CPLD: Altera EPM3128ATC100-10
Software: MAX+plusII 10.2
Language: VHDL
License: full
OS: Windows 98/2000
Download type: Altera ByteBlaster MV
Download chip: 74HC244
In my project, I want download the *.pof file to my CPLD. But a warning message always jumps out: "Unrecognized device or socket is empty". I have checked my board, but there is nothing wrong.
In my board, I used 2 types power:3.3V for core, and 5V for IO port and there is no clock to drive the CPLD (This CPLD is designed as a substitute for a programmable buffered I/O expander, so there is no clock in it).
I think there must be somrthing wrong that I have not found, so please help me what possibility can make this error?
Thank you!
