Hi,
I have compiled u-boot-latest with ELDK 4.1 for AT91RM9200EK board (as I have kept the memory configurations and crystals similar to the board).I am getting something on the hyper terminal now. My hyperterminal configuration 115200-8-N-1 Given below is the snapshot as it comes.
U B-oo t02900. 8F(be2 20201- 1 :1041:)5
I2C: ready DRAM: !!BM
Please let me know if somebody faced a similar situation or any pointers to get out of this problem.
Regards Raj Nikumbh

OK, then can you explain what software do you flash? Does rm9200 u-boot setup PLL? Because if it is not then you will never see anything at DBGU pins. Another problem can be with your RC filters for PLL. Did you use the same quartz as in the Atmel design? If not then you must calculate RC filters and change them on your board.
BTW, if your SDRAM does not work then u-boot will never start :)

Yeah I did pull it down at the startup. And I meant the same DBGU pins.
the board support in board/eukrea/cpuat91 was working fine last time I tested it and this board is close to your configuration (AT91RM9200 + NOR Flash 16bits width) so maybe you can try it (you may just need to update SDRAM geometry and timings and SMC timings for your NOR flash).
