Honored ContributorI was wondering if there has been a solution yet...
I got a similar issue: having compiled an .sof in my QuartusII 10.1 and JTAG programming (or better configuring) with the same release my EP3C10 Cyclone succeeds: -- Info: Configuring device index 1 Info: Device 1 contains JTAG ID code 0x020F10DD Info: Configuration succeeded -- 1 device(s) configured Info: Successfully performed operation(s) -- But neither 'Create/Update jam/jbc/svf...' nor quartus_cpf generate an .jam file that successfully configures the FPGA, JTAG output is: -- Info: Programming status: Device# 1 IDCODE is 020F10DD Info: Programming status: configuring SRAM device(s)... Info: Programming status: Device configuration failure Error: Operation failed --- Also the JTAG waveform shows some difference: - .sof case: nSTATUS goes high from pulsing before, CONF_DONE ok - .jam case: nSTATUS continues pulsing, CONF_DONE not ok It seems that the conversion .sof -> .jam lost some crucial configuring. Also a 'quartus_cpf -c my.cdf my.jam' did not succeed. Does anybody know what the difference in the sequences could be and how to mitigate it? Thanks, Seb.
