EEPROM Write Issue using SPI (STM32F779BI)

Hello ,

I am working on project in which I have to write data to EEPROM using SPI.

I am able to write data to eeprom successfully when I disable CPU I-Cache and D-Cache

otherwise it failed.

so is it necessary to disable both cache while using EEPROM or that's my mistake ?

Is SPI is working on constant freqency ( in my case prescaler 13.5 ) ?

I am able to write successfully to EEPROM after disable that I-Cache and D-Cache

Part Number : STM32F779BI

EEPROM : AT25M02-SSHD-T

Thanks
