"BF609 SPI Master Boot Mode" can only select SPI0 it? SPI1 can choose it?
As detailed in the BF60x Blackfin Processor Hardware Reference Manual, the SPI Master Boot Mode boots from SPI memory connected to the SPI0 interface. It cannot access SPI1.
However, as explained in the "Boot ROM and Booting the Processors" chapter, the Boot Routine API function can be used to initiate a boot - including customization to boot from another device. Of course, in order to trigger this API you would need to boot from another source (e.g. SPI0, Parallel Flash, etc) to run an application that invokes the Boot Routine API.
