This is the Griffin guide : 2: PowerPC Code ------------------------------------------------------------------------------- The embedded PowerPC C code which interacts with LWIP needs to be modified for a specific design in order to automate the transmission of the shared BRAM. In the src/ directory are a number of main_iX_cY.c files which are example of such file. A main_iX_cY.c file is setup for a particular model with X inputs and Y channels. The main differences between the main.c files are the predefined constants: /* Globals for the udp dump server */ /* ------------------------------- */ #define NCHAN_PER_BRAM 64 #define PKTS_PER_BRAM 1 #define BRAMS_PER_PKT 4 #define NBRAMS 32 #define DESIGN_NAME I_POCO8_32CH_V002 #define DESIGN_NAME_STR "I_POCO8_32CH_V002" #define COMPILED_ON "06-Aug-2009 17:57:04" Once you have updated your main.c file for your specific design, insert the new code as main.c in the Software/ directory of the model and rerun XPS on the system.xmp file > xps -nw system.xmp > run init_bram What do you think? 2014-07-04 9:09 GMT-06:00 G Jones <[email protected]>: > I think that's the wrong place.
