Problem booting the IXP1200 in "BootMgr" prompt
by Mohammad Shorfuzzaman 10 May '04

10 May '04

Hi all, I am facing problem booting the IXP1200 evaluation board in "BootMgr" prompt. When I power up the IXP board, following message comes in the terminal: " Press space bar to stop auto-boot... 2 " I press space bar several times within this countdown, but "BootMgr" deos not come, it goes to the default OS "cygmon". Actually, at the beginning this countdown value was 15 and that time I was able to boot the box in "BootMgr" prompt. Then I changed the countdown value to 2 and the default OS to "cygmon". But now I can't stop the auto-boot. Could any body please help me how can I get "BootMgr" prompt or how can I change countdown value (without going to "BootMgr"). Thanks, -- Shorfuzzzaman ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/

Hi Deepak, If you are just starting on ixp1200, then it is better to start with developer workbench. It is one of the best places to start testing ur ixp skills. It provides a very good environment to write, test and debug your code. Once you are done with it, then it is pretty simple to put it on the hardware(u can even do it from developer workbench - if you are using IXP12EB). --- WRT IXA SDK 2.01 --- If u are writing programs in microcode(microengine assembly lang) then u can install Dev WB on any Win OS. If u r trying something in microengine C, then u need to install it on Win NT(2k or XP will also do). ----------------------- U don't need the IXP hardware if u r running programs in simulation mode. All the best.

Hi Deepak. Hope I understand the question properly. If you are new to IXP1200 programming and doing first practices I recommend you to start on the developer's workbench. As a matter of fact you can install the developer's workbench in any computer and practice there (I mean you don't need the network processor board on your computer to run the example programs). After that you can switch to the board, but I haven't got there yet.

Reading data from sdram
by Mohammad Shorfuzzaman 05 May '04

05 May '04

Hi, I am experimenting with uC_lab1 project from the SDK. When a packet is copied from the rfifo to the sdram, I want to read that packet data from the sdram address to sdram read register. Since a single sdram address contains 64 bit data and an sdram read register is 32 bit, how can I read the whole 64 bit data to sdram registers? I tried using this intrinsic: void sdram_read(__declspec(sdram_read_reg) void *data, volatile void __declspec (sdram) * address, unsigned int count, queue_t queue, sync_t sync); I can't understand how to declare the "data" parameter as the reference says it's a structure. Please help. Thanks, -Shorfuzzaman ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/

sram shared problem with array
by Jason.Midkiff＠asu.edu 05 May '04

05 May '04

Hi, I'm an undergraduate student at Arizona State University working on implementing network address translation using the ucLab1 example code provided with the IXP1200. I'm having a problem when using the declaration as follows: __declspec (shared sram) nat_table table[15]. I understand this should enable the table to be seen by all other threads running on the same microengine. I have two threads running on this microengine. Thread 1 is responsible for lookup and modification of this table. Thread 2 only performs lookup on this table, however, it cannot see the contents of the table. This seems like it could be related to using an array since I use the shared sram keywords on other unsigned ints and it works. Any help would be appreciated on this problem. Thanks, Jason

Packet transmitting code
by Mohammad Shorfuzzaman 29 Apr '04

29 Apr '04

Hi all, Did any body try running successfully the packet transmitting code (from chap 9 IXP1200 prog. book) on hardware mode and see any packets transmitted from the ixp port? I tried to run it on IXP and it runs fine and I sent packets to the ixp port but I could not see any packet transmitted. Any help is greatly appreciated.

RE: [ixp1200] core locks using IXA SDK
by Johnson, Erik J 20 Apr '04

20 Apr '04

Hi Tim Without actually trying it, I suspect you can read from the 0xf5000000 range to issue the read lock. However, that does not guarantee the lock was obtained (see the next 12 lines of code in the same example from the book). For that you will need to poll (and update) the SRAM CSR _without any other process doing the same_. This will require mapping this CSRs physical address into the virtual address space of your application as well as finding some way of making this polling code execute in a system-wide critical section. In the end, you may find that doing this work in the kernel and providing some ioctl/syscall/whatever is easier because of these reasons. erik ~~~~~~~~~~~~~~~~~~~~~~~~ Erik J.
