Error while trying to program EPCS flash in indirect SFL mode

[Altera_Forum]

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 ?  Info: ******************************************************************* Info: Running Quartus II 64-Bit Programmer  Info: Version 13.0.1 Build 232 06/12/2013 Service Pack 1 SJ Web Edition  Info: Copyright (C) 1991-2013 Altera Corporation.

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) ?
