This is my configuration: /* Defines for SPL */ #define CONFIG_SPL #define CONFIG_SPL_TEXT_BASE 0x40303000 #define CONFIG_SPL_MAX_SIZE (45 * 1024) #define CONFIG_SPL_STACK LOW_LEVEL_SRAM_STACK The MLO binary has 46094 Bytes. Actually I should have enough space (from 0x40300000 - 0x4030bfff -> ~49 kB). However, the device does not start. Right now I am reviewing the code to check, whether it is because of the code and not because of the size that makes u-boot does not start.
