xomap4430 serial booting problem

I have a boot problem with omap4430 at  ROM boot stage.

I have PandaBoard A2 and custom xomap4430 board. 

SYSBOOT pins are configured for booting from UART as 1-st boot device to see ASIC-ID structure.

So, PandaBoard sends:

04 01 05 01 44 30 07 02 13 02 01 00 12 15 01 

and works fine.

But my custom xomap4430 board sends:
04 01 05 05 23 09 74 18 B0 62 81 01 00 24 55

and can't execute any 1-nd stage boot loader (MLO).

So, the string 04 01 05 05 23 09 74 18 B0 62 81 01 00 24 55 repeat after reset.

For information:

04 Number of subblocks
01 0x01: Subblock ID
05 0x05: Subblock size
01 0x01: Fixed value
0x44 0x30 cpu version
07 0x07: CH enabled (read from eFuse)
02 ROM revision

Please help me to recognize the boot problem.


Thanks beforehand.
