Error (209048) during flash programming with PFL

SW: Quartus Prime 16.0 SP2 

Cable: USB Blaster Rev.B 

CPLD: EPM1270T144C5 

Flash: Intel StrataFlash PC48F4400P0VB0EE 

 

 

Flash erase & programming pass with success. 

Verfication fails.

Failure address can be 0x00020000-0x00020800 or 0x00020800-0x00021000 

It may change after another programming procedure. 

 

 

However verification of OPTION_BITS only is always successful.

Flash and I/O power is OK. 

 

 

1. There are several P30 parts with different timings: 100/110ns and 85/88ns.  

Program and Erase Characteristics are different as well. 

But Manufacturer & Device ID Codes are exactly the same for all of the devices. 

 

 

Can it possible be that Quartus takes parameters from the fastest device? So slower devices do not operate properly. 

 

2. PFL was generated with "Flash Programming" option only. 

.sdc file was not specified.  

All constraints that could be set are "set_false_path" according to PFL UG for asyncronous mode (Table 7). I decided not to set them at all. 

Am I wrong and some constraints must be set? 

 

Previous board with EPM570 and the same flash device, power and pinout scheme worked fine. Q11.1 was used.
