82574IT GbE controller EEPROM or FLASH which is best?

Hello, I am currently designing a system using the 82574IT chip, the data sheet says we can use either Flash or EEPROM. Does anyone know if there is a downside to using EEPROM. Can it still be programed via the PCIe memory map? As the map only mentions Flash.

Thanks

Hello, there is a command for u-boot that does what you need. Look for "e1000 u-boot":

e1000: Allow direct access to the E1000 SPI EEPROM device

As a part of the manufacturing process for some of our custom hardware,

we are programming the EEPROMs attached to our Intel 82571EB controllers

from software using U-Boot and Linux.

Regards
