I have the revB development kit. The kit was working fine for a really long time until it suddenly stopped being recognised by the Quartus programmer. The USB blasterII is recognised under my device manager (I'm using windos 10) and seems to be fine. However, there seems to be a problem with my JTAG chain. How should I solve this problem?
If you are using JTAG header check if we have connected it in proper orientation.
If you are using embedded blaster Ensure all power supplies to the device are within recommended operating conditions. Refer to the respective device handbook for the correct voltage level.
Ok, I finally managed to borrow my friend's terasic USB blaster cable (They're expensive and I'm a student) and it seems to work fine on the first try. The USB blaster then turns off and the FPGA board needs to be turned off and on to make it work.
This leads me to believe that the embedded USB blaster chip was indeed damaged somehow (not sure how or why) and there is now a separate issue with the external USB blaster which causes it to turn off after the first try.
Good to know that board works with jtag header.
