This puts the Rockchip header and SPL image first and then places the U-Boot -image at block 256 (i.e. 128KB from the start of the SD card). This +image at block 16384 (i.e. 4MB from the start of the SD card). This corresponds with this setting in U-Boot:
- #define CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR 256
- #define CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR 0x4000
Could you use 'u-boot,spl-payload-offset’ to provide this info to U-Boot or is there a strong reason to hard-code this?
Put this SD (or micro-SD) card into your board and reset it. You should see something like: -- 1.9.1
