As suggested by waiyung, I solved my problem setting following timings, despite as suggested by flash memory datasheet:

# define CFI_FLASH_HOLD_VALUE 50

# define CFI_FLASH_SETUP_VALUE 50

# define CFI_FLASH_WAIT_VALUE 160.

For example wait time should be set to 90/100 but we need 160. I faced that working in debug mode memory requires wait time greater than one required in usual operation (not run and not debug mode).

Bye bye
