nStatus unconnected on cyc1

Hi, I have a design which the nStatus pin is not connected to pull up. This situation is probably the reason that i cant configure the FPGA in AS mode. But, when can configure the FPG...

Well,

I understand that even, by chance, it is working - you are suggesting not to work with this kind of configuration (nstatus is not connected).

In addition, JTAG-only is a configuration scheme of rather limited purpose. For this reason, you won't find much users, that have tried the same.

Jtag can perform FPGA programming and if it will be used for this purpose only (program FPGA via jtag each power up by a proccesor), I think it will be OK. Don't you ?

(ALTERA also gave the source code and documantation for programming FPGA using JTAG and its called "jrunner")

Maybe to program the FPGA with PS is better ? (but no SW to support in PS programming)

thanks,
