Fail to program an FLASH after the eFUSE of the FPGA was programmed.

[yuwangbj]

Hi, there,

I made a design with XC6S75. Now I am going to usethe  AES encrypting the code.

Doing following steps, the FLASH couldn't be programed:

1)  Ticked the check box in Encrypt Bitsteam option.

2) Select eFUSE to store the AES key

3 ) Enter 64 charachters hexdecimal value

4) Specifies the nameof the input encryption file (.nky)

5) Leave the AES initial vector to be blank

6) Generate BitStream file (.bit)

5) Generate the PROM file (.MSC)

8) Using iMPACT and USB Cable, program the eFUSE with the .nky file generated before

9) Program the FLASH with the MCS file generated before.

10)iMPACT prompted that the program process failed.

after this, repeated above steps, program failed again. But the non-encrypted bitstream still works on the board.

BTW, The ISE version was Webpack 14.7, the Cable was USB platform.(not USB-II platform).

Anybody can help?

Thanks,

Wang

Hi,

The EFUSE register is one time programmable.

When you are trying to program the flash from the FPGA using indirect programming, .COR file is programmed into the FPGA. Since you already have the EFUSE registers programmed on the fpga, it will accept only the encrypted bitstream. Probably that is the reason you are not able to program the FLASH.

Please paste the error that you are getting while trying to program the FLASH.

> it will accept only the encrypted bitstream. 

This is incorrect.  There is an option to enable AES only encrypted bitstreams, but this is not the default and the OP specifically stated that they were able to program the device with an unencrypted bitstream so the bit has not been set.

> 10)iMPACT prompted that the program process failed.

Please post the log file that shows the failure.  Be very careful to not disclose the 64-bit AES key when you post this.

Sorry replying so late, I was on a trip. Just tried to program the flash again, and it prompted "Program Faild" as before. the log file attached bellow:

The log file shows that the issue is with the PROM programming the FPGA and not with the programming the PROM. 

• What happens if you power cycle the board?  Does the device correctly configure? 
• Can you use the encrypted bitstream to configure the device through JTAG?
• What happens if you program the PROM with a non-encrypted bitstream?

[yuwangbj]

Before programmed the eFUSE with the key,  non-encrypted bitstream could be download to the board in both JTAGE or PROM ways. The board worked well.

After the programmed the eFUSE, encrypted bitsteam can not be download to the PROM.

Also, the encrypted bitstream can not configure the device with JATG.

But with non-encrypted bitstream, the device can still be configured with JATG, and the PROM can still be programmed.

Hi,

Please read the EFUSE registers from IMPACT and paste here. Especially the output of the FUSE_CNTL control register.

Also send the ""Read Device Status" output which should help identify which stage the configuration failed.

Hi, athandr, 

Sorry replying late. I was using USB cable and it doesn't support to read eFuse. Had just bought an USB II Cable.
