This is something between a matter of taste and an urban legend.
I don't think so. If you have brand new board to test, you can't be sure that everything is working at all. Things inside of cpu are most propably ones that work. That means internal SRAM, UART and with little external support ethernet.
In either case nothing appears in to the console. Also, allways the address is same and i got the step timeout.
Did you contact Abatron support? What did they say (except for: check for hardware problems - which I'd say, too).
The reason why i don't think that it is not hw problem in abatron or board but rather some incompatibility with bdi2000 initialization and u-boot. The abatron works without problemt to load my own code to internal sram, i can start and run it etc. I was expecting something same than Dan Malek said that there is something with debug register write etc.
For some reason the both cases, trace and starting with go fails in same place ( before or after bl )

Also the board works, u-boot works, the board boots and runs linux etc. The only thing that don't work is u-boot with bdi2000 connected.
with bdi2000. There is something that i did wrong with bdi2000 configuration and i try figure out what.
Which differences are between your board and the LITE5200?
There is lot ot abot nothing diferencies. In basic boot level it is wery compaible with LITE5200. Only meaningfull diference is that boot flash is diferent. I just needed to change u-boot to support intel-compatible flash algorithm and change flash size to get it working.
The most diferencies goes in expansions. My board has NAND flash for filesystem, MMC for filesystem, TI2301 audio codec/touch screen/system ADC, two banks of SDRAM and FPGA for LCD display controller and i-o expansion use. The board is http://www.iti.fi/iti5200.php
I was just working to make u-boot to boot kernel from nand flash or mmc.
