When you execute the PROGRAM action in the .jam or .jbc file, the PFL will typically perform erasing, programming and verifying process. Hence it will take a longer time to complete the CFI flash programming. You can skip the verify operation when programming the CFI flash device, by disabling the DO_VERIFY procedure, when executing the .jam or .jbc file.
If using the quartus_jli executable, the command would be :
quartus_jli –c<cable index> –aPROGRAM –dDO_VERIFY <filename>.jam/.jbc
If using the JAM STAPL player, the command would be:
jam –aPROGRAM –dDO_VERIFY=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.
