AM1806 u-boot board port

Hi to everybody,

I explained custom board I made on http://e2e.ti.com/support/dsp/omap_applications_processors/f/42/p/312497/1091823.aspx#1091823 .

I'm new in arm system programming and configuring and in post above I explain some problems I had.

Till now I solve the following problems:

1) I finish with loading and flash utility custom build. On am1808 evm debug port is UART2, on my board debug is UAR0. Because of that I had to make custom build of this tool. After building the tool I had success to erase SPI flash on board.

2) I build custom UBL for proccesor and flash it in UBL. After that I change boot type to SPI flash and its working for me.

Now I'm trying to configure and rebuild u-boot. Because my board is almos the same to am1808 som m1 from logicpd in da850evm.h I changed only #define CONFIG_SYS_NS16550_COM1DAVINCI_UART2_BASE to UART0_BASE. If I'm right that means that UART0 will be debug port. When I flash UBL.bin and u-boot.bin to SPI Flash and turn on board I got next message on serial port terminal:

OMAP-L138 initialization passed!
Booting TI User Boot Loader
UBL Version: 1.65
Device OPP (300MHz, 1.2V)
UBL Flashtype: SPI
Starting SPI Memory Copy...
Valid magicnum, 0x55424CBB, found at offset 0x00010000.
DONE
Jumping to entry point at 0xC1080000.

Can somebody explain to what is the problem, and give me some good tutorial link how to configure u-boot.

Thanks a lot for your answers.

Regards Miroslav.
