Programming a MaxII and have an error 44

Hi

I'm trying to program my CPLD, but when I plug the USB blaster and start the tool Programmer, I have the error 44. What can I do with that?

Maybe I've made some mistake with the VCCint and VCCIO pins. On my proto all the VCC are linked, is this a mistake? I've done this because I power the CPLD in 3.3V and my outs are in 3.3 too.

I've seen that all the VCC pins must be connected.

I don't remember if TCK TMS need a pull up or down resistor, maybe it is my mistake.

Thanks for helping

    I've forgotten to put ground and VCC of the JTAG but it did not work anyway.

    Error: Unexpected error in JTAG server -- error code 44

    Error: Operation failed

    hi,

    i have an EPM570GT100C5N MAX II CPLD and get exactly the same errors on Quartus II 9.0, 9.1 and 11.0.

    Could you solve the problem meanwhile, please?

    Cheers

    Have you solved this problem?

    I'm getting the same error with MAX V, 5M570ZT100C4N , My VCCIO and JTAG at 3.3V

    Anything?
