DataFlash Boot Sequence
AT91SAM9261S
Figure 13-6. Serial Flash Download
The Dataflash boot looks for a valid application in the SPI DataFlash memory.
SPI0 is configured in master mode to generate a SPCK at 8MHz. Serial Flash shall be con-
nected to NPCS0.
The DataFlash boot reads the dataflash flash status register (Instruction code 0xD7). The data
flash is considered as ready if bit 7 of the returned status register is set.
If no dataflash is connected or if it does not answer, DataFlash boots exits after a 1000 attempts.
Read the SerialFlash into the internal SRAM.
Restore the reset value for the peripherals.
Set the PC to 0 and perform the REMAP
