Did you correctly reset the processor after changing boot mode from SD card to eMMC? Did you correctly select the uSDHC port your eMMC chip is connected to (the state of the BT_CFG2_3 signal, that affects the uSDHC port selection, is not shown on your pictures)? Are all other BT_CFGx_y signals pulled down to 0 at the moment of reset?
Also, try not to use the eMMC 4.4 DDR mode during boot, i.e. pull the BT_CFG2_7 signal down to 0.
