CC3220SF-LAUNCHXL: Can serial flash be accessed without Host APIs?

Lin Gao58

I'm evaluating if it's possible to access the serial flash on the board directly from the MCU without using the provided Host APIs. That is, use it as a generic SPI flash to store raw data, or put my own filesystem. From the reference manual, these pins are all reserved. Can someone tell me if it's doable?

Thanks,

Hi Lin,

Direct access from application processor to serial flash (sFlash) is not supported. This flash chip is used as storage for network processor (NWP) and ROM bootloader as well. For access to sFlash you should use filesystem host API.
