Hi, When partitioning the target board's NAND memory for first time(board which dont have any software before), using Uboot bootloader with kernel partition,bootloader partition, root filesystem partition, how does the bootloader instruct the kernel about the memory address of root filesytem to load after kernel was loaded in the power up sequence? In kernel where will this address info stored after partitioning as the kernel image will be generated in the host environment and at that time kernel image was not aware of these address and after bootloader loads the kernel it transfers the control to kernel? Please reply!
