If the dataflash is ready, DataFlash boot reads the first 8 words into SRAM (Instruction code
“Continuous Read Array” 0x0b) and checks if it corresponds to valid exception vectors according
to the Valid Image detection algorithm.
If a valid application is found, this application is loaded into internal SRAM and executed by
branching at address 0x0000_0000 after remap. This application may be the application code or
a second-level bootloader.
The DataFlash boot is configured to be compatible with the future design of the DataFlash.
