Hello, help me configure the u-boot loader so that spl can load the u-boot image from the spi flash drive. currently, only MMC0 and MMC1 are being checked.

Function board_boot_order print “could not map node to a boot-device” for every device exept mmc0 and mmc1

Thanks

To configure U-Boot SPL to load from SPI flash, modify the u-boot configuration file by enabling CONFIG_SPL_SPI_SUPPORT and CONFIG_SPL_SPI_FLASH_SUPPORT. Then set the CONFIG_SYS_SPI_U_BOOT_OFFS to define the offset where the U-Boot image is stored in SPI. Update the CONFIG_SPL_BOOT_ORDER to include SPI flash alongside MMC options.
