Virtex-5 "Done" signal is not go high when programmed with JTAG

[penn]

Hi all,

The Done signal is not go high when I programmed the Virtex-5. 

In the process of my programming,the Done is low ,that is correct,But the LED flashes once at the program finished,then the LED is in low state.

Hi Penn,

This looks odd. All the bits in the status register are shown as 1.

Can you please reduce the cable speed and see if the error gets resolved? Do you have another cable? If yes, please try to configure the device using it.

Regards,
Krishna

[penn]

Hi,

A thousand thanks for your help.

I am a novice,Could you tell me how to reduce the cable speed?

Moreover,I config the device with three different cables,but the Done is still in low.

Regards.

Penn 

[smarell]

Hi Penn,

In the impact, go to Output-> Cable set up as shown in the attached picture.

In TCk Speed/Baud rate column, you can reduce the cable speed. 

You can refer to http://www.xilinx.com/support/documentation/sw_manuals/xilinx14_7/pim_db_commsetupdlg.htm for details on cable setup window.

Regards,

Krishna

Hi Krishna,

Thanks again.

I found some trouble about the Done signal.

I program the other simple .bit file,the Done signal is correct,but when program the .bit file of my MIG project the Done signal is wrong.

Both of the .mcs files were programmed with SPI,the program failed message be shown.

Regards.

Hi,

Looks like the device is getting programmed but the LED is not glowing as expected. is the expected functionality showing up on the board?

Do you have a PULLUP resistor  on the DONE pin? or have you enabled the "drive done" in the bitgen settings? Please check that.

[smarell]

Hi Penn,

Thanks for the update.

If you are able to configure the device using one bit file and was able to see done pin to be working as expected, then we need not suspect the hardware.

Can you please read the status register of the device after the configuration with the MIG bit file?

I suspect that the MIG bit file might have got corrupt.

Regards,
Krishna

[athandr]

Hi,

Can you also send the .bgn file for both the bitfiles? Want to make sure they have similar settings...with respect to drive done and others settings.

inHi,

Thanks a lot.

You can find my schematic in my another topic:

http://forums.xilinx.com/t5/Design-Tools-Others/Virtex-5-Programming-failed-with-SPI/td-p/478648

The both .bgn files in attachments,  the cpld.bit can be programmed succeeded,and the Done goes high.But the ddr2sdram.bit file can't.

Best Regards.

Penn

[athandr]

Hi,

The only difference i found in the bgn files is the Match cycle. For the ddr2sdram design it is given as 2 and for the cpld it is given as NoWait. I am not sure if this is a problem but just try to change it to No wait and check. Also let me know if there were any warning during generation of bitfile for the MIG design.

However can you clarify one thing here. Check the below and let me know if it is correct.

1) JTAG programming is working only for simple bit file not for the  MIG design

2) SPI programming is failing for both?

[penn]

Hi,

No warning during generation of bitfile for the MIG design. I will show it for you.

And could you tell me how to change the Match cycle?I am so sorry I can not find it.

1) JTAG programming is working only for simple bit file not for the  MIG design

Yes.

2) SPI programming is failing for both?

Yes.you are right.

Thanks.

Penn

[athandr]

Hi,

It is in the generate programming file properties. Try to regenerate the full design from synthesis to implementation and then generate the bitstream with these options. 

[athandr]

Hi Penn,

Also i checked the schematic and found that you have a 270 ohm pullup on the DONE pin externally, which i think is not sufficiente enought. The recommendation from the configuration user guide for V-5 is to have a 330 ohm pullup resistor. However to take care of that, you can give "Drive Done" as Pullup in the same "Generate programming file" properties.

[penn]

Hi,

Thank you for patient reply.

First, I do not consider that the hardware has a terrible mistake.(So sorry......). and for fear of some unknow state of the board,i change the value of PULL-UP resistance 270 into 330.But the result as before.

Besides,I change the Startup Options in Process Properties,the Done does not go high as uausl.

Regards.

Hi Penn,

Is the above status register contents read while configuring the fpga through flash? If yes, please share the contents while configuring in JTAG mode.

From the above status register, I could see that the data transmission to the fpga hasn't started.

Krishna

As you analysed,the data transmission to the fpga hasn't started, Could you give me some suggestion to correct it?

[smarell]

Hi Penn,

The .bit/.mcs file will have a sync word. The data after the sync word would the valid configuration data.

The data transmission starts to the fpga after the detection of the syncword.

Usually in JTAG mode, we expect the data transmission to happen unless there are obvious errors like- deviceid mismatch or poor SI of JTAG circuitry etc or if the bit file doesn't have a sync word (this is not a possibility if the tool has generated it).

Regards,
Krishna

[penn]

Hi Krishna,

You give me more detail explanation and I make sense about the .bit/.mcs file, according the device status,maybe the sync word is in some wrong status?

Generally,three reasons may cause this error:device id mismatch,poor SI and the last impossible situation.Now I will exlude it one by one.Because I had programmed the device  before, the second situation is not the reason. So the most probable reason is devicd id...

Aften I check the information of my project including the devide,package,speed and so on when I created the project, I find I am back to  the starting point...Aha...

Although the problem does not be solved,I may give you real gratitude.

Regards,

Penn

[penn]

Hi Krishna,

I suppose I have found the reason why the Done signal does not go high.

In image of the VCC(3.3V image1),On the moment of the device was programmed,the VCC drop up to about 1.5V.That may lead to the FPGA collapse.

But when programmig the others .bit file, this status can not appear.

Regards,

Penn
