You are always on time and accurately.

Could you please give me some examples on FPGA configuration using FX2..?
It is one of our application note on how to configure Spartan using FX2LP. It has been pulled down for internal review. Please let me know your mail id I'll send across a beta version of the app note.
Thank you for your help.
My e-mail address is ( firstname.lastname@example.org ) and please send me that app note.
In my design, I wanna use FX2LP to configure an Altera FPGA(GPIF func) and then to transfer data between PC and FPGA(SlaveFIFO func). Do you have examples or suggestions for FX2 uses like this?
Thank you again and sorry for I made a mistake of your name last time.
Best Regards / Lucev,
I have readand thank you very much.
My 1st question is-- how to use the same FX2 to do both parts( first func as GPIF and then SlaveFIFO )?Do I need two different FWs( init to GPIF and to SlaveFIFO ) and re-program FX2 with FW2 after configure FPGA with FW1?
My 2nd question is ,in GPIF mode, can a FPGA config status pin be connected to a FX2( 56pins )'s I/O like PA0,not its RDY pins?Because in SlaveFIFO mode,two FPGA IOs are connected to RDY0&RDY1.If the FPGA config status pin is connected to RDY,it means a FPGA IO is connected to FPGA config status pin.FPGA will probably not work correctly.
Thank you for your patience.You are really a nice engineer.
The gmail id didn't work. Sent to the other id. The configuration firmware does not use RDY pins. If you're using auto mode then slave FIFO firmware should be simple. Please look at the configuration app note as well and then update here in case of any queries.
OK,I‘ll read the app note and have a try.
Thank you for your support, Anand. Have a nice day!
You might find FPGALink useful. It is an open-source cross-platform library that:
- Loads custom firmware into the FX2LP using libfx2loader.
- JTAG-programs a Xilinx FPGA.
- Subsequently communicates with a supplied VHDL reference design using FX2LP slave FIFOs.
It supports many of the Digilent FPGA boards natively (e.g Nexys2, Nexys3, Atlys), but there's also an FX2LP reference design if you want to make your own PCB.
Can you please send me the new copy of this example file and documentation.
In previous pdf i find two problems
1. PE0 and PE5 pins are used these pins are not available in 56 pin package.
2. Its is recommended that you can use 56 pin package.
3. We need to modify the code to some other port to get this working.
Thanks and Reards
