Hello
As i've already read I am not only person having this problem. Besides of this, I could not find anyone who uses the same configuration as I am.
I have Logic omapl138 EVM, which contains of a 8MB SPI memory, and MMC/SD slot
UBL,U-boot, and linux kernel are loaded into this memory.
rootFS is loaded into SD card. (This is microSD in SD adapter)
Everything works fine, when I am using ready kernel uImage file (provided with the EVM)
When I am trying to develop my own configuration, and load the kernel into memory, I got a fallowing problem

This also does nothing.
I am out of ideas. Please Help me.
