Hi

Thankyou all for replies

For the question

What kind of slave ports are you accessing that requires a max burst count of 128 beats

I have connected SDRAM and SRAM as slaves to DMA and tried to transfer 512 bytes at one short from SDRAM to SRAM . I have enabled bursting of 128 words in SOPC

I was able to transfer 128 bytes,256 bytes,& 384 bytes but not 512 bytes at one short

I will try out without bursting enabled & reply back with results

Regards
