[UrJTAG-dev] Support for XCR3256XL

[m***@gmail.com]

Hi,

I recently bought Xilinx CPLD from ebay which is XCR3256XL in QFP144
package 3.3V but when I connect it to JTAG, it reports Philips brand, and
unknown part.

It seems these are very old CPLDs

They still can be programmed with ISE 8.1 or 10.1

I would like to use Bus Blaster v4 from Dangerous Prototypes to program it
with urjtag.
What would I need to add support for these type of device to urjtag ?
Is that feasible ? I just want to make use of the chips I acquired.

Thanks,
Mateusz
