Error while trying to program EPCS flash in indirect SFL mode

Hi,

On my new CoreEP4CE10 board, I'm able to upload designs successfully in FPGA Ram using JTAG, but I'm unable to program EPCS Flash using JTAG Indirect SFL mode.

Since this board doesn't have an AS connector, I have no other choice to program using SFL, so I decided to try at command-line, but I got same problem :

We can see below that SFLoader is actually succesfully loaded, but then the JTAG hang and the EPCS is not detected.

Question : Are all boards using same FPGA are compatible with those SFL "Factory default enhanced SFL image" provided ? Should I try to make my own loader using SFL Megafunctions ?

UPDATE :

Following instruction of the Troubleshooting page (http://www.altera.com/cgi-bin/ts.pl?fn=configuration&hi=2-8), I've manually uploaded the SFL into the FPGA, then I've performed an antodetect again, and I'm unable to see the EPCS, I'm only seeing the FPGA itself. Doing the same at the command-line "jtagconfig" only shows the FPGA where I presume the EPCS should also appear, but it doesn't ... I've check power supply voltages, they look fine ... Is that mean my USB Blaster is defective (but why I'm able to upload FPGA properly) ?
