Hello all!

   

I have problem to configure project AN65974 into Xilinx FPGA Spartan-6 on board USRP B210 over JTAG-connector by using iMPACT. 
iMPACT error massage is below:
"INFO:iMPACT - '1': Checking done pin....done.
'1': Programming terminated. DONE did not go high.
PROGRAM FAILED" 

   

When I use project AN84868 or AN87216, everything is fine. My bit-file is loaded into FPGA perfectly.
In my opinion, that problem is in signals FPGA_CFG_INIT_B, FPGA_CFG_DONE, FPGA_CFG_PROG_B and these signals into code of AN65974.

   

Simplified table of connections is below:
FPGA/pin                              SIGNAL                                CYUSB3014/pin
FPGA/INIT_B                       FPGA_CFG_INIT_B            CYUSB3014/GPIO[45]
FPGA/DONE                        FPGA_CFG_DONE              CYUSB3014/CTL[10]
FPGA/PROGRAM_B_2        FPGA_CFG_PROG_B         CYUSB3014/GPIO[45]

   

Is it true? Perhaps I must to do some modifications of code. What? Could you help me here?

   

Thanks in advance for any response!
Regapds, 
Evgeniy

Hi,

   

This doesn't seem to be becasue of the FX3 code. Is there any reason why do you think so? Did you do any other changes in the FPGA Configration files?

If I use AutoMaster.img from AN87216, FPGA can be configured perfectly. Is it difference between master and slave images for dowloading bitstream into FPGA?
