There are few things you need to look at:

1. Open SOPC builder and check your CFI controller is placed on 0x01400000 and exception is not given on CFI (if reset vector is on flash, it is OK)

2. You have selected correct size and timing parameters in CFI controller which matches your flash device on board

3. You have downloaded same .sof file and generated project using .ptf file from same project

4. Make sure Flash programmer's current instance is taking reference of same nios project you are working on (else you just delete all instances of flash programmer and re instance again by selecting your working project)

5. Check System Library Properties of Nios II project and make sure read/write memory, stake memory, heap memory are not falling into flash device. Keep it in volatile device like sdram or ssram or onchip ram.
