The ROM code allows booting from SPI memories connected to the QSPI controller. The QSPI_MODE bit must be set in the Boot Configuration Packet.

SPI Flash Boot supports only SPI Serial Flash devices.

The SPI Flash read is done by means of a Continuous Read command from the address 0x0. This command is 0x0B for Serial Flash devices.

Supported Serial Flash Devices

The SPI Flash Boot program supports all SPI Serial Flash devices responding correctly to the Get Status and Continuous Read commands.
