Hai chinzei,
i have some doubts.
1)-->when we send morethan 64bytes of data is split into multiple 64byte packts.
so,is it the hardware that split the packets or our device firmware needs to spit it.(i think firmware needs to split it up if so i kept my INEp and OUTEp buffers to 512 or i need to put to 64)
2)-->At an instant how much data i can read into rxfifo when host transmits 64bytes or more.
i configured txfifo[1] of 512bytes, global rxfifo of 512 bytes.
For these i also configured endpoints.
TX-EP[1] is of 512bytes and direction is IN(device to host).
RX-EP[2] is of 512bytes and direction is host to device[OUT].
i'm using bulk tranfer method
one more problem is that when i exactly transfer 64/128/192/256/320/384/448bytes from host to device ,nothing is happening.
other than these above mentioned bytes i'm reading and writing the all the data successfully including 512bytes also.
Also i enabled zero length packet.
what my requirement is to achieve transfer rate of 3 to 4Megabits/sec.
I dont know where i'm getting wrong.please solve my problem.
