usb blaster ftd2xx.sys
Hi
Here you can refer to the answers.
Could you please describe the differences in more detail?!
What do you mean by "disconnected" - the adapter itself or the target?
--> USB-BLASTER ( with your CPLD design ) is disconnected from target board.
PC(Quartus II ) --o-- USB-BLASTER ---x--- target board
How long does it take with the one or the other adapter?
--> about 10 sec when with USB-BLASTER ( with your CPLD design)
--> less than 1 sec when with USB-BLASTER (from ALTERA )
Why do you think it is "too" long?
--> I think JTAG disconnection or reverse sided header insertion should be reported quickly when attempting downloading SOF file to FPGA.
Are you using the CPLD or the FX2 variant?
--> CPLD variant
If you're using the CPLD variant, what clock are you using?
--> 24MHz
Thanks & Best regards,
Bcarson
