Custom Boot Mode with SD card

Category: Software
Product Number: ADSP-SC589


We want to be able to have a second stage bootloader on QSPI flash, that loads the loader stream from SD card which also supports secure boot.

I've been looking at EE447, but the example provided here doesn't hook into adi_rom_BootKernel but instead uses adi_rom_Boot on octal SPI, for reasons that I don't understand.

My understanding is that i'd need to use adi_rom_BootKernel and provide a pBootConfig struct to this, but it also isn't clear what options I need to set in pBootConfig.
