    Q: I'm wondering about the 'update' command in LoLo.

    1. What is it capable of updating?

    2. Can the xc2c64a FPGA on the board be updated with it?

    We have a .upd file, and when I point the update command at it it looks like is running an Altera FPGA programming utility.

    3. What is in the .upd file, and how is one created?


    1. The update file is used to update the CPLD

    2. Yes

    3. I will have to look into whether we have any publicly available instructions on creating the CPLD.

    Thanks for the response. The xc2c64a is a Xilinx part, so when LoLo's 'update' ran the Altera FPGA/CPLD "jam" programming utility it surprised me. Xilinx parts typically use SVF, XVSF, or STAPL files -- is the .upd file one of those, or a variant? Is the reason that the CPLD is programmable so that LogicPD can send out new releases for it, or is it something that LogicPD expects that a user might want to program? Is the board typically shipped with the CPLD programmed? Does the CPLD do anything more than interface to the compact flash?

    Thanks, Dave
