I am working on Stm32f427. I want to interface EEPROM with this microcontroler for external booting. The external booting options mentioned in referance manual are from system memory and SRAM. Please tell me how to interface EEPROM with this microcontroller. Can I use SRAM for booting through EEPROM?

You will have to build your own loader to pull code from the EEPROM device. If it can be interfaced via the FSMC/FMC you may be able to execute the code in-place, but your loader would still need to configure the external bus, and transfer control.

External memory generally operates significantly slower than internal memory, and is usually avoided for code execution for those reasons.

Speed is not an issue. Can you tell me how to build loader to pull out the code from the EEPROM.

I could, but I have more pressing work to do.
