Hi, so how was everyone's diwali.....back to work... till now i was tring to modify example code of chapter06 and was adding the processing steps i needed...the program worked fine as per the requirement ....just the transmit part has to be included... 1..... ...now i was adding the transmit.c code of chapter09 and assign it to ME5 alonwith this but wasn't successful..... 2.... then i tried to change the receive.c of chapter09 as per my requirements (processing part was changed....instead of bridging..i have added a code to search a data structure)...but when i build the project and view the thread specific code windows, to add the break-points, seen tht tha code didn't changed as expected....after debugging the code was that of the brigding example...but when i stop debugging...i saw tht receive.c was modified as per my requirement.... 3... then i tried to create a new project...inserted the complier files , programmed the ready bus sequencer...as was programmed in the chapter06 example....but the counter which has to b incremented as packets arrived...didn't get incremented... And i'm not able to assign a data stream to a particular port...i have not included any script file....do i have to do anything else....i guess there is some problem with the MAC....or m i missing some steps.... Hope any one can surely help me out... Thanxs in advance... regards, Nitin

Problems with mod operation
by Chac 09 Nov '04

09 Nov '04

Hi: I�m implementing an RSA encription in the IXP1200 and I need to do a Modulus after division operation. I can�t find how to do this, in fact I can�t do any division because I can�t declare a variable of type fixed or float. I also have some problems to set a watch in variables when debbuging, I can�t see the values en some variables only shows an error : ERROR: invalid array range (array size = 524288) Thanks in advance, regards.

Hellow, i'm not even able to debug the chapter 8 example, its giving error regarding hash unit.......so can anyone send me the files for example code of chapter 8....debug results are as follows:::: ........................................................

Hi, I was running the chapter 8 example on develper's workbench in simulation mode. The packet with ethernet addresses 'cafebabe' and 'deadbeef' arrives in sdram correctly but when the structure headerData in datawatch shows the first word of the quadword '0000cafe' repeated over and over again . it does not show the correct ethernet addresses.Can anyone tell me what is the problem? thanks, shweta

Hi, can anyone tell me how can i restrict the sdk complier to restrict allocating variables from memory,being it any sram or sdram, certain locations or bunch of locations... i mean i need to have a basic data structure (which is a table) which store some rules...this will be iniatised at first...but need to be changed dynamically if one wants 2 add a new rule.....i want that other variables will not overwrite the content of table... so i want to restrict variables, for which i don't want to specify memory location explicitly, out of certain memory location where i have stored my rules..... i guess there is some compler settings........?????.... thanxs in advance.... regards, Nitin Makhija M.Tech(CS) IIT-Kharagpur

compiler optimizations--instruction address problem
by Shweta Rao 01 Nov '04

01 Nov '04

Hi, When i run my code in simulation debug mode on the workbench ,i have set it to display the instruction addresses and in the project settings i have set compiler options for optimization to none. Inspite of that there are two instruction where the instruction addresses does not show up and the simulator does not execute them.Is it because of the code or the project settings. The instructions are buf_handle = receive_packet(0, 5, &cur_pkt_len); //buf_data_ptr = (__declspec(sdram) long long *)(buffer_get_data_ptr(buf_handle)); buf_data_ptr = (__declspec(sdram) void *) (((unsigned int)buffer_get_data_ptr(buf_handle)) + 3); If anyone is aware of the solution,please let me know. Thanks, shweta
