Programming a CPLD

Post by neptune »

Odd question but can I use this to program another Xilinx CPLD? I do not need the USBJtag NT to EMULATE a Xilinx chip I just need it to be able to program one.

Is this possible?

And Who Said the USBJTAG NT is Emulating an Xilinx chip?

0.54 now support Xilinx programming. Read other thread and watch youtube

I need to program the same cpld that usbbdm used in the other thread but am confused on one point.
At one point you indicated the usbjtag nt hardware would need to be sent back for an upgrade, is this the case and if so how do we arrange to do that.

I'm sure you are about to be overrun with CPLD and NAND dumping questions as the reset glitch hack just got dash launch support :-)

Thank you again,

Brian

For new shipment there is no need to send back. Only older ones need to upgrade. The ones starts to support this is hardware ID 4391 and up.

How would I go about exchanging my pre 4000 NT?

I'm in the UK.

Cheers.

generate stapl (JAM) file from jed file

Post by nahdude »

The RGH release comes with jed files, but usbjtagnt uses stapl files. Here's a quick video to show how to generate a JAM file from a jed file with iMPACT.

I am not sure if the converted file from JED will work. I had someone created Stapl file from the compiler and that works fine. I tried once with the converted file and that did not work. You can have a try and report back the result.

Works perfectly with RGH v1.1 tested on a falcon MB.
It runs surprisingly fast and consistant.
It never takes more than a couple seconds to boot into custom dash/xell!

I noticed when programming the cpld that the software returned something like..

EXPORT key = BUFFER_YADA_YADA, value = 1185

I don't remember what it exactly returned, but there was 0 crc errors and the file executed successfully.

I also tried generating the stapl file with the source files in Project Navigator. This also works. The only difference that I can tell is the time stamp and ISE software versions of the resulting file.

Thanks again for all the outstanding support.

Did you manage to patch the NAND with the ECC file and flash it with the NT?

I'm having trouble with this.

Do you mean Hardware Id or Serial Number to tell if we need hard ware upgrade?

thanks

Hardware ID and serial number are the same thing for JTAG NT.
