Hi,
Hi,
I am using mx51 base board, I want to make u-boot booting from nand flash. Does anyone knows how to modify the u-boot source?
You have to add support for the NAND controller, not yet in mainline.
Does add some code to init the nand flash controller in flash_header.S's dcd section?
You are not talking about u-boot sources in mainline. Linking the DCD together with u-boot is the original development by Freescale.
There is no flash_header.S in u-boot.
In mainline, an header is added to the binary providing a different image that can be loaded into the storage. See doc/README.imximage. This is consistent in u-boot because other processors use the same approach.
Does anyone have u-boot booting from NAND on mx51? Any repository, or a patch that might be available?
At the moment, NAND is not supported in u-boot mainline for the MX.51. Patches are welcome ;-)
