We are creating applications that utilize Boot Mode [1,1] SPI boot mode on the Blackfin BF533. We are seeking additional details on the boot kernel/ROM and how it initializes the SPI bus registers: SPI_BAUD, SPI_CTL, etc. Any other specific internal Blackfin registers as well. Is there a document that describes in detail the operation of the Boot kernel? Possibly the boot kernel source code for reference? We have reviewed EE-240 app note but, it lacks certain details.
