Hi All,

I need to know how the control is passed from u-boot to kernel in Linux operating syste

Per my understanding, uboot will save what kernel needs to registers before jump to the entry point. The contents of the register and which registers are needed is architecture defined. You may check kernel/uboot source for your architecture. HTH,

Reading the uboot source code: In common/cmd_bootm.c: int do_bootm (cmd_tbl_t *cmdtp, int flag, int argc, char *argv[]) { And within this do_bootm_linux() is called: do_bootm_linux (cmdtp, flag, argc, argv, addr, len_ptr, verify); And inside do_bootm_linux() (platform-specific, for x86 it is lib_i386/i386_linux.c) is the load_zimage() function being called, which is effectively loading the kernel image file.
