Hi,

I faced a similar problem with the same Max II 1270 dev kit with ES device. I followed wahilakn's comment and modified the .qsf file by adding "ES" 


set_global_assignment -name DEVICE EPM1270F256C5ES

but I was getting another error, this time from the Fitter(Place and Route): 


Error: The supply voltage value 3.3V applied to the 'VCCINT' power rail is illegal for the currently selected device.

which was not a hardware issue, since the device is rated for both 2.5V and 3.3V by jumper J9 setting.

So I had to comment out this line: 


# set_global_assignment -name POWER_EXT_SUPPLY_VOLTAGE_TO_REGULATOR 3.3V

I am able to program the device after this modification.
