| Not all board variants are represented with a specific defconfig in |
| mainline U-Boot. Here a small documentation on how to generate U-Boot |
| images for all other board variants, available via different dts |
| files and defconfigs. |
| |
| Use a different dts than in the defconfig: |
| |
| make DEVICE_TREE=cn9131-db-B |
| |
| Use a different boot device (e.g. MMC or NAND instead of SPI NOR): |
| |
| For MMC, please make the following changes to the defconfig via |
| e.g. "make menuconfig": |
| Remove CONFIG_MVEBU_SPI_BOOT |
| Select CONFIG_MVEBU_MMC_BOOT |
| Remove CONFIG_ENV_IS_IN_SPI_FLASH |
| Select CONFIG_ENV_IS_IN_MMC |
| |
| For NAND, please make the following changes to the defconfig via |
| e.g. "make menuconfig": |
| Remove CONFIG_MVEBU_SPI_BOOT |
| Select CONFIG_MVEBU_NAND_BOOT |
| Remove CONFIG_ENV_IS_IN_SPI_FLASH |
| Select CONFIG_ENV_IS_IN_NAND |
