Programming XC9500 (5V) CPLD

Jump to solution

Hello,

 

I posted theother day about my problem programming XC9500 (5V) CPLD's. What I am trying to do follows.

 

I need some help to figure out what I am doing wrong.

I need to program some XC5972 CPLD's. I used to be able to program them using a parallel cable. The cable will not work with my present laptop. I recently downloaded and installed ISE Webpack 14.7 on my Windows 7 computer. I also purchased a Digilent HS-2 USB programming cable. For some reason, I can not get Impact to program the CPLD using the JEDEC file.

I also read on both the Digilent website and in my IMPACT help files that the XC9500 (5V) parts are not supported by the Digilent HS-2 cable. If this is true, I need to go no further, and I will ask this question. Is the Xilinx HW-USB-II-G cable supported by the version of IMPACT supplied in ISE 14.7 for programming XC9500 (5V) parts?

Hi,

 

Yes, 14.7 should support programming of these CPLD's with the HW-USB-II-G cable.

 

The datasheet of this User guide says the same - http://www.xilinx.com/support/documentation/data_sheets/ds300.pdf

Thanks,

Hi Larry,

 

what is the error message you see?

a small number of older XC9500 devices cannot be programmed with latest iMPACT. Specifically, any devices with a silicon version of "0000" or "0001" do not support the bulk erase algorithm used by iMPACT. These devices appear as "9500_unsupported" in latest iMPACT.

 

For this we have an workaround to use 3.1isp8 or 3.3i JTAG Programmer.

Hello,

 

I think we are close to a solution. What I am trying to do is use Impact as a stand alone programmer. Here is what I am doing and the results. I probably am doing something wrong, and there is a strong probability that the Digilent cable won't work.

1. Open Impact  - Image <ImpactA1.jpg>  I selected OK to automatically connect the cable

2. Cable connected CPLD identified - Image <ImpactA2.jpg> I selected yes

3. Select the JEDEC file, this is the only file in the directory - Image <ImpactA3.jpg> Selected the file

4. Instead of getting the IMPACT processes, I get the window as shown - Image <ImpactA4.jpg> SInce I didn't know what to do, I selected OK. Note: in the drop down menu "Operations" The only entry is "Access FUSE Registers"

5. Right click on the device and I get  - Image <ImpactA4.jpg> Clicking on "Set Programming Properties" sends me back to - Image <ImpactA3.jpg>, This seems to be a never ending loop. I can not perform any operations. Closed Impact

6. Tried to re-open IMPACT iget  - Image <ImpactA5.jpg>

 

I need some help to find out what I am doing wrong.

Purchased the USB Platform Cable, installed it and programmed the part - no problem.  Success!

 

Thanks
