no free buffers for rx

Hello there,

I have make FIFO to its maximum value and that is 65536 x 32 Bits (Attached Print screen of TSE FIFO). And On chip memory is 65535 x 32. I don’t have any idea what become the descriptor memory size?

i have made following changes in ipport.h

#define NUMBIGBUFS 512

#define NUMLILBUFS 1

/* some maximum packet buffer numbers */

#define MAXBIGPKTS 512

#define MAXLILPKTS 1

#define MAXPACKETS (MAXLILPKTS+MAXBIGPKTS)

#define BIGBUFSIZE 512*200

#define LILBUFSIZE 1//128

Which satisified the equation

NUMBIGBUFS*BIGBUFSIZE+LILBUFSIZE*NUMLILBUFS = Size is equal oa less then packet memory that mean

That is

512*512*200+1*1 = 52,428,800

Or 52,428,800/1024 = 51,200 <65535 (packet mmory)

and still i got the same error saying "panic: out of mem"

regards
