It uses an old mechanism called bootlets. I suggest that we start from scratch with this imx28-wink-hub support that I have just added: https://github.com/fabioestevam/u-boot/commits/wink To build it: make imx28-wink-hub_defconfig make u-boot.sb Then try to load u-boot.sb via mxsldr. If it still fails, then I suspect that the power management unit (PMU) may be incorrectly configured causing the board to not power up. Try playing with the CONFIG_SPL_MXS_PMU_ options. >From configs/imx28_xea_defconfig, for example: CONFIG_SPL_MXS_PMU_MINIMAL_VDD5V_CURRENT=y CONFIG_SPL_MXS_PMU_DISABLE_BATT_CHARGE=y # CONFIG_SPL_MXS_PMU_ENABLE_4P2_LINEAR_REGULATOR is not set
