Hi,

no idea about JAM, sorry. However, when using the Quartus Programmer with the USB Blaster to program a MAX V, UFM is separate from CFM (configuration flash memory). Just flashing the configuration file (which contains you IP) won't touch UFM.

If you can program your CPLD using the Quartus Programmer, program the .sof file that Quartus generated into UFM. It is the same .sof file that you flashed into CFM.

Again, no idea about JAM, but I assume whatever tool you use, there might be an option to program into UFM explicitly.

Another idea: since you're using the UFM IP, maybe you can program the UFM using that UFM IP in the live CPLD? I assume your CPLD design doesn't provide a writing interface, but if anything else fails, you could maybe furnish an alternative CPLD design which you initially program into CFM to program the UFM.

Best regards,
