I am fresh engineer in this field working with DM6446 EVM DAVINCI boardwhich contains DSP as well ARMEJ9. I need to bring that board up. I don't have any experience of how to load the boot loader, how the things goes after boot loader get loaded, so and so. I am working by reading all the document in u-boot source tree and going through the code of u-boot-1.1.3.
Why are you starting with OLD code? Please use the top of tree from the git repository instead!
am confused that how to write the image in NAND FLASH, thats why I am using the other option and that is to download the boot image from UART where one host utility will be runing on the host PC that does few handshaking with board's primary boot loader and than downloads secondry boot loader from the host PC.
You should really start reading the FAQ.
