Honored ContributorI've received my new USBlaster which use FT245+CPLD yesterday.
I've got the JTAG-Indirect-SFL working to program the EPCS flash correctly, but unfortunately, this new clone is unable to do "examine", it shows the following : Info (209060): Started Programmer operation at Fri Mar 7 11:05:22 2014 Info (209016): Configuring device index 1 Info (209017): Device 1 contains JTAG ID code 0x020F10DD Error (209040): Can't access JTAG chain Error (209040): Can't access JTAG chain Error (209015): Can't configure device. Expected JTAG ID code 0x020F10DD for device 1, but found JTAG ID code 0xFFFFFFFF. Error (209053): Unexpected error in JTAG server -- error code 35 Error (209012): Operation failed Info (209061): Ended Programmer operation at Fri Mar 7 11:05:23 2014 But even programming, for which it succeed one time, it seems to be intermittent, another trial failed : Info (209060): Started Programmer operation at Fri Mar 7 11:08:44 2014 Info (209016): Configuring device index 1 Info (209017): Device 1 contains JTAG ID code 0x020F10DD Error (209040): Can't access JTAG chain Error (209015): Can't configure device. Expected JTAG ID code 0x020F10DD for device 1, but found JTAG ID code 0x00820F10. Error (209012): Operation failed Info (209061): Ended Programmer operation at Fri Mar 7 11:08:45 2014 Some other trials failed to communicate with SFL : Info (209060): Started Programmer operation at Fri Mar 7 11:11:15 2014 Info (209016): Configuring device index 1 Info (209017): Device 1 contains JTAG ID code 0x020F10DD Info (209007): Configuration succeeded -- 1 device(s) configured Error (209062): Flash Loader IP not loaded on device 1 Error (209012): Operation failed Info (209061): Ended Programmer operation at Fri Mar 7 11:11:16 2014 And finally, without doing anything special, I got it worked once : Info (209060): Started Programmer operation at Fri Mar 7 11:17:26 2014 Info (209016): Configuring device index 1 Info (209017): Device 1 contains JTAG ID code 0x020F10DD Info (209007): Configuration succeeded -- 1 device(s) configured Info (209018): Device 1 silicon ID is 0x14 Info (209044): Erasing ASP configuration device(s) Info (209023): Programming device(s) Info (209011): Successfully performed operation(s) Info (209061): Ended Programmer operation at Fri Mar 7 11:17:35 2014 Also, on some other FPGA boards, Quartus programmer is unable to connect to JTAG chain at all. So, I guess I will have to purchase a more expensive USBlaster if I don't want to suffer of all those troubles anymore.
