I have solved the JTAG problem. The reason is that VCCINT and VCCA were not powered correctly.

I met the same problem with you: the nstatus can not go high and I can't configured the EP3C40 via JTAG neither.

So have anyone solved this problem? Maybe you can help me with your experience.

Many thanks.
