Guest maexpower Posted May 11, 2012 Report Share Posted May 11, 2012 Hi Guys, I’m looking forward to design a FPGA board among others to use it as a DSP. At first I chose a Xilinx Spartan 3DSP. As this device is to slow, I decided to use a Spartan 6 LX25. The xc3sprog homepage says that the loader works for Spartan 6 using the FTDI 2232D chipset. Does anybody know, if I can use an FTDI 2232H chip instead? Is this device supported by the Papilio Loader? If so, do you think it is possible to use the chip both to program the FPGA and to communicate with my PC? Thanks Max Link to comment Share on other sites More sharing options...
Jack Gassett Posted May 17, 2012 Report Share Posted May 17, 2012 Max, I think it will not take much work to make the Papilio Loader or xc3sprog application work with the FT2232h chip. It's not something I will be doing soon but it might be as simple as adding the device ID's. Jack. Link to comment Share on other sites More sharing options...
GLion Posted October 21, 2013 Report Share Posted October 21, 2013 The FTDI 2232H is an upgraded version of the 2232D.The protocol seems the same, the big differences is in the power supply since the H version is a modern 1.8V design.I don't know about Papilio since I wrote my own loader.I am using the 2232H with a spartan 6 9K I used port B for programing and port A for a Async/Sync FiFo.Some things to note.1. When port A goes into full sync mode you can't access Port B, But port B will stay in the state it was in. I used BD4 for reset I am not sure what pins Papilio wants.2. The full sycnronous mode has a glitch on the TXE line where it will go low even if it can't receive a byte. You have to check the line at the end of the cycle to see if it accepted the byte.3. If you use a DCM or PLL lock signal to switch between Async and Sync mode you will have to leave the WR line high in Async mode and just rely on the falling edge. It seems to work fine this way.

mkarlsson Posted October 22, 2013 Report Share Posted October 22, 2013 Yes, the Papilio loader works fine with FT2232H. However, you might have to add this line04004093 6 XC6SLX25to the file devlist.txt (in the Helper_App\bin folder) since I don't think Jack added the larger device idcodes in the last build. Alternatively, you can use this (cmd-line) version of the Papilio loader which has built-in device idcodes for the larger Spartan6 devices:windows: http://www.saanlima.com/download/fpgaprog-win.zipLinux: http://www.saanlima.com/download/fpgaprog-linux.zip Also, if you use the B-port for JTAG like GLion describes above then you have to use the -d option to specify the device and port since the default behavior is to open the A port of the first found device.Read more about that in this thread:http://forum.gadgetfactory.net/index.php?/topic/1638-papilio-loader-and-multiple-ftdi-based-devices/ Link to comment Share on other sites More sharing options...
