registers instead of the signal events registers of the microengine. -- Shyamal Pandya Arizona State University Addr: 920 S Terrace Rd #102 Tempe AZ 85281 Phone: 1-480-966-1982 _________________________________________________________________ Help STOP SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=features/junkmail

Porting VERA?
by Øyvind Hvamstad 01 Apr '03

01 Apr '03

Hi, I'm currently writing a thesis that use the ENP-2505 card. In this project I would like to make use of the existing VERA software. However, I see on the list that VERA isn't compatible with the ENP-2505. My questions are: Are there any plans on porting VERA to work with the ENP-2505, and if so, how much coding will it involve? I will gladly help, but not if it takes to long. If no plans are made, please let me know, so I can rethink my work. In advance, thanks! Øyvind Hvamstad
