I'm a bit new to manipulating the flash but....
You need to define the following macros:
CYGHWR_FLASH_WRITE_ENABLE()
CYGHWR_FLASH_WRITE_DISABLE()
If you don't they are a no-op and you'll never put the power to flash.

Hi All,
I am working on Intel FLASH 28F160C3B Chipset Device driver.
I have modified "28fxxx port" to support 28F160C3B. I have compiled and
Installed in my system using ROMRAM Startup Type.
When I am try to initialize the FLASH using "fis init" command I am getting
the following message:
"---------------------------------------------------------------------------
RedBoot> fis init
About to initialize [format] FLASH image system - continue (y/n)? y
*** Initialize FLASH Image System
Warning: device contents not erased, some blocks may not be usable
... Unlock from 0x501f0000-0x50200000: .
... Erase from 0x501f0000-0x50200000:
Error erasing FIS directory at 0x501f0000: Device reports low voltage
... Lock from 0x501f0000-0x50200000: .
-------------------------------------------------------------------------"
Did anyone come across this type of error..?
Please guide me to solve this problem.
Thanks in Advance.
Regards,
Vinayagam.M
