How can I unprotect the block protect bit registers BP[2..0] in EPCS or EPCQ configuration devices without using the Altera ASMI Parallel IP? - How can I unprotect the block protect bit registers BP[2..0] in EPCS or EPCQ configuration devices without using the Altera ASMI Parallel IP? Description You can use quartus_jli and a .jam file generated from a .JIC file to unprotect the block protect bits in an EPCS or EPCQ configuration devices. T he generated .jam file will contain the appropriate programming algorithm for this procedure. Resolution You can use quartus_jli to execute the optional procedure from the .jam file to unprotect the BP[2..0] registers in the EPCS or EPCQ configuration devices as shown below. If using the quartus_jli executable, the command would be: quartus_jli –aPROGRAM –eDO_EPCS_UNPROTECT <filename>.jam If using the JAM STAPL player, the command would be: jam –aPROGRAM – dDO_EPCS_UNPROTECT=1 <filename>.jam The JAM STAPL Byte-Code (JBC) Player uses the same command as above to run a .jbc file, except for the executable name.
