But, I'm not able to program the EPCS with my cheap Blaster, the SFL macro seems to be loaded properly on the FPGA according to jtagconfig -n, but then, the quartus_pgm is unable to communicate with the SFL and see the EPCS : Info: ************************************************** ***************** Info: Running Quartus II 64-Bit Programmer Info: Version 13.0.1 Build 232 Service Pack 1 SJ Web Edition Info: Copyright (C) 1991-2013 Altera Corporation. Recently, I've purchased a Cyclone IV board which has only a JTAG, so the EPCS flash on it can only be programmed using JTAG indirect using SFL.

Hi everyone ! I have a cheap USB Blaster $9 clone (with a sandpapered cpu with 74hc244) since almost a year, for which I didn't had any problem programming my boards in AS mode, or JTAG direct mode until now.
