Reprogram the CPLD of USPR2

Dear all,

USRP2 FPGA can be reprogrammed and u2_rev3.bin will be generated and
wrote to the SD card.

How about reprogramming the CPLD? Any advice on programming CPLD?

Please help.

Thanks

Dear Matt,

Thanks a lot for your reply.

I have Xilinx 10.1 installed (ISE, chipscope…).

I also have a Xilinx USB platform cable 2 which is connected to both
USRP2 and my PC.

So can you help to identify the programming process:

  1. I modify boot_cpld.v and implement it with Xilinx

  2. I configure USPR2 CPLD through the USB platform cable 2 with the
    newly generated files.

My question is:

  1. which file I need to use to reprogram the CPLD?

boot_cpld.jed or boot__cpld.bin?

  1. Which tool I need to use to download the file to program the CPLD?
    Xilinx Chipscope?
    A little bit detailed explanation will be extremely help!

Thanks a lot!

Regards,

You will need a JTAG programmer. J203 fits the Xilinx platform cable,
but you can connect directly to the pins if you need. See the USRP2
Configuration page of the schematics.

The .jed file is what is programmed into the device. I think the .msk
file is important to have as well.

No, you use Impact.
