workbench debug error
by Yong Liu 29 Sep '03

29 Sep '03

Hi, everybody I tried to debug microace code on hardware using workbench. When I start debug the l3fwdr example there comes an error: "Attach to debug library operation failed" I know someone asked the same question on this mail list, but I can not find the answer. Anybody can help me? Thanks a lot! BTW, I am using enp-2505 board, embedded linux, ethernet connectiong for debug. I have set the "mode" to 1 in ixsys.config-l3fwdr. The portmapper is started. And when I debug a simple independent micro C code on the microengine, the workbench works very well in the hardware debug mode. Yong Liu

RE : [ixp1200] how to receive packets on IX Bus
by Veluchamy Dinakaran 29 Sep '03

Hi Amit, I too faced the same problem, resolved it now. U should actually program the ready bus sequencer to get the packets into the rfifo(this is basically a 12 byte program) element. U can do this in two ways(may be more), 1) write opcode into rcv_rdy_ctl reg.(see hw_init() in layer3 forwarding example) 2) choose the instructions u want to place in the register from system conf>ix bus interface. Enable bus seq. Click program and select the instructions(see uCLab1 example). and that should do... Bye, D.Veluchamy, College of Engineering,Guindy, Chennai.

Micro C Compiler
by Øyvind Hvamstad 29 Sep '03

29 Sep '03

Hi, I was planning to use microC when programming the engines, so I was wondering. 1. Has anyone been able to run uccl.exe through wine? (I can't, and vmware isn't cheap) 2. When trying to compile the Bridging example from the IXP Programming book, the file DispachLoop.h is nowhere to be found. Are there some secret library that I need? Or should I already have it? (Couldn't find it) 3. Would you recommend me to use microC instead of microcode? (Any known quirks?) 4. Would using microC involve having to port several microcode blocks? 5. Sorry for the, possibly, stupid questions. Can someone assist me? -- Øyvind Hvamstad <oyvindh(a)ifi.uio.no>

How to read data from GPRs using absolute addressing?
by Jo Ueyama 24 Sep '03

24 Sep '03

Hi All, I am writing a program in C++ to read a data from a GPR register (via uEng_readRelGpr method), which was previously placed by a microcode program (using the absolute addressing mode). The sample code to place a value in a GPR is as follows: .areg @gpr1 0 immed[@gpr1, 0xFFFFFFFF] immed_w0[@gpr1, CAFE] done#: nop ctx_arb[voluntary] br[done#] However, I can't read the value (0xFFFFCAFE) via uEng_readRelGpr (using C++ program) after running the microcode above. The resulting value (0xFFFFCAFE) seems to be swapping across different registers over the ones belonging to the same relative address with different contexts (i.e. 0, 16, 32, ...). Essentially, I'd like to place a given value to one absolute GPR register using a microcode program and read the same value via C++ program thereafter. Any idea/clue will be highly appreciated.** With Thanks, -Jo'

RE: [ixp1200] Accessing host RAM.

Yes it is possible. You will have to configure the 21555 non-transparent PCI-PCI bridge.

Hi, Is is possible to access the ram of the host from the IXP ? Is any additional configuration required to the PCI-PCI bridge ? Thanks, Venkata.

Receiving packets to ethernet ports
by Mohammad Shorfuzzaman 10 Sep '03

10 Sep '03

Hi all, I am working with IXP1200 evaluation board (B0 version) and set up the working environment following the Intel "how-to" document. The IXPEB is connected to the rest of the system through cosole+ethernet cable. What I want to do is to receive some packets to one of the 8 ethernet ports of the IXPEB and count them. I tried the Intel IXA SDK ACE model but failed as I was unable to boot the IXP box with the kernel (linux-2.3.99-pre3) that is included in the IXA SDK. Could any one please give me some directions to proceed other than the way I tried. Thanks in advance. M.

ENP2505 board as a Packet Generator
by Lim Boon Ping 05 Sep '03

05 Sep '03

Hi All, Did anyone have an idea on how to generate packet using enp-2505 board? Is it feasible to generate packet with ixp1200, or rather than using Linux OS itself (i have no idea on how to do it!)? This packet generator will be connected to another enp-2505 board, further classified into different traffic classes (UDP, TCP, ICMP etc.) and being forwarded or dropped based on their packet type. ===== Best regards, Lim Boon Ping --------------------------------------- Post-Graduate Student Multimedia University Cyberjaya, Malaysia HP: 012 3180321 "What about transforming a pencil into human brain in next 50 years?" __________________________________ Do you Yahoo!?
