Hi, zhou

Everytime system power up, boot ROM will be always running first, then it will call plugin to init power, DRAM...there is a file linux.bd in linux-bootlets, I think you can put your test image here, then call it and run it. But you still need to program it into NAND flash, and set system to boot from NAND, then ROM will try to read the image in NAND and run it in DRAM, not sure whether this is what you want.....

I'm tring to make the OBDS program runing on Nand Flash.it works well in SD card.

but when I flash it into Nand with MFGTool, there no response at all ,and the MFGTool detected the HID compliant Device, which means boot from Nand failed.
