hi,
Does Xilinx not provide another interface to download configuration into CPLD? For example, Altera ACEX1K provides some ways: JTAG, serial shift and parallel loading. JTAG is complex interface/protocol and in most cases it is not necessary no utilize it without good reason. My current project uses SiLabs C8051F120 connected to ACEX1K50 via serial downloading and does simple bit-by-bit transfer of configuration file generated with Altera software. Look at Xilinx datasheet for alternative configuration. Regards, Oleg We've been using the Xilinx 'Parallel Cable IV' to program the CPLD during assembly, and it works fine. But once the unit is closed up, it is extremely difficult to open back up to access the programming connector. We need to be able to make field revisions to the CPLD via the serial port on the uP. |
