Abstract
When JTAG is used to import sof of Quartus II without modification to de2, it will be no longer needed for a single power supply, so we want to import it to the Apsara stack, in this way, the computer can be connected immediately, but the above warning messages may occur.
Symptom
Environment: US us II 7.2 SP3 + de2 (Cyclone II ep2c35f672c6)
Originally, JTAG was used in de2, and both of them can be used normally. However, after swtich is switched from run to prog, the following warning messages are generated using programmer:
Solution
To upload a program to the flash drive, follow these steps.
Step 1:
Set the epcs16 flash
Assignment-> device: Device and pin options-> deployments
Step 2:
Set programmer
Switch Mode from JTAG to active serial programming, and inject *. POF to program/configure, and switch de2 from run to prog.
When switching from JTAG to active serial programming, the following warning message is displayed. Select Yes.
Later, it takes some time to upload data to the flash, about one minute or more.
Step 3:
Reactivate de2
Run de2 again and switch from prog to run.
Download the complete program

Conclusion
I will only introduce the emphasis of programmer into flash. If you want to improve the programming process, please take the test (formerly known) Quartus II and de2 newbie tutorial (IC design) (de2) (Quartus II), this file must be written more frequently.
