CY7C68013A packet loss regularly
Recently, I have met a packet loss problem with the bulk asynchronous transfer from fpga to pc(16Mbps).
conf: bulk IN ; ept 6; maxpacketsize = 512; slave fifo mode.
with the data goes form 0x0000 to 0xffff as a cycle, I set the asynchronous data get length once as 512 * 256. Data loss when the data number reach 0x8800
attached are the firmware and my asynchronous transfer code.
