Title: How vendor specific request/cmd on EP0 processed by FT601?
Post by: bhoomil on June 08, 2018, 05:15:08 AM

Hi,
I have a requirement like,
Send FPGA specific cmd (i.e. set/get register, download firmware etc. ) to send from host to FPGA via FT601. I found that FT_ControlTransfer() API can do this thing by setting up the tSetupPacket field. But I have one query, How such vendor-specific request handle by FT601 core. Does EP0 data comes out to slave FIFO and send it to the master FIFO of FPGA just like in case of IN/OUT EP?

Hi,
Sorry, but there is no information about default endpoint.
The ch-1 is only contained discussion about 0x01,0x02,0x03,0x04,0x05 BULK OUT endpoints and 0x81,0x82,0x83,0x84,0x85 BULK IN endpoints. Not finding details about 0x00 default/control endpoint in the entire D3XX programmer manual.
