STM32F411 Microcontroller has 512KB Flash. I assume Bootloader and Application resides here (DCT files reside here too?)
Avnet Board also provides 8MB SPI Serial Flash. When Wifi link is down, i want to store data on the Module and send it to the Cloud when the link is up. I assume i can use the 8MB SPI Serial Flash for this purpose. Can you please point me to an example for read/write to SPI Flash?
